**Short answer:** To start an HR tech startup without VC, build one narrow tool for small employers (leave tracking, shift scheduling, onboarding, hiring for one industry, or 1:1s) instead of an all-in-one HR platform. Price it the way small businesses already buy HR software, per business or per employee, distribute it through the tools they already use (Slack, Microsoft Teams, Gusto, Xero), and treat employee data protection and AI hiring rules as product requirements from the first version.

Every price, rule and figure below comes from a vendor, regulator or founder page checked on 12 Nov 2026 and linked inline. The strategy around them is ours and is marked as such. Nothing here is legal advice.

## TL;DR

- **Go narrow, go small.** All-in-one HRIS and payroll need money and years of compliance work. A leave tracker, a rota tool for care homes, or an applicant tracker for dental clinics can be sold by one founder.
- **Small employers already pay.** [When I Work](https://wheniwork.com/pricing) lists $2.50 to $8 per user per month, [Deputy](https://www.deputy.com/pricing) $5 to $9, [15Five](https://www.15five.com/pricing) $4 to $16 billed annually, and [Breathe](https://www.breathehr.com/en-gb/hr-software/hr-software-prices) charges per business from £24 a month for 1 to 10 people.
- **Employee data is sensitive by default.** The ICO says employers "must carry out a DPIA before undertaking any processing likely to cause high risk" when monitoring workers ([ICO](https://ico.org.uk/for-organisations/uk-gdpr-guidance-and-resources/employment/monitoring-workers/data-protection-and-monitoring-workers/)). Your product inherits that question.
- **AI hiring is regulated.** NYC Local Law 144 requires a bias audit within one year before an automated employment decision tool is used ([NYC DCWP](https://www.nyc.gov/site/dca/about/automated-employment-decision-tools.page)), and the EU AI Act lists recruitment AI as high-risk ([Annex III](https://artificialintelligenceact.eu/annex/3/)).
- **Watch integration costs.** [Merge](https://www.merge.dev/pricing) lists $650 a month for up to 10 linked accounts; [Finch](https://www.tryfinch.com/pricing) Starter is $65 per connection per month.
- **It has been done.** [Vacation Tracker](https://vacationtracker.io/blog/0-to-3m-arr-how-two-bootstrapped-founders-built-vacation-tracker-and-brought-in-a-100m-ceo/) never raised external funding and is approaching $3M ARR; [Pinpoint](https://workwithus.pinpointhq.com/faqs) bootstrapped to £5M ARR before taking private equity.

**Disclosure:** ZeroRaised publishes this guide and is a launch site for bootstrapped products. ZeroRaised has no commercial relationship with any vendor, regulator or company named here and earns nothing if you buy from them. This is general information, not legal or employment advice; talk to a qualified adviser in each country you sell into before you ship anything that makes or supports decisions about people's jobs.

## Why HR tech looks like a VC game (and when it is not)

HR tech headlines are dominated by large rounds for global payroll, employer of record services and all-in-one HR platforms. Those businesses have good reasons to raise. Payroll touches tax filings in every jurisdiction, mistakes cost real money, and switching away from an HRIS is painful, so the winners spend years and large budgets earning trust before they earn much revenue. Enterprise HR buyers add long procurement, security reviews and implementation projects.

The other half of the market is quieter. Millions of small employers (a restaurant with 25 staff, a dental group with four sites, a 40-person agency) run HR on spreadsheets, WhatsApp groups, paper forms and a payroll provider. Their problems are narrow and annoying: who is off next week, who can cover Saturday, whether the new hire has returned their right-to-work documents, when the last 1:1 happened. A manager or owner can approve a tool that fixes one of those on a card, in one call.

That is the bootstrapped shape of HR tech, and it is the same logic as our [vertical SaaS without VC playbook](https://zeroraised.com/blog/how-to-build-a-vertical-saas-without-vc): pick a narrow problem in a defined group of buyers, and own it. HR adds three twists, which most of this guide is about:

1. **The people in your database are not your customers.** Your buyer is the employer, but the data belongs to employees and candidates, who have rights of their own.
2. **Decisions about jobs are regulated.** Anything that helps decide who gets hired, promoted, scheduled or fired can fall under discrimination law and, increasingly, specific AI rules.
3. **You live next to systems you do not control.** Payroll, HRIS, chat tools and accounting software already hold the employee list. Integration is both your biggest cost and your best distribution.

Our read: you are not trying to beat the HR platforms. You are trying to be the best tool for one job that the platforms do badly for one kind of employer, and to plug into whatever platform that employer already has.

