Best Corporate Card for Bootstrapped Startups (2026)

Most startup corporate cards underwrite on your cash balance or your investors, not your personal credit. Ramp asks for at least $25,000 in a linked US bank account and Brex quotes a $50,000 minimum for startups that have raised. If you are bootstrapped with a thin balance, a Mercury IO card or a classic bank card such as Amex Blue Business Cash is usually the realistic first card.

Key takeaways

  • The bootstrapped question is eligibility, not rewards: Ramp requires at least $25,000 in cash in a linked US business bank account, and Brex says it requires $50,000 as a minimum cash balance for startups that have raised.
  • Mercury IO has no credit check, no personal guarantee and no annual fee, pays 1.5% cashback, and sets limits from your Mercury balances, but you must bank with Mercury first.
  • Amex Blue Business Cash pays 2% cash back on the first $50,000 of eligible purchases each calendar year, then 1%; Capital One Spark Cash Plus pays 2% flat with a $150 annual fee and no foreign transaction fees.
  • Corporate cards from Ramp, Brex, Mercury and Rho do not need a personal guarantee. Bank-issued small business credit cards weigh your personal credit, so you carry more of the risk.
  • Outside the US, most founders start with a business debit card (Wise, Tide, Airwallex) and watch the FX fee, for example Tide charges 2.75% on international card payments on its free Lite plan.

Short answer: If you are a US company with less than $25,000 in the bank, the startup corporate cards you have heard of (Ramp, Brex) will probably say no, because they underwrite on cash and funding. The realistic first card is Mercury IO if you bank with Mercury (no credit check, no personal guarantee, 1.5% cashback), or a bank-issued card such as Amex Blue Business Cash (2% back on the first $50,000 a year) if you are comfortable using your personal credit. Apply to Ramp once your balance clears $25,000.

Every requirement, rate and fee below comes from the issuer's own page, checked on 12 Nov 2026. The advice in between is ours and is marked as such.

TL;DR#

  • Ramp needs a US corporation, LLC or LP, an EIN and "at least $25,000 in cash in any US business bank account linked to your application" (Ramp support).
  • Brex says "we require $50,000 as a minimum cash balance (if you've raised funding)" for startups, and needs a US EIN, US incorporation and a US physical address (Brex requirements).
  • Mercury IO has "Unlimited 1.5% cashback", no annual fee, no personal guarantee and no credit check, but only for Mercury account holders (Mercury IO).
  • Bank cards pay well if your personal credit is strong: Amex Blue Business Cash 2% to $50,000 a year, Capital One Spark Cash Plus 2% flat, Chase Ink Business Unlimited 1.5%.
  • Outside the US, start with a business debit card and compare FX fees before rewards.

Disclosure: ZeroRaised is a launch site for bootstrapped products. We have no commercial relationship with any card issuer named here and earn nothing if you apply. This is general information, not financial advice; card terms and approvals depend on your company, so read the issuer's terms before you apply.

Why bootstrapped startups get declined#

Startup corporate cards were built for venture-backed companies. Instead of the founder's credit score, they look at the company's bank balance and, often, its investors. Brex's requirements page says startups qualify for monthly payments if they have "Received an equity investment of any amount (accelerator, angel, or VC)", and its commercial segment needs "more than $500k in annual revenue" (Brex requirements). Ramp does not ask about funding, but its $25,000 cash floor does the same filtering.

Our read: pick a card in two stages. First, one you can get today without an awkward decline. Second, a spend-management card once your balance is boring enough that underwriters like you.

Charge card, credit card, debit card and personal guarantees#

Four terms decide which card fits.

  • Debit card. Spends money already in your account. No credit, no underwriting, no business credit history. Every business account gives you one.
  • Charge card. A line you pay in full each statement period. Most startup corporate cards work this way. Capital One describes Spark Cash Plus as a card "designed to be paid in full" (Capital One).
  • Credit card. A revolving line where you can carry a balance with interest. Chase's Ink Business Unlimited, for example, lists "0% intro APR for 12 months from account opening on purchases", then a variable APR (Chase).
  • Personal guarantee. A promise that you personally repay the company's card debt if the company cannot. Brex states "Brex does not require a personal guarantee" and says its cards "do not check or report to personal bureaus" (Brex card). Ramp says it "does not require founders to personally guarantee your expenses" (Ramp support). Bank-issued small business cards assess your personal credit; Capital One lists the credit level needed for Spark Cash Plus as "Excellent".

Our read: a personal guarantee is not automatically bad. On a small limit paid in full every month the practical risk is small. Just know you are signing one.

The picks#

Mercury IO: the realistic first corporate card#

Mercury's IO card is the closest thing to a startup corporate card that does not care how much you raised. Mercury says "We do not run a credit check during the IO sign-up process", lists "No personal guarantee", and says some customers are eligible immediately with no separate application. Cashback is "Unlimited 1.5% cashback on all spend", and "We don't charge annual fees on IO cards" (Mercury IO).

The catch: IO is "Exclusively for Mercury account holders" and limits are based on your Mercury balances and linked external accounts, so a small balance means a small limit. Mercury also charges an international transaction fee on non-USD IO spend; the IO page does not state the rate.

Our read: if you already chose Mercury from our business bank account guide, turn on IO and put your SaaS subscriptions on it. It is the cleanest way to get a card with no personal liability while your balance is small.

Amex Blue Business Cash: best rewards if your personal credit is good#

If your personal credit is strong and you will accept that the issuer looks at it, Amex Blue Business Cash is hard to beat for low spend. Amex says Card Members "earn 2% cash back on all eligible purchases on up to $50,000 per calendar year, then 1%", credited automatically to your statement. The application page also says you can "Know if you're approved with no credit score impact" before the full application (Amex).

