What Grasshopper is, in 2026
Grasshopper Bank, N.A. is a US national bank chartered by the Office of the Comptroller of the Currency (OCC) built specifically for startups, venture-backed early-stage companies, and growth-stage tech firms. Founded 2019 in New York City. The structural distinction from Mercury / Brex / Bluevine / Rho is that Grasshopper IS the bank — not a partner-bank fintech operating on top of one.
Product surface: free business checking with no monthly fee or minimum balance, FDIC-insured deposits directly at Grasshopper Bank, multi-bank Cash Sweep program extending FDIC pass-through to $25,000,000, Mastercard business debit cards + virtual cards, developer API (read + write) at developer.grasshopper.bank, multi-user roles, ACH + wire infrastructure, and a Money Market product with federal-funds-rate-linked yield. Accounting integrations: QuickBooks Online, Xero, NetSuite.
An OCC-chartered US national bank, not a partner-bank fintech. Direct FDIC cover. Smaller scale than Mercury / Brex / Bluevine — but the chartered-bank licence is the structural moat.
At a glance
Who Grasshopper is for: US-incorporated startups (Delaware C-Corp, LLC, S-Corp) and growth-stage tech companies that want a chartered-bank-direct deposit relationship rather than a partner-bank fintech stack. Engineering-led founders wanting API access on the free tier (read + write, no upgrade required). Treasury teams sensitive to partner-bank counterparty risk at Mercury / Brex / Bluevine / Rho's sponsor banks.
Who to avoid Grasshopper for: startups wanting the most-polished SMB-customer UX (Mercury or Brex at far larger scale); finance teams needing deep spend-management surface (Ramp or Brex Empower); operators needing multi-currency operating accounts (Wise Business or Airwallex); pre-revenue solo founders preferring an easier underwriting path (Mercury / Bluevine / Novo onboard more aggressively at the early stage); and operators outside the US (Grasshopper does not serve non-US-incorporated entities).
Safety in one sentence: Grasshopper Bank, N.A. is an OCC-chartered FDIC-member US national bank; customer deposits are FDIC-insured directly at Grasshopper up to $250K, with the multi-bank Cash Sweep program extending pass-through to $25M for opt-in customers.
Bank structure & direct FDIC cover
Grasshopper Bank, N.A. is a US national bank chartered by the Office of the Comptroller of the Currency (OCC) and a member of the Federal Deposit Insurance Corporation (FDIC). This is the structural distinction from the partner-bank fintech category (Mercury, Brex, Bluevine, Rho, Novo, Lili, Found, Relay) — those companies operate on top of FDIC-member sponsor banks; Grasshopper IS the FDIC-member bank.
The customer-protection regime is direct FDIC insurance. Customer deposits at Grasshopper Bank are FDIC-insured up to the standard $250,000 per depositor per ownership category. Bank-failure resolution in a worst case would follow FDIC's standard receivership process — typically multi-day payout to insured depositors within the statutory window. The depositor relationship is directly with Grasshopper Bank, not mediated through a partner-bank chain.
The multi-bank Cash Sweep program extends FDIC pass-through to $25,000,000 per customer for opt-in customers. The mechanism is the same structural model as Mercury's IntraFi sweep or Brex's sweep network: enrolled balances above $250,000 are automatically distributed across a network of FDIC-insured partner banks in $250,000 buckets, so a $25M Grasshopper balance appears as roughly 100 separate $250,000 deposits at network banks, each with its own FDIC coverage. Two preconditions: the customer must opt in to the sweep program (non-sweep balances at Grasshopper alone are capped at the standard $250,000 ceiling), and the customer must monitor for partner-bank overlap with their own deposit relationships at any of the network banks.
The structural advantage versus partner-bank fintechs is the counterparty-risk profile. Mercury depends on Choice Financial Group + Evolve Bank & Trust + Patriot Bank + the IntraFi network participants all remaining solvent and FDIC-compliant. Brex depends on its sponsor banks. Bluevine depends on Coastal Community Bank. Rho depends on Webster Bank. Grasshopper depends only on Grasshopper Bank itself remaining OCC + FDIC compliant. For treasury teams modelling partner-bank counterparty risk explicitly, the chartered-bank-direct structure removes one operational link from the chain.
The fee schedule
| Item | Standard (free) |
|---|---|
| Monthly fee | $0 |
| Minimum balance | None |
| Domestic ACH (in / out) | Free, unlimited |
| Domestic wire (outgoing) | $5 flat fee |
| International wire (outgoing) | $15-25 + correspondent fees |
| FX margin on card spend | 0% (Mastercard rate) |
| Cash Sweep enrolment | Free (opt-in) |
| Money Market yield | Variable, fed-funds-linked |
| API access (read + write) | Included |
| Mastercard business debit | Included |
The pricing is structurally simpler than Mercury (Standard free vs IO $35/mo) — Grasshopper ships API write access on the free tier and includes Cash Sweep enrolment at no cost. The line items worth modelling are the international-wire fees ($15-25 plus correspondent fees, typically $40-60 total) and the Money Market yield (variable, federal-funds-rate-linked; confirm current rate in product page before treating as load-bearing for treasury policy).
Hands-on notes
Onboarding for a Delaware C-Corp or LLC clears in 2-5 business days for well-formed applications — slower than Mercury's same-day pace because the chartered-bank-level KYB / KYC is structurally heavier. Required documents: Certificate of Incorporation, IRS EIN letter, beneficial-ownership disclosure (FinCEN 25%-or-more rule), and ID for each beneficial owner. OFAC sanctions screening + BSA / AML compliance is applied at bank-level standards rather than partner-bank-passthrough standards. International founders incorporating via Stripe Atlas / Firstbase / Clerky face the same chartered-bank-level review.