## Pick your wedge

Here is how we would rank the main HR tech categories for a founder without investors. This is our judgement, not market data.

| Category | Who buys | Sales cycle | Regulatory weight | Our read for bootstrappers |
|---|---|---|---|---|
| Leave and absence tracking | Owner, office manager | Days | Low to medium (leave law varies) | Strong: universal pain, easy to try |
| Shift scheduling for one industry | Ops or site manager | Days to weeks | Medium (working time rules) | Strong if you own a vertical |
| Onboarding and document collection | HR generalist, owner | Weeks | Medium (right-to-work, ID data) | Good, especially for high-turnover sectors |
| Applicant tracking for one vertical | Hiring manager, owner | Weeks | Medium to high if AI screens people | Good if you stay narrow and keep humans deciding |
| 1:1s, check-ins and performance | Team leads, founders | Days to weeks | Low unless you score people | Good, crowded at the top end |
| Engagement and pulse surveys | HR, CEO | Weeks | Low (anonymity is the issue) | Fine as a feature, hard as a standalone business |
| HR compliance helpers for SMBs | Owner, HR consultant | Weeks | High (you are interpreting law) | Good with a domain expert co-founder |
| Full HRIS or payroll | HR director, finance | Months | Very high | Avoid without serious capital |

### Leave and absence

Every employer with more than a handful of staff tracks time off, and most do it badly. The product is easy to understand and easy to trial, and it naturally lives inside the chat tool a team already uses. The competition is real, but country-specific leave rules, sector-specific patterns (school term holidays, shift-based accrual) and better calendar integrations leave room. Vacation Tracker, covered below, is the proof that this wedge can carry a company.

### Shift scheduling for one industry

Generic scheduling tools are cheap and mature, as the pricing table later shows. The opening is depth in one industry: care homes that need qualified staff ratios on every shift, clinics that need a nurse and a dentist in the same room, construction crews tied to site certifications, restaurants that need tip and break rules for one US state. Our read: if you cannot name the rule that a generic scheduler gets wrong for your industry, you do not yet have a wedge.

### Onboarding and document collection

High-turnover sectors hire constantly and drown in forms: contracts, ID checks, certifications, bank details, policy sign-offs. A tool that collects, checks expiry dates and reminds people is valuable and simple to explain. It also holds identity documents, which raises your security bar from the first customer. See the data section below.

### Applicant tracking for one vertical

Workable's Standard plan costs $299 a month on monthly billing ([Workable pricing](https://www.workable.com/pricing)), which is a lot for a single dental practice hiring two people a year. A narrow ATS for one sector, with the job templates, screening questions and job boards that sector uses, can win on fit and price. Pinpoint shows that an ATS can be bootstrapped to real scale, though it sells to in-house talent teams rather than to tiny employers.

The risk to manage is AI screening. As soon as your product ranks or filters candidates, you may be building an automated employment decision tool under NYC law and a high-risk AI system under EU law. We cover both below.

### 1:1s, performance and engagement

Lattice and 15Five publish per-seat prices for performance and engagement (see the pricing section). They sell mostly to companies with an HR function. Below that, founders and team leads at 10 to 50 person companies still run 1:1s in a doc. Our read: a lightweight tool for managers, sold bottom-up, can work, but anonymous engagement surveys alone are a feature that larger platforms bundle, so pair them with something people use every week.

### HR compliance helpers

Small employers are scared of getting HR law wrong: contracts, right-to-work checks, holiday pay calculations, handbook policies, I-9s in the US. Tools that turn rules into checklists, templates and reminders sell well, often through HR consultants. They need a domain expert, because a wrong answer is costly for the customer and for you.

### Pick a vertical inside the category

The pattern across all of these is the same: category plus industry. "Scheduling" is a crowded market. "Scheduling for UK domiciliary care agencies" or "onboarding for US franchise restaurants" is a business a solo founder can own. Our read: industries with shift work, licences and high turnover (care, hospitality, retail, construction, clinics, cleaning, security) have the sharpest HR pain and the least software built for them.

## Validate with HR buyers

HR buyers are polite. They will tell you an idea is interesting and then never use it. Run the interview and pre-sale process in our [guide to validating a SaaS idea before building](https://zeroraised.com/blog/how-to-validate-a-saas-idea-before-building), with a few HR-specific adjustments.

**Talk to the person who does the work, then the person who pays.** In a 30-person restaurant group the general manager builds the rota and the owner signs the card. In a 200-person company an HR generalist does the work and an HR or finance lead approves. Interview both.

**Ask to see the current system.** The leave spreadsheet, the rota WhatsApp group, the onboarding email template, the folder of scanned passports. The mess tells you more than any answer. If they cannot show you anything, the pain may not be real.

**Ask what happens when it goes wrong.** Someone not paid correctly for holiday, a shift nobody covered, a new hire who started without a right-to-work check, a candidate who complained. The cost of failure is what justifies your price.

