Mercury alternative for startups: An honest comparison

You need a bank account for your startup. Mercury is the first name that comes up. But Mercury is banking for a company you already have. If you have not incorporated yet, or if you want payments and accounting bundled from day one, the comparison changes. This post maps it honestly.

Both looch and Mercury are financial technology companies, not banks. looch is operated by Simplicity Fintech Inc. Account services are provided in partnership with Stripe, with funds held at Fifth Third Bank N.A., Member FDIC. looch Smartcards are Visa Commercial Cards powered by Stripe and issued by Celtic Bank (source: looch.money). Mercury is also a fintech company, not a bank: its banking services are provided by partner banks Choice Financial Group and Column N.A., both Members FDIC (source: mercury.com). In April 2026 the OCC granted Mercury conditional approval to establish Mercury Bank, N.A. Conditional approval is not a license to operate. Mercury is in the bank organization phase and still needs final OCC authorization plus FDIC and Federal Reserve approvals, so for now customers continue to use the same accounts through the same partner banks (source: Mercury press release, April 27, 2026).

What Mercury is (and what it is not)

Where Mercury is strong

Mercury is a well-designed banking product built specifically for VC-track startups. It has a strong reputation in the founder community and integrates with the tools that funded startups typically use.

Its free tier has no monthly fee and no minimum balance (source: mercury.com/pricing). That is a meaningful advantage for a pre-revenue company.

For teams that need higher FDIC coverage on large balances, Mercury states it offers up to $5M in FDIC insurance through its partner banks, Choice Financial Group and Column N.A., and their sweep networks (source: mercury.com). That matters once you have raised a round and are holding significant cash.

Mercury's ecosystem integrations are real. If your accounting software, cap table tool, or investor portal already connects to Mercury, that has compounding value that a raw comparison table does not capture.

Where Mercury has gaps

Mercury does not offer company formation. To open a Mercury account, you must already have a formed US entity with an EIN. Mercury does support founders who do not have an SSN: it accepts some nonresident applicants on a case-by-case basis and can accept an ITIN in place of an SSN (source: mercury.com). What it does not do is create the company for you. You still need to find a registered agent, file with the state, and obtain the EIN through separate vendors and workflows before you bank.

Mercury does not support cash deposits and has no physical branches. Funding is by check, ACH, or wire (source: mercury.com). If your business handles physical cash, that is a real constraint.

Mercury also does not provide in-person card acceptance. You can accept customer payments through Mercury Invoicing (card and digital wallet payments are processed via Stripe, and customers can also pay by ACH, wire, or ACH debit), but there is no tap to pay or card-present checkout (source: mercury.com).

The gap Mercury does not fill: Formation to banking in one flow

Every startup banking guide in this search result assumes you already have a company. That assumption leaves out a large share of founders, particularly international founders, who are at the very beginning.

Forming the entity, getting the EIN, opening accounts, and issuing cards are typically four separate steps across multiple providers. looch closes them into a single app.

What looch Start includes

looch Start forms your entity and hands you a financially operational company. Entity options are Delaware C corp, Delaware LLC, Wyoming LLC, and Florida LLC. The all-in price is $249, which includes state filing fees and one year of registered agent service.

Filing takes one business day with the state. The EIN is obtained at formation, at no additional cost. If you do not have an SSN or ITIN, looch still gets your EIN. That path takes approximately four days (source: looch.money/start).

Formation includes the documents a VC will ask for: stock purchase agreement, IP assignment agreement, and a Section 83(b) election draft. It also includes a virtual office, which gives you a business address and mail scanning (three pieces per year, renewing at $49 per year).

That is the answer to the question many guides sidestep: yes, you can go from zero to incorporated without having an SSN. looch explicitly supports it.

What opens up after formation

Once your entity is formed, your looch financial accounts are ready. These are no-fee accounts with account and routing numbers, with funds held at Fifth Third Bank N.A., Member FDIC, and FDIC pass-through deposit insurance up to $250,000 per depositor where eligibility conditions are met (source: looch.money). looch itself and its technology partners are not FDIC-insured institutions.