The product UX is clean but materially lighter than Mercury or Brex on feature surface area. The API access is one of Grasshopper's structural strengths — included on the free Standard tier rather than gated behind a paid tier (Mercury's API write requires IO at $35/mo). Engineering-led startups building automated finance workflows (Slack notifications on outbound transfers, custom approval-routing logic, reconciliation pipelines) get full API access without upgrading.
The Cash Sweep enrolment is straightforward — opt-in checkbox during onboarding or in account settings. The sweep allocation runs in $250K buckets across roughly 100 FDIC-insured partner banks (the participating list updates quarterly). The Money Market product is the structural alternative to Mercury Treasury — the yield is variable and federal-funds-rate-linked, with the structural advantage being FDIC cover (since it's still a deposit product) rather than SIPC cover (which applies to Mercury Treasury's brokerage-held T-bill / MMF positions).
Friction points: smaller scale than Mercury / Brex means smaller community + shared-knowledge resources. The spend-management surface is lighter — no policy-engine-at-swipe equivalent to Ramp, no procurement intake-to-pay. Customer support is in-app + email; phone support has variable availability. USD-only operating account; international payments via SWIFT correspondents.
Plan & tier comparison
Grasshopper ships a single Standard tier for the business-checking product — no paid-tier ladder. Monetisation is interchange + Money Market yield spread + correspondent-bank revenue on international wires.
| Feature | Standard (free) |
|---|---|
| Business checking | ✓ (no fee, no minimum) |
| Direct FDIC cover | $250K per depositor |
| Cash Sweep (opt-in) | Up to $25M FDIC pass-through |
| Money Market yield | Variable, fed-funds-linked |
| Mastercard business debit + virtual cards | Included |
| API access (read + write) | Included |
| Multi-user roles | Included |
| Accounting integrations | QBO, Xero, NetSuite |
| Domestic ACH | Free, unlimited |
Caveats
Chartered-bank onboarding is structurally heavier. 2-5 business days for well-formed applications versus Mercury's same-day pace. The trade-off for the chartered-bank licence is a more demanding KYB / KYC review.
Lighter spend-management surface. No policy-engine-at-swipe like Ramp. No procurement intake-to-pay. For finance teams needing those features, pair Grasshopper with Ramp (or use Brex / Rho for paired card + cash + spend).
USD-only. No multi-currency operating account. For material non-USD flows, stack Wise Business or Airwallex alongside.
Smaller scale. Less paved YC-cohort onboarding path than Mercury. Smaller customer base means smaller shared-knowledge community for startup-banking patterns.
$25M sweep ceiling below Rho ($75M). For operators with operating-cash above $25M, structure across multiple banking relationships. Rho's larger sweep ceiling combined with Webster Bank chartered-bank partner is the structural alternative; Grasshopper's smaller ceiling with its own OCC charter is the simpler counterparty-risk structure.
Grasshopper vs. Mercury vs. Rho
Grasshopper vs. Mercury. Mercury is the partner-bank fintech with the largest US startup customer base (~200K business customers), $5M IntraFi sweep, Mercury Treasury (T-bill / MMF via Apex Clearing brokerage), and the most-polished SMB-customer UX. Grasshopper is the OCC-chartered direct alternative with $25M Cash Sweep, FDIC-only Money Market (vs Mercury Treasury's SIPC-protected investment regime), and API write access on the free tier (vs Mercury IO at $35/mo). For startups prioritising the chartered-bank licence and FDIC-only yield, Grasshopper. For startups prioritising scale, polish, and Treasury yield, Mercury.
Grasshopper vs. Rho. Rho ships a $75M Treasury sweep via Webster Bank partner-bank model with multi-entity consolidation as first-class product. Grasshopper ships $25M Cash Sweep with direct OCC + FDIC chartered-bank status. For multi-entity holding-company finance, Rho. For single-entity startups prioritising the chartered-bank licence and counterparty-risk simplicity, Grasshopper. Both are structurally distinct from Mercury — Rho via partner-bank-with-deeper-sweep, Grasshopper via chartered-bank-direct.

Who Grasshopper is for
Use Grasshopper if you are a US-incorporated startup or growth-stage tech company that prioritises the chartered-bank-direct deposit relationship over the larger scale + product polish of Mercury / Brex. The structural fit is engineering-led founders wanting free API write access, treasury teams modelling partner-bank counterparty risk explicitly, and startups whose operating-cash treasury policy is sensitive to the operational fragility of multi-party BaaS stacks (the 2024 Synapse collapse + Evolve ransomware events made this structural concern materially more concrete for many YC founders).
Use Mercury if scale, polish, and the YC-cohort default-status matter more than the licence chain. Use Rho if multi-entity holding-company finance is the structural problem. Use Brex if you want the consolidated card + cash + spend stack with the VC-backed cohort onboarding paved. Use Bluevine if 2% APY on the operating balance is the deciding factor. Pair Grasshopper with Ramp for the corporate-card + spend-management layer if procurement depth matters. Use a chartered direct bank (Chase Business, Bank of America Business) if you need branch banking, cash deposit, or commercial real estate lending — none of the US SMB neobanks cover those needs at the chartered-bank-direct level except possibly Grasshopper, and even Grasshopper is digital-only.

La cobertura FDIC por transparencia (pass-through) se aplica por banco socio, no por fintech. Si mantiene fondos en varias fintechs tipo Chime que comparten el mismo banco socio, su límite FDIC de 250.000 $ se agrega entre esos saldos. Las tenencias cripto, el efectivo de corretaje a la espera de inversión y las líneas de protección por sobregiro NO están aseguradas por la FDIC — verifique el tipo de producto antes de asumir cobertura. Reg E otorga derechos de responsabilidad limitada por transferencias electrónicas no autorizadas notificadas dentro del plazo legal.