**Ask what they pay now.** Payroll provider, scheduling app, HR platform, an HR consultant on retainer. That sets your price anchor and shows you which system you must integrate with.

**Ask for money.** A paid pilot, an annual pre-payment at a discount, or a signed letter of intent with a price. In HR, "we would need to check with legal" is a real objection. Note it, find out what legal would ask, and build that answer.

Where to find buyers to interview: HR communities and local CIPD or SHRM chapters, industry associations for your vertical, HR consultants (who talk to dozens of small employers each month) and accountants who run payroll for small businesses. Our read: one well-connected HR consultant who likes your idea is worth twenty cold interviews, because they can introduce you to five clients and later resell your tool.

## Employee data: your buyer's duties become your spec

HR software is one of the most sensitive categories of B2B data you can hold. It contains names, addresses, salaries, bank details, identity documents, performance notes, disciplinary records and, often, health information through sickness absence. Employers know this, and their questions will shape your product.

### UK and EU GDPR

In the UK and EU, your customer is usually the controller of employee data and you are their processor. That means a data processing agreement, a list of subprocessors, security measures and help with access requests. Our [GDPR checklist for solo SaaS founders](https://zeroraised.com/blog/gdpr-checklist-for-solo-saas-founders) covers the basics; this section covers what is different in HR.

**Member states can add their own employment rules.** Article 88 of the GDPR says "Member States may, by law or by collective agreements, provide for more specific rules" for processing employee data, covering recruitment, performance of the contract, management and planning of work, equality, health and safety and termination ([GDPR Art. 88](https://gdpr-info.eu/art-88-gdpr/)). In practice, Germany, France and others layer national employment and works council rules on top. If you sell into one EU country, read its rules; do not assume the GDPR text is the whole story.

**Monitoring needs a reason and a DPIA.** The ICO's guidance on monitoring workers says employers "must carry out a DPIA before undertaking any processing likely to cause high risk", "must tell workers about monitoring in a way that is accessible and easy to understand", and "must be clear about your purpose and select the least intrusive means to achieve it" ([ICO: data protection and monitoring workers](https://ico.org.uk/for-organisations/uk-gdpr-guidance-and-resources/employment/monitoring-workers/data-protection-and-monitoring-workers/)). If your product tracks activity, location, keystrokes or productivity, your customers need a DPIA and you should give them most of it.

**Health data is special category data.** Sickness absence with reasons, occupational health notes and disability adjustments are health information. The ICO has separate guidance on information about workers' health, plus guidance on keeping employment records, subject access requests for employers and draft guidance on recruitment and selection ([ICO employment guidance hub](https://ico.org.uk/for-organisations/uk-gdpr-guidance-and-resources/employment/)). Our read: in a leave tool, record "sick" by default and make the reason an optional, access-restricted field.

**Subject access requests are common in disputes.** Employees in a grievance or dismissal often ask for all the data held about them. Make it easy for your customer to export everything about one person, including notes and audit logs.

### What to build in from day one

Our checklist for an HR tool, beyond normal SaaS security:

- **Role-based access by default.** A line manager sees their team, not salaries company-wide. Payroll data, health reasons and disciplinary notes have their own permissions.
- **Audit logs.** Who viewed or changed what, and when. Employers need this in disputes.
- **Retention controls.** Delete candidate data after a set period, archive leavers, and let customers configure both. Unsuccessful candidates' data should not live forever.
- **Per-person export and deletion.** For access requests and for leavers.
- **Document handling.** Store ID documents encrypted, restrict who can download them, and record that a check happened without needing to keep every copy forever, where your customer's legal requirements allow.
- **A DPA, subprocessor list and data location statement** ready before the first sales call.
- **A one-page security summary.** Small employers do not send long questionnaires, but larger ones do. Once deals start depending on it, a SOC 2 report or a ready-made security pack becomes worth the cost.

### United States

US employee privacy is a patchwork of federal and state laws rather than one GDPR-style regime, and we have not attempted a state-by-state survey here. The rules that most directly affect HR product design right now are about automated decisions in hiring, covered next. If you handle biometric data (fingerprint or face clock-ins, for example), get specific state-law advice before launch.

## AI in hiring and people decisions: the rules that shape your roadmap

AI is the obvious feature to add to an HR product in 2026: drafting job descriptions, summarising CVs, scoring candidates, suggesting schedules, writing review summaries. Some of those are harmless. Others put you inside specific laws.

### NYC Local Law 144

New York City's Department of Consumer and Worker Protection says Local Law 144 of 2021 "prohibits employers and employment agencies from using an automated employment decision tool" unless "the tool has been subject to a bias audit within one year of the use of the tool", "information about the bias audit is publicly available", and "certain notices have been provided to employees or job candidates". The notice "must be provided 10 business days prior to use of an AEDT", and DCWP says it began enforcement on 5 July 2023 ([NYC DCWP](https://www.nyc.gov/site/dca/about/automated-employment-decision-tools.page)).

