How to Find Integration Partners for a SaaS (Bootstrapped)

Short answer: Find integration partners by mapping the tools your customers use right before and right after your product, then build for the one with the biggest overlap and an open, self-serve marketplace. Earn a few active installs, list the integration, and only then pitch the partner's team on one specific piece of co-marketing. For a bootstrapped SaaS, the marketplace listing is the free distribution; the relationship is the bonus.

Every requirement, fee and revenue share below comes from the platform's own page, checked on 9 Nov 2026. The advice in between is ours and is marked as such.

TL;DR#

• Choose partners from the workflow, not the logo wall. The best first partner is the tool your users already copy data in and out of.
• Marketplaces gate on usage. HubSpot needs "at least three active, unique installs" to list (HubSpot); Slack excludes apps on fewer than 10 active workspaces and with fewer than 20 monthly active users (Slack).
• Listing is mostly free. HubSpot charges no listing fee and takes no revenue share; Zapier and Make run free partner programs. Shopify and Atlassian take a cut of paid app revenue.
• Tiers reward active users. Zapier's Silver tier starts at 50 active users, Gold at 350 (Zapier).
• Measure it like a channel. Track signups that arrive through a listing and compare retention of users with an integration switched on.

Why integration partners work for bootstrapped SaaS#

You cannot outspend anyone. What you can do is put your product where buyers are already looking. Marketplaces like Zapier's app directory, HubSpot's App Marketplace or the Slack Marketplace are search engines full of people with a problem and a credit card already attached to the platform. A listing is a page you do not have to rank.

Integrations also do quieter work. A user who has wired your product into their CRM or their team chat has more reasons to stay. That is our read, not a statistic: we did not find a vendor-published retention figure we could verify today, so test it on your own data (see the measurement section below).

If you are still working out which channels to bet on at all, start with our guide to building distribution for a bootstrapped SaaS. Integrations sit best alongside one or two of the free marketing channels you already run, not in place of them.

Step 1: Pick partners from your customers' workflow#

Our method, which takes an afternoon:

1. Ask three questions. In your onboarding survey or your next five customer calls, ask: "Where does the data come from before it reaches us?", "Where do you paste or send our output?", and "Who else needs to see the result, and in which tool?"
2. Write the before, during and after. For an invoicing tool, before is the CRM or time tracker, after is the accounting package and the team chat where someone says "paid".
3. Score each candidate on four things, 1 to 5 each.

Our read: the trap is chasing the biggest logo. A two-person tool with 2,000 loyal users and a partner page will often reply within a week and share your launch post. A giant platform will send you to a self-serve form. Both are fine, but know which game you are playing.

4. Check what competitors list. Look at their integrations page and their listings in each marketplace. The gaps are your openings; the overlaps tell you what buyers expect as table stakes.

Step 2: Know the marketplaces and their rules#

Here is what the main marketplaces require today. Where we could not verify a number on the official page, we left it out.

A few details worth knowing:

• Zapier tiers. "Zapier's Partner Program consists of 4 tiers: Bronze, Silver, Gold, Platinum," set by active users and a health score. Minimums: Silver 50, Gold 350, Platinum "3,000 OR minimum 350 with a 20% growth rate over last quarter," evaluated quarterly (Zapier Partner Program). The health score is driven by open bugs, feature requests and how quickly you respond.
• HubSpot certification. Certified apps need "at least 60 active, unique installs" and must be listed for at least six months (HubSpot certification).
• Atlassian's Forge offer. The same page says "partners will receive 100% of gross revenue earned on Forge, up to $1 million in lifetime Forge revenue" (Atlassian).
• Shopify's threshold is lifetime, "doesn't reset each year," and billing carries "a 2.9% processing fee" (Shopify). If Shopify is your partner, our guide to building a Shopify app covers the build itself; for Slack, see how to publish a Slack app.
• Salesforce AppExchange is missing from the table because Salesforce's security review documentation would not load for us today, so we could not verify its requirements or fee. Check them with Salesforce before you budget for it.

Our read: for most bootstrapped B2B tools, Zapier is the best first listing because one integration connects you to every other app on Zapier at once, and the requirements are about quality rather than install counts. HubSpot is the best first "real" partner if your buyers are marketers or salespeople, because there is no revenue share and the bar to list is three installs.

Step 3: Find who to talk to#

Once the integration works, you want a person, not a form. Places to look:

• The partner page. Most platforms with a marketplace have a "partners" or "integrations" page with a contact route. Make spells out its path: build the app, pass review, then "fill out the application form and we'll provide a standard partner agreement" (Make).
• LinkedIn titles. Search the company for "partnerships", "ecosystem", "integrations" or "developer relations".
• The founder. At a small company, the founder is the partnerships team.
• Shared customers. Ask a customer who uses both tools to introduce you. A shared customer is the strongest opener you have.