Worked example (illustrative): a solo SaaS spending $1,500 a month on hosting, tools and ads puts $18,000 a year on the card. At 2%, that is $360 back, all under the $50,000 cap.

Watch foreign spend. Amex's cardmember agreement dated 30 June 2024 lists a 2.7% foreign transaction fee (agreement PDF); confirm the current rate before applying.

Capital One Spark Cash Plus: 2% with no foreign fees#

Spark Cash Plus earns "unlimited 2% cash back for your business on every purchase" and you "Pay zero foreign transaction fees" (Capital One). The $150 annual fee is refunded only in years you spend at least $150,000. Our read: worth it only above $7,500 a year in card spend (where 2% covers the fee) and with plenty of foreign-currency bills.

Chase Ink Business Unlimited: simple 1.5% and an intro APR#

Chase's card has a $0 annual fee, "Unlimited 1.5% cash back on every purchase" and a 0% intro APR for 12 months on purchases (Chase). Chase's comparison page lists a 3% foreign transaction fee for this card. Our read: do not plan to revolve card debt after the intro period.

Ramp: the upgrade once you clear $25,000#

Ramp is the card to apply for when your balance makes it possible. You need to be a registered corporation, LLC or LP (sole proprietors are not accepted), have an EIN, keep most operations and spending in the US, and have at least $25,000 in cash in a linked US business bank account. Your US address must be a physical one: Ramp rules out PO boxes, virtual office, registered agent and mail-forwarding addresses. Owners without an SSN can apply with a foreign passport and proof of address (Ramp support).

The software is the draw: the Free plan costs $0 per user per month, and Plus is $15 per user per month plus a platform fee (Ramp pricing). Ramp's pricing page says card rewards can be used to pay for Plus, but it does not state a cashback rate, so we have not quoted one.

Brex and Rho: fine later, not first#

Brex requires no personal guarantee and "does not charge foreign transaction fees", though conversions can carry an FX markup of up to 3% (Brex card). But its startup criteria are written around funding (Brex requirements). Rho also needs no personal guarantee or personal credit check, for US-incorporated businesses with an EIN (Rho); its cashback depends on plan and payment terms, so read the current terms. Our read: a bootstrapped company is not Brex's target customer. Apply only once your balance is comfortably above its thresholds.

Outside the US#

Startup corporate cards are mostly a US product. For a UK Ltd or EU company, the first card is usually your business account's debit card, so compare FX fees, not cashback.

  • Wise Business (UK): the first card on the account costs nothing, extra team cards are £3 each one-off, card spending converts at the mid-market rate with "No markups or margins" on the rate, and ATM withdrawals are free up to £250 a month, then 2.69% (Wise card fees).
  • Tide (UK): plans run from Lite (free) to Max (£69.99/m). Lite charges a 2.75% FX fee on international card payments; Smart (£12.49/m), Pro and Max show 0% (Tide pricing).
  • Airwallex (UK): Explore is £19/month, or £0 if you deposit at least £10k a month or hold £10k, and includes multi-currency company and employee cards with "zero international fees" (Airwallex pricing).

Our read: if you pay US software bills from a UK company, a 0% FX card beats any cashback you can qualify for. Revolut Business, Monzo, Starling and Pleo are also options; we could not verify their pricing pages for this post.

How to build business credit without VC#

  1. Form the entity and get an EIN. Every US corporate card above requires one.
  2. Separate finances completely. No personal spending on business accounts or cards. Our guide on how to pay yourself as a solo founder covers moving money out properly.
  3. Put recurring bills on the card and pay in full. Hosting and SaaS tools are predictable spend that builds a payment history.
  4. Let the balance grow, then reapply. Cash-underwritten limits rise with your balance, and a decline today is not a decline forever.

Frequently asked questions#

Can a bootstrapped startup get a Ramp or Brex card?#

Sometimes. Ramp's US requirements include being a registered corporation, LLC or LP, having an EIN, and having at least $25,000 in cash in a US business bank account linked to the application. Brex says it requires $50,000 as a minimum cash balance for startups that have raised funding, and it lists separate revenue thresholds for commercial customers. If your balance is below those numbers, expect a decline.

What is the easiest corporate card to get with a low bank balance?#

If you already bank with Mercury, the IO card. Mercury says it does not run a credit check during IO sign-up, does not require a personal guarantee, and sets limits based on your Mercury balances and linked accounts. Some customers are eligible immediately with no separate application. The limit will be small if your balance is small.

Do I need a personal guarantee for a business credit card?#

For cash-underwritten corporate cards, no: Ramp, Brex, Mercury IO and Rho all say they do not require one. Bank-issued small business credit cards from issuers such as Amex, Chase and Capital One assess the owner's personal credit, and you should read each card's terms for personal liability before applying.

Is a charge card different from a credit card?#

Yes. A charge card is designed to be paid in full each statement, while a credit card lets you carry a balance with interest. Most startup corporate cards behave like charge cards. Capital One's Spark Cash Plus page, for example, says the card is designed to be paid in full.

What should a UK or non-US founder use?#

A UK Ltd usually starts with a business debit card from its account provider, such as Tide, Wise or Airwallex, and adds a credit product later. A non-US founder with a Delaware C-corp should not count on Ramp or Brex: Ramp wants most operations and spending in the US and a US physical address that is not a virtual office, registered agent or mail-forwarding address, and Brex also requires US operations and a US physical address. Ramp does accept a foreign passport instead of an SSN, so a founder who does operate from the US can still apply.