DCWP's FAQ describes an AEDT as a computer-based tool that uses machine learning, statistical modelling, data analytics or artificial intelligence, helps employers or employment agencies make employment decisions, and substantially assists or replaces discretionary decision-making. It also says "A vendor can have an independent auditor do a bias audit of its tool", and that an audit can use historical data from multiple employers using the same tool, with limits on when an employer can rely on it ([DCWP FAQ](https://www.nyc.gov/site/dca/businesses/faq-automated-employment-decision-tools.page)).

The legal duty falls on the employer, not on you. Our read: in practice it falls on you commercially, because any NYC employer using a screening or ranking feature will ask for your audit. If you sell an ATS with AI ranking, either budget for an independent audit before you market it in New York, or design the feature so it does not substantially assist or replace the decision (for example, summaries a human reads rather than scores that filter people out). Get legal advice on which side of the line your feature sits.

### The EU AI Act

Annex III of the EU AI Act lists, as high-risk, "AI systems intended to be used for the recruitment or selection of natural persons, in particular to place targeted job advertisements, to analyse and filter job applications, and to evaluate candidates", and AI systems used "to make decisions affecting terms of work-related relationships, the promotion or termination of work-related contractual relationships, to allocate tasks based on individual behaviour or personal traits or characteristics or to monitor and evaluate the performance and behaviour of persons in such relationships" ([AI Act Annex III](https://artificialintelligenceact.eu/annex/3/)).

That covers a lot of HR tech: CV filtering, candidate scoring, AI-driven task allocation in shift tools, and performance monitoring. After the Digital Omnibus amendments, Article 113 as shown on the European Commission's AI Act Service Desk says the high-risk chapters apply "from: (i) 2 December 2027 as regards AI systems classified as high-risk pursuant to Article 6(2) and Annex III" ([AI Act Service Desk, Article 113](https://ai-act-service-desk.ec.europa.eu/en/ai-act/article-113)).

Our read: 2 December 2027 is close in product terms. If you plan to sell AI screening or performance scoring into the EU, high-risk obligations (risk management, data governance, documentation, human oversight and more) are a large engineering and paperwork project for a solo founder. Many bootstrapped HR products will be better off keeping AI to drafting and summarising, with people making the decisions, until they can afford a proper compliance programme.

### Design rules we would follow

1. **Keep a human in every decision.** Draft, summarise and suggest. Do not auto-reject, auto-rank or auto-schedule people without a person approving.
2. **Never use protected characteristics or obvious proxies.** Strip names, photos, ages and addresses from anything a model scores, and test for disparate outcomes.
3. **Log what the AI suggested and what the human decided.** Employers need this if a decision is challenged.
4. **Tell candidates and employees.** Give customers plain-English notice text they can paste into job adverts and policies.
5. **Contract for no-training.** Use model providers' business terms that exclude customer data from training, and say so in your DPA.

## Integrations: your biggest cost and your best channel

HR tools rarely survive on their own. The employee list lives in payroll or the HRIS, the team chats in Slack or Teams, and the finance team lives in accounting software. If you make customers type employees in twice, they churn.

### Direct integrations vs unified APIs

Unified APIs promise one integration that connects you to dozens of HRIS and payroll systems. They are excellent products, but look at the published prices before you plan around them.

| Provider | Published price | What it covers | Source |
|---|---|---|---|
| Merge (Launch plan) | 3 production linked accounts free, then $650 a month for up to 10, $65 per linked account beyond 10 | Unified API; Professional and Enterprise are contract-priced | [Merge pricing](https://www.merge.dev/pricing) |
| Finch (Starter) | $65 per connection per month, up to 15 connections | 24 providers, read-only, for employers with fewer than 500 employees; Pro and Premier quote-only with 250+ providers | [Finch pricing](https://www.tryfinch.com/pricing) |
| Kombo | No published prices | Says pricing combines "a fixed annual platform fee" with a "variable per-customer fee" | [Kombo pricing](https://www.kombo.dev/pricing) |

Now do the arithmetic. If you charge a small employer $49 a month and each customer costs $65 a month as a Finch connection, you lose money on every integrated account. With Merge, 20 linked accounts cost $650 + (10 × $65) = $1,300 a month, which is still $65 per account, more than a $49 product's whole price. This is our illustration from the published rates, not a statement about any customer's real bill.