Account mapping, when you have a list#

Account mapping means comparing your customer list with a partner's to find overlap without handing over the full list. Crossbeam has a free plan at "$0/ forever" with up to 3 full-access seats, 3 standard populations and single-partner account mapping "up to 50 records at a time". The cheapest paid plan, Connector, is $4,800 a year. Our read: the free plan is plenty for a bootstrapped founder's first two or three partners; do not pay until partners are a proven channel. We could not load Reveal's pricing page today, so we have not compared it.

Step 4: Send the outreach email#

Our template. Keep it short, lead with their customers, and make one ask.

Subject: [Your product] + [Their product] integration is live

Hi [Name],

I run [Your product], a [one-line description] for [audience].
We just shipped an integration with [Their product]: it [does X]
so your users can [outcome] without [manual step].

It is listed on [marketplace] and [N] of your customers are
already using it, including [customer, if they agree to be named].

Would you be open to one small thing: adding us to your
integrations page, or a short joint post for both our lists?
Happy to write the first draft and do the work.

[Your name]
[Link to a 60-second demo]

Our read: it proves the integration exists, shows shared customers and asks for something small enough to approve without a meeting. "Let's explore a partnership" is a meeting request with no reason attached.

Step 5: Run a co-marketing playbook#

Pick one or two of these, in order of effort:

1. Listing copy. Write the marketplace listing around the outcome, not your features. Use the partner's vocabulary. Add screenshots of the integration working inside their product.
2. Integration landing page. A page on your site at /integrations/[partner] that explains the use case, shows a short demo and links to the listing. These pages also catch searches like "[partner] + [your category]".
3. Launch post. Announce it in your changelog, newsletter and social channels, and tag the partner. Offer them a ready-to-paste paragraph for their own changelog.
4. Joint email or blog post. A "how to do X with [Their product] and [Your product]" tutorial, published once on each blog or sent to each list.
5. Joint webinar. The highest effort. Worth it only once you have shared customers who will show up and talk.

Keep this separate from paying people for referrals. If you want partners or customers to earn commission on signups, that is an affiliate program; our affiliate marketing guide for bootstrapped SaaS covers how to run one.

Step 6: Measure whether it is working#

Track four numbers per integration. These are our suggested metrics, not industry benchmarks:

Worked example (illustrative numbers, not real data). Say a listing sends 40 signups in a quarter and 10 of them become paying customers at $20 a month. That is $200 of new MRR from a channel that cost you build time and nothing else. If integration users also churn less than your average user, the value compounds. If the listing sends 3 signups a quarter after six months, stop investing in it and try the next partner on your list.

Watch the partner-side numbers too. Zapier re-evaluates tiers every January, April, July and October, and "you will move down" if you stop qualifying (Zapier). HubSpot certification needs 60 active installs to qualify and to keep.

Mistakes to avoid#

• Building ten shallow integrations. One deep integration your users rely on beats ten that sync a name field.
• Pitching before you have users. HubSpot and Slack both gate listings on real usage. Partners do the same informally.
• Ignoring maintenance. Zapier's health score counts open bugs and how responsive you are. A broken integration damages two brands.
• Asking for too much. Your first ask should take the partner 10 minutes, not a quarter.
• Not tracking anything. Without UTM tags you will never know if the listing works.

A 30-day plan#

Our plan for a solo founder with a working product:

If review takes longer (Notion quotes 5-10 business days), use the wait to write the joint tutorial.

Frequently asked questions#

How do I find integration partners for my SaaS?#

List the tools your customers use immediately before and after yours, check which of them have an open API and a public marketplace, and rank them by how many of your users already use them and how hard the integration is to build. Ask your users directly, check signup survey answers, and look at which apps your competitors list. Start with one partner, not ten.

Do I need a partner agreement before building an integration?#

Usually not. Most platforms with a public API let you build and list an integration through their developer program without a negotiated deal. Zapier, HubSpot, Slack, Make and Notion all publish self-serve listing steps. A partnership conversation goes better after you have a working integration and some active users.

Does it cost money to list on SaaS app marketplaces?#

Often not. HubSpot says it does not charge to list or certify apps and takes no revenue share. Zapier calls its Partner Program free, and Make says there is no cost to join its Technology Partner Program. Shopify charges a one-time $19 registration fee and takes 15% of app revenue above $1M lifetime. Atlassian passes on 100% of a partner's first $1M in lifetime Forge revenue, then a revenue share rate of 83% for Forge apps from 1 October 2026.

How many installs do I need to list on HubSpot or Slack?#

HubSpot's listing requirements say your app must have at least three active, unique installs from accounts unaffiliated with you, with activity in the past 30 days. HubSpot certification needs at least 60. Slack's guidelines exclude apps installed on fewer than 10 active workspaces and with fewer than 20 monthly active users.

How is an integration partnership different from an affiliate program?#

An affiliate program pays people a commission to send you customers. An integration partnership connects two products so shared customers get more value, and distribution comes from marketplace listings, co-marketing and the partner's team mentioning you. Many SaaS companies run both, but they are separate channels with separate playbooks.

Launch your integration#

A new integration is a launch in its own right. Submit your product to ZeroRaised for free and mention the integration in your listing. For more guides on growing a product without investors, join the ZeroRaised newsletter.