Smartcards are Visa Commercial Cards powered by Stripe and issued by Celtic Bank. You issue them directly from the app. Controls include per-card daily and monthly spending limits, merchant category restrictions, GL category restrictions, weekend and auto-cancel settings, foreign transaction alerts, and the ability to block mobile wallet or manually keyed transactions. See looch's full financial stack for the complete card controls.

Payment acceptance covers cards online and in-person via tap to pay, and pay by bank via Request for Payment, where your customer approves a payment directly from their bank account with no card required. looch charges 1% (minimum $1, maximum $10) for pay by bank on inbound invoices (source: looch.money/pricing).

Card acceptance is 3.3% + 30c for online card payments and 3% + 15c for in-person tap to pay (source: looch.money/pricing). Instant payments sent with a card are 3.3% + 30c.

Real-time accounting runs in the background with automatic transaction tagging, and looch Pay is the in-app payment experience that ties acceptance to your books. AI-powered 1099 calculation and filing is built in: looch AI scans your transactions and payment methods to determine what to include. Instant 1099 filing costs $2 per filing (source: looch.money/pricing).

Payroll is coming soon, not yet live (source: looch.money/features). When it launches, the pricing shown is $35/month plus $5/month per W-2 employee (source: looch.money/pricing). Until then, do not count on payroll as an available feature.

looch vs Mercury: A side-by-side comparison

Some items in this table will favor Mercury. A higher FDIC sweep ceiling matters when you are holding cash from a fundraise. A deeper integration ecosystem matters when your whole team is already in it. The table does not hide that.

Who should use Mercury

Mercury is the right call if:

• You already have a formed US entity with an EIN and just need a business bank account
• Your investors, co-founders, or accelerator cohort are already on Mercury, and that ecosystem integration has real daily value
• You are holding a large balance and want the higher FDIC coverage a sweep network can provide (Mercury states up to $5M through its partner banks and their sweep networks)
• You want a dedicated banking product built around the VC-track startup experience
• Your primary needs are checking, wires, and treasury management, not payments or accounting

If you are already incorporated and embedded in the VC ecosystem, Mercury is a strong, legitimate product and probably the path of least resistance. This post is not arguing otherwise.

Who should use looch

looch is the right call if:

• You have not incorporated yet and want to go from idea to financially operational in a single app, without stitching together a registered agent, a formation service, and a separate bank application
• You are a foreign founder who needs an EIN without an SSN or ITIN, and you want entity formation handled at the same time as your financial accounts
• You want Smartcard spend controls, in-person payment acceptance, and built-in accounting from the same platform without adding separate subscriptions
• You need to accept payments by bank through Request for Payment in addition to card payments. See how pay by bank via Request for Payment works for small businesses
• You are a freelancer, consultant, or small business owner who wants the full financial stack under one login rather than a banking-only product

The core difference is scope. Mercury is a banking product. looch is a formation-to-banking platform. If you need both the company and the financial stack built at once, looch covers more of that path in one place.

The honest decision framework

Five questions that clarify the decision quickly.

1. Do you have a formed US entity and an EIN already? No: form your company with looch and open your accounts in the same flow. Yes: either platform is worth evaluating on other criteria.

2. Do you need to form the company and get an EIN without an SSN or ITIN? looch forms the entity and gets your EIN even without an SSN or ITIN, in approximately four days, then opens your accounts in the same flow. Mercury does not form companies, though it will open an account for some nonresident founders case-by-case once the entity and EIN exist.

3. Do you need to accept payments by bank (RfP) in addition to cards? looch Pay supports pay by bank via Request for Payment. Mercury does not offer RfP pay by bank, though its invoicing lets customers pay by card, wire, ACH, or ACH debit.

4. Do you need FDIC coverage above $250K on a large balance? Mercury states up to $5M through its partner banks and their sweep networks, which is higher than the $250,000 pass-through coverage on a looch account at Fifth Third Bank N.A. (eligibility conditions apply). If you are sitting on a large raise, this favors Mercury today.

5. Are your investors or accelerator deeply embedded in Mercury? That ecosystem has genuine network value: shared tools, faster diligence, easier integrations. If that describes your situation, Mercury is probably the easier path and the right one.

Bottom line

Mercury is a strong banking product for a startup that already exists. looch is the right choice when you need to build the company and the financial stack at the same time, especially if you are outside the US or need payments and accounting bundled in.