Our read on when to use which:

- **Under about $200 a month per customer:** build one or two direct integrations with the systems your segment actually uses (ask in every interview), plus CSV import. Many payroll and HR providers have public APIs or partner programmes.
- **Mid-market customers who each use a different HRIS:** a unified API starts to make sense, and you can price an "HRIS sync" add-on that covers it.
- **Pre-launch:** use the free linked accounts on Merge's Launch plan to test demand for a given integration before building it directly.

Our general process for choosing and approaching partners is in [how to find integration partners for a SaaS](https://zeroraised.com/blog/how-to-find-integration-partners-for-a-saas).

### Marketplaces that double as distribution

**Slack Marketplace.** For leave, 1:1, recognition and survey tools, Slack is where the team already is. Slack's guidelines say apps are unsuitable for listing if they "are installed on less than 10 active workspaces and have less than 20 monthly active users", and that "Active workspaces are workspaces that have been used in the past 28 days". Its security requirements include storing tokens securely, using the OAuth state parameter and TLS 1.2 or later, and Slack "may also perform an advanced security review at any point after an app is submitted" ([Slack Marketplace guidelines](https://docs.slack.dev/slack-marketplace/slack-marketplace-app-guidelines-and-requirements)). Our read: get your first ten workspaces through direct sales before you apply. Vacation Tracker began life inside Slack and later grew with Microsoft Teams, so building for both chat platforms is a real channel.

**Gusto.** Gusto is a US payroll and HR provider for small businesses, which makes its integrations a natural channel for US-focused HR tools. Its developer docs say a good fit is "a software product serving businesses, building an integration for customers you and Gusto share", with a use case mapping to supported categories including "ATS, performance, time tracking". It is explicit that "Early-stage products still establishing a track record of serving small businesses" are not currently supported, and that you need Production Pre-Approval before getting a Partner Checklist and production keys ([Gusto App Integrations docs](https://docs.gusto.com/app-integrations/docs/introduction)). Our read: plan for Gusto as a year-one or year-two channel, after you have customers to point to.

**Xero App Store.** If your buyers are small businesses that run their books on Xero, its app store is worth a look. Xero publishes certification checkpoints that app partners work through before listing ([Xero certification checkpoints](https://developer.xero.com/documentation/xero-app-store/app-partner-guides/certification-checkpoints)). Its listing tiers and commercial terms changed in 2026, so read the current [Xero Developer FAQ](https://developer.xero.com/faq) before planning around a listing.

**Payroll and HR platforms' own marketplaces.** Breathe, BambooHR, Deputy and others run partner or marketplace pages. If your tool complements one of them for a specific vertical, ask about a listing; you become a reason for their customer to stay.

## Pricing models small employers understand

HR software is sold in four main units: per employee, per user (often the same thing), per location, or per business by headcount band. Here is what real vendors publish, checked 12 Nov 2026.

| Vendor | Category | Published price | Unit | Source |
|---|---|---|---|---|
| BambooHR | HRIS | Core $10, Pro $17, Elite $25 on plan cards; FAQ lists flat $250, $425 and $650 a month for companies with 25 or fewer employees | Per employee per month, or flat for small teams | [BambooHR pricing](https://www.bamboohr.com/pricing/) |
| Breathe | HR for UK SMEs | £24 (1 to 10 people) up to £579 (151 to 200 people), excluding VAT | Per business per month, by headcount band | [Breathe pricing](https://www.breathehr.com/en-gb/hr-software/hr-software-prices) |
| Factorial | HR platform | "starts at $8 per month, per user"; tailored quotes | Per user per month | [Factorial pricing](https://factorial.com/pricing) |
| Homebase | Scheduling and time for hourly teams | Basic $0 (1 location, up to 10 employees), Essentials $30, Plus $70, All-in-One $120 | Per location per month | [Homebase pricing](https://www.joinhomebase.com/pricing) |
| When I Work | Shift scheduling | Essentials $2.50, Pro $5, Premium $8; Enterprise custom | Per user per month | [When I Work pricing](https://wheniwork.com/pricing) |
| Deputy | Shift scheduling | Lite $5, Core $6.50, Pro $9 | Per user per month | [Deputy pricing](https://www.deputy.com/pricing) |
| Workable | Applicant tracking | Standard $299 a month on monthly billing; Premier $599 and Enterprise $719 a month billed annually | Per company per month | [Workable pricing](https://www.workable.com/pricing) |
| Lattice | Performance and engagement | Performance $10, Goals and OKRs $8, Engagement $4 | Per seat per month, billed annually | [Lattice pricing](https://lattice.com/pricing) |
| 15Five | Performance and engagement | Engage $4, Perform $11, Total Platform $16 | Per user per month, billed annually | [15Five pricing](https://www.15five.com/pricing) |

Details worth noticing:

- **BambooHR now shows prices,** although each plan still has a "Get Quote" button and add-ons such as payroll and benefits are quote-based. Its FAQ lists slightly different figures for Core ($10.25) and Pro ($17.50) than the plan cards, and the page does not explain the difference.
- **Breathe prices per business, not per person.** Its page says the subscription is "per business account and not per person", includes a 14-day free trial with no card, and says annual plans save about 15% on the lower tiers.
- **Deputy added a floor.** Monthly Lite, Core and Pro plans have a minimum spend of $30 per month per invoice from 1 September 2025, and annual billing saves 10%.
- **When I Work** offers a 14-day trial with no credit card, and its FAQ ties the $2.50 rate to single-location teams.
- **Homebase** shows a "Save 20%" annual toggle but lists one price per plan without saying which billing cycle it is.
- **Lattice** has a $4,000 minimum annual agreement. **Workable** offers a 15-day trial with no card.

### Which model to use

Our read, building on our [per-seat vs flat-rate pricing guide](https://zeroraised.com/blog/per-seat-vs-flat-rate-pricing-for-saas):

- **Per business by headcount band.** Easiest for a small employer to approve, because the price does not change each time they hire someone. Breathe's bands are a good model. Our pick for most bootstrapped HR tools selling to businesses under 100 people.
- **Per location.** Natural for multi-site hourly businesses (restaurants, clinics, retail), where the owner thinks in sites. Homebase uses it.
- **Per employee or per user.** Matches how bigger HRIS and scheduling tools charge, scales with the customer, and is easy to compare. It is also easy to compare unfavourably: at $2.50 per user, you are competing with When I Work on price.
- **Per hire or per job slot.** Common in recruiting. Works for vertical ATS products where hiring is seasonal.

Two warnings. First, per-employee pricing in sectors with high turnover and many part-timers (hospitality, care) creates arguments about who counts; define "active employee" in your terms. Second, very low per-user prices leave no room for integration costs or support, as the unified API arithmetic above shows.

Worked comparison (our arithmetic from the published rates): a 40-person UK business would pay Breathe £99 a month on the 21 to 50 band. The same 40 people on BambooHR's Pro card rate of $17 would be $680 a month, although BambooHR's flat small-team pricing only applies up to 25 employees. Different products, different scope, but it shows how widely buyers' price expectations can vary. Ask your interviewees what they pay before you set a number.

## Bootstrapped HR tech examples (with primary sources)

We only include companies whose own site or founders state how they were funded.

**Vacation Tracker (leave management).** The company's blog post on its history says the founders built it inside their consulting business, Cloud Horizon: "We used profits from Cloud Horizon to create Vacation Tracker." It says "In April 2018, they finally launched", that the first version lived inside Slack, where "Slack only allowed five buttons per row, so they created a calendar with buttons representing only workdays", and that "During COVID, companies rushed to Teams". On funding: "They never raised external funding." On results: "Seven years later, Vacation Tracker is approaching $3M ARR." On channels: "Content marketing became their most effective channel, while LinkedIn completely flopped despite multiple attempts." It also lists "Waiting too long to experiment with pricing and packaging" as a mistake ([Vacation Tracker blog, updated 17 Aug 2026](https://vacationtracker.io/blog/0-to-3m-arr-how-two-bootstrapped-founders-built-vacation-tracker-and-brought-in-a-100m-ceo/)).

Our read: three lessons for a bootstrapper. Fund the early product from a services business if you can. Build inside the tool your users already open every day. And treat platform shifts (Slack to Teams) as growth waves to ride, not threats.

**Pinpoint (applicant tracking).** Pinpoint's careers FAQ says: "We bootstrapped to 500 customers and £5M ARR before raising private equity in 2023, and more than 1,000 companies now hire on Pinpoint." It adds that "The 2023 investment bought ambition, not a burn rate" ([Pinpoint careers FAQ](https://workwithus.pinpointhq.com/faqs)).

Our read: Pinpoint shows the order of operations that suits a bootstrapper in a category many assume needs VC. Build a product companies pay for, get to meaningful revenue, and only then decide whether outside money buys you anything. If you do later want capital without the venture model, our list of [ways to fund a product without venture capital](https://zeroraised.com/blog/ways-to-fund-a-product-without-venture-capital) covers revenue-based financing, grants, pre-sales and growth equity that targets bootstrapped companies.

## Distribution: how bootstrapped HR tools get customers

### Direct outreach in one vertical

The most reliable early channel is still one-to-one. Pick one industry and one region, list 200 employers from industry directories, association member lists and local business listings, and reach out about one specific problem. Our full process is in [how to sell B2B SaaS as a solo founder](https://zeroraised.com/blog/how-to-sell-b2b-saas-as-a-solo-founder). For HR, lead with the cost of the current mess (a missed shift, a holiday pay error, a candidate lost to a slow process), not with features.

### HR consultants and accountants

Small employers often outsource HR to a consultant and payroll to an accountant or bookkeeper. Both talk to many small employers each month and get asked "what software should we use?" Breathe, for example, says "Breathe's free Partner Programme is built for UK HR consultants supporting SMEs" ([Breathe partners](https://www.breathehr.com/partners/accredited-hr-partners)). Our read: build a partner programme early with a simple revenue share or a discount for their clients, a partner dashboard to see client accounts, and a co-branded onboarding guide. Ten active consultants can be your whole sales team in year one.

### Free tools and templates for SEO

HR people search for practical help: job description templates, offer letter templates, holiday entitlement calculators, rota templates, onboarding checklists, interview question lists, policy templates. Each is a page that can rank and a natural lead-in to your product. Vacation Tracker says content marketing became its most effective channel. Our read: build calculators and templates for your specific vertical ("care home rota template", "restaurant holiday pay calculator UK") rather than generic HR content, where the big platforms already rank.

Be careful with templates that look like legal advice. Add clear "check with an adviser" notes, and have an HR or employment law professional review anything that states rules.

### Marketplaces

Covered above: Slack, Microsoft Teams, Gusto, Xero, and the partner pages of HR and payroll platforms. Each listing is a permanent source of qualified installs once you clear the entry bar.

### Launches and communities

Launch sites, HR communities and industry groups bring early users and feedback. Our [product launch checklist for bootstrapped makers](https://zeroraised.com/blog/product-launch-checklist-for-bootstrapped-makers) covers the sequence. For HR tools, line up two or three customer testimonials from your target vertical first; a care home manager trusts another care home manager more than a ranking on a launch site.

## Worked example: a rota and compliance tool for small care agencies

This is an illustrative model with our own numbers. It is not data from a real company.

**Product:** shift scheduling for small UK home care agencies that checks each carer's training certificates and right-to-work expiry before they can be assigned, with a simple mobile app for carers and CSV export to payroll.

**Pricing (ours), per agency by headcount band:**

- Small: £79 a month, up to 25 carers
- Medium: £149 a month, 26 to 60 carers
- Large: £249 a month, 61 to 120 carers
- Annual plans: two months free

**Assumptions for month 12 (ours):**

| Item | Number |
|---|---|
| Small agencies | 40 |
| Medium agencies | 20 |
| Large agencies | 6 |
| Share of revenue paid annually | 30% |

**Revenue arithmetic:**

- Small: 40 × £79 = £3,160 per month
- Medium: 20 × £149 = £2,980 per month
- Large: 6 × £249 = £1,494 per month
- List MRR: £3,160 + £2,980 + £1,494 = **£7,634**

Annual customers pay 10 months for 12, so their effective monthly price is about 83% of list. If 30% of revenue is annual:

- Effective MRR ≈ £7,634 × (0.70 + 0.30 × 10/12) = £7,634 × 0.95 = **about £7,250**

**Monthly costs (ours, illustrative):**

| Cost | Per month |
|---|---|
| Hosting, database, backups, file storage | £150 |
| SMS and push notifications to carers | £150 |
| Email, auth, monitoring | £80 |
| Insurance (cyber and professional indemnity, amortised) | £200 |
| HR or care compliance adviser retainer | £300 |
| Partner commissions (consultants) | £400 |
| Tools, domain, misc | £70 |
| **Total** | **£1,350** |

That leaves roughly £5,900 a month before your own salary and tax, from 66 agencies. Note what is not in the cost table: a unified API. Finch's Starter plan caps out at 15 connections, and even at its $65 per connection rate, 66 connections would be 66 × $65 = $4,290 a month, a large slice of roughly £7,250 in revenue. That is why this model uses CSV export to payroll first, and adds direct integrations with the two or three payroll systems agencies mention most.

What would break the model: trying to serve every type of care provider at once, a carer's certificate expiring unnoticed because of a bug, a data breach involving identity documents, or slow onboarding that keeps agencies on paper. Those are the risks to manage, more than competition.

## Decision table

| Your situation | Our recommendation |
|---|---|
| You ran HR, ops or scheduling in one industry | Build the tool you wished you had for that industry; your old network is your first ten customers |
| You are a developer with no HR background | Partner with an HR consultant or practitioner (equity or paid adviser) before writing code |
| Your idea ranks or filters candidates with AI | Keep a human deciding, budget for an NYC bias audit if you sell there, and plan for EU high-risk rules from 2 December 2027 |
| Your idea monitors employee activity | Expect customers to need DPIAs; make the least intrusive option the default |
| Your price is under about $200 a month per customer | Direct integrations and CSV import, not a unified API on every account |
| Your customers already live in Slack or Teams | Build there first; apply to the Slack Marketplace after 10 active workspaces |
| You sell to US small businesses on Gusto | Plan a Gusto integration once you have a track record; it is not open to early-stage products |
| You want to raise later | Get to revenue first; Pinpoint raised after bootstrapping to £5M ARR |

## A 90-day plan

### Days 1 to 30: wedge and evidence

1. Choose one HR job (leave, scheduling, onboarding, hiring, 1:1s) and one industry and country.
2. Interview 15 to 20 people who do that job and 5 who pay for it. Ask to see their current spreadsheet, rota or folder.
3. Write down the costliest failure in their current process, in their words.
4. List every system they already use (payroll, HRIS, chat, accounting). Pick the one or two you must integrate with.
5. Ask 5 employers for a paid pilot or pre-payment. If nobody pays, change the problem, not the pitch.

### Days 31 to 60: build the narrow version

1. Build the smallest tool that removes that failure for one type of employer.
2. Ship the data basics: role-based access, audit log, per-person export and deletion, retention settings, a DPA and a subprocessor list.
3. If you use AI, keep it to drafting and summarising with human approval, and write the notice text customers will need.
4. Build CSV import and one direct integration with the system your pilots use most.
5. Onboard pilot customers yourself, on calls, and watch the first week of real use.

### Days 61 to 90: sell and distribute

1. Convert pilots to paid plans and ask each happy customer for a testimonial and an introduction.
2. Recruit three HR consultants or accountants in your vertical as partners.
3. Publish two free templates or calculators for your vertical.
4. Start outreach to 200 employers in your segment with a short, specific message.
5. Launch publicly once you have three testimonials, and track which channel each paying customer came from.

## Common mistakes

- **Building an all-in-one HR platform.** You will be compared with tools that have had years and large budgets. Pick one job.
- **Selling to "SMBs" in general.** A software agency and a care home have different HR problems. Pick an industry.
- **Underpricing per user.** A few dollars per employee leaves no room for support, integrations or insurance.
- **Ignoring the employee as a user.** The employer buys, but staff use the mobile app. If carers or waiters hate it, managers churn.
- **AI that decides about people.** Auto-rejecting candidates or auto-scoring staff brings bias audit and high-risk AI obligations you probably cannot afford yet.
- **Treating health and ID data like any other field.** Restrict, encrypt, log and delete it on schedule.
- **Assuming the integration is a weekend job.** Payroll and HRIS integrations have edge cases (leavers, rehires, multiple pay schedules). Budget weeks, not days.

## Frequently asked questions

### Can you start an HR tech startup without VC funding?

Yes, if you pick a narrow problem for small employers and charge from the start. Vacation Tracker, a leave management tool that began as a Slack app, was funded from its founders' consulting profits, never raised external funding and says it is approaching $3M ARR. Pinpoint, an applicant tracking system, says it bootstrapped to 500 customers and £5M ARR before raising private equity in 2023. What usually needs outside money is full HRIS and payroll, where compliance and switching costs are high.

### What HR tech ideas are easiest to bootstrap?

Tools that one manager can buy without a procurement process: leave and absence tracking, shift scheduling and swaps for one industry, onboarding checklists and document collection, interview scheduling, an applicant tracker for one vertical such as clinics or restaurants, 1:1 and check-in tools, and pulse surveys. Our read: the best wedges sit next to a system the customer already uses, such as Slack, Microsoft Teams, Gusto or Xero, so you can sell through that system's marketplace.

### Do I need a bias audit to sell an AI hiring tool?

If your customers use it in New York City and it counts as an automated employment decision tool, yes in practice. NYC Local Law 144 prohibits employers and employment agencies from using such a tool unless it has had a bias audit within one year of use, the audit information is public and candidates get notice 10 business days before use. DCWP's FAQ says a vendor can have an independent auditor audit its tool. In the EU, AI used for recruitment or worker evaluation is listed as high-risk under the AI Act. This is not legal advice.

### How should I price HR software for small businesses?

Match how your buyer already pays. Scheduling tools usually charge per user per month (When I Work $2.50 to $8, Deputy $5 to $9), performance tools per seat (15Five $4 to $16 billed annually), and some HR platforms per business by headcount band (Breathe from £24 a month for 1 to 10 people). Our read: for a bootstrapped tool, a flat price per company or location with headcount bands is easiest for a small employer to approve, with a per-employee rate above a ceiling.

### Should I use a unified API like Merge or Finch for HRIS integrations?

Only when your price can carry it. Merge's Launch plan includes 3 free production linked accounts, then costs $650 a month for up to 10 and $65 per extra account. Finch's Starter plan is $65 per connection per month. Kombo does not publish prices. Our read: if your product costs under about $200 a month per customer, build one or two direct integrations with the systems your segment uses most, and add a unified API when larger customers ask for many systems.
