Rho Alternatives in 2026: 6 Business Banking Platforms Compared on Treasury Minimums and Deposit Coverage
Rho was designed for startups, and its account requirements reflect that. Checking has no monthly fee or minimum balance, Rho doesn't publish a revenue requirement, and a company can open an account the day it incorporates. The corporate card asks for a US-incorporated business with an EIN and doesn't require a personal guarantee.
Where Rho gets harder to use is in its thresholds. Rho Treasury has a $50,000 opening minimum, and Monthly Terms on the card require $25,000 held at Rho. Checking at Rho is FDIC-insured up to $250,000, and coverage beyond that comes only through a separate savings account. A business with less than $50,000 of spare cash, or more than $250,000 sitting in one operating account, may be better served by Slash, Mercury, Ramp, Brex, Relay or Aspire.¹
Slash, a business banking platform, is listed first because its treasury account⁶ has no minimum balance. Each of the other five suits a particular kind of business. All six are measured on the same details that determine whether an account will open: which entities each platform serves, how much cash its card requires, deposit coverage, card cashback and how many accounts a business can hold.
The standard in finance
Slash goes above with better controls, better rewards, and better support for your business.
Key Takeaways
- Slash's treasury account has no minimum balance, and its checking is FDIC-insured² up to $150 million through a sweep network of partner banks.
- Rho Treasury requires a $50,000 starting balance. Checking at Rho is FDIC-insured up to $250,000, with up to $75 million through a separate savings account.
- Ramp requires $25,000 in a US business bank account, and Brex's daily card applies a funding or revenue test, with a referral path for startups working toward it.
- Relay publishes the lowest sweep ceiling of the six at $3 million, against $5 million at Mercury and $6 million at Brex.
- Aspire's US account carries FDIC protection up to $100 million and its card pays a flat 1.5% on eligible spend.
What Separates a Rho Alternative for a Company Without $50,000 to Set Aside?
Feature lists in this category read almost alike. Checking, cards, bill pay and an accounting integration show up on nearly all of them. What differs is whether the account will open for you in the first place.
For a company formed this quarter, that comes down to cash and coverage. With $20,000 in the bank you are below Ramp's minimum, and $40,000 of idle cash is short of the $50,000 Rho Treasury needs. A company with no funding, no plan to raise and under $500,000 in revenue qualifies for Brex's daily card only through a customer or partner referral.
Coverage starts to matter the day a round closes. The standard FDIC limit is $250,000 per depositor, per bank, per ownership category, so a $2 million seed round held at one bank has $250,000 insured. A sweep network spreads the balance across partner banks to insure more of it, and the published ceilings below run from $3 million to $150 million.
- Entities served. LLCs, C-Corps and S-Corps, and whether sole proprietors can open an account.
- Cash to qualify for the card. None, a flat threshold, or a funding test.
- Treasury minimum. Whether idle cash earns yield from the first dollar or only above a set amount.
- Deposit coverage. How much of the balance is FDIC-insured through a sweep network.
- Card cashback. A published rate, or one set after approval.
- Account count. How many separate accounts a business can open for payroll, taxes and operating spend.
1. Slash: Best Overall for Startups Below Rho's Treasury Minimum
A startup below Rho's $50,000 line can start earning yield on idle cash in Slash from its first deposit, because the treasury account has no minimum balance. The account is backed by money market funds from Morgan Stanley and BlackRock, and its yield moves with the market. Checking deposits are FDIC-insured up to $150 million through a sweep network of partner banks. More than 10,000 businesses use Slash, which raised a $100M Series C at a $1.4B valuation led by Ribbit Capital in April 2026.
What an Early-Stage Company Gets
- No published revenue requirement. Slash's eligibility page lists no revenue minimum, and approval is at Slash's discretion.
- A card with no cash threshold. The Slash Visa® Platinum Card publishes no minimum. Its effective limit is the lower of a risk-based maximum and the funds you have on deposit.
- Unlimited virtual accounts. Each one receives deposits on its own account and routing numbers, and there is no cap on either plan, so payroll, tax reserves and a single vendor can each have their own.
- Unlimited virtual cards. Issue one per vendor or subscription, each with its own spend limit and merchant restriction, so a free trial can be kept from renewing at full price.
- Coding before the ledger. Card and bank transactions are categorized in Slash before they sync to QuickBooks Online, Xero, Sage Intacct or NetSuite through its accounting integration.
- Payments from the same balance.Bill Pay routes invoices for approval before they are paid, and transfers go out by ACH, SWIFT, RTP or FedNow.

What It Costs
Slash publishes both plans and their transfer fees on its pricing page, so you can budget the account before you apply. Free is $0 a month with up to 1.5% cashback on the card, same-day ACH at $1 and domestic wires at $6.
Pro is $25 a month with up to 2% cashback and $0 on same-day ACH, domestic wires and outgoing FedNow and RTP. Treasury works the same way on both plans, with no minimum to start.
2. Mercury: A Fit for Startups That Want Free USD Wires
Mercury keeps the everyday costs at zero. Checking has no monthly fee, and USD international wires are free on the standard option, or $15 on the option that makes it more likely your recipient gets the full amount. Deposits are eligible for up to $5 million in FDIC coverage through partner banks' sweep networks. The paid plans are Plus at $29.90 a month and Pro at $299 a month, both billed annually.
Its IO card pays a flat 1.5% with no personal guarantee. The limit is set from the balances you hold with Mercury plus any external accounts you link, and monthly repayment opens once those balances reach $15,000.
Mercury fits a startup that sends a lot of USD wires and keeps its books in QuickBooks Online or Xero, where Mercury's enriched automations are free on every plan. Treasury is out of reach for a company below Rho's line, since Mercury Treasury needs a $250,000 balance. NetSuite users should confirm the tier before they sign up. Mercury's pricing page lists NetSuite categorizations under Pro, while its FAQ says enriched NetSuite automations start on a paid plan from $35 a month.
3. Ramp: A Fit for Startups Holding $25,000 That Want Spend Controls
Ramp's strength is control over spend. It issues unlimited cards with no personal guarantee, and its checking account is held at First Internet Bank of Indiana, with multimillion-dollar FDIC coverage through a sweep network.
To apply, Ramp asks for a corporation, LLC or LP with an EIN, at least $25,000 in a US business bank account, and most operations in the US. That suits a company that already holds that much cash and wants tight rules on every card. A company with less than $25,000 in the bank won't reach the review.
4. Brex: A Fit for Venture-Backed Startups
Brex has operated as part of Capital One since the acquisition closed on April 7, 2026. Its business account offers up to $6 million in FDIC coverage through its Vault sweep, and its card needs no personal guarantee.
The funding test is written into Brex's account requirements. Daily card payments are open to a company that has taken an equity investment of any amount from an accelerator, angel or VC, plans to soon, or earns more than $500,000 a year. A tech startup on a path to those criteria also qualifies when an existing Brex customer or partner refers it. Monthly payments for funded startups need $50,000 in cash, potentially less through certain partner referrals. Brex fits a company whose round has closed. A startup still short of the criteria gets the daily card only through a referral.
5. Relay: A Fit for Founders Running Profit First
Relay is designed for founders who budget by bank account. It splits income across named checking accounts, each with its own routing and account number, which is how the Profit First method works in practice. A business opens up to 20 checking accounts on Starter and Grow and 50 on Scale, and Relay is the one platform of the six that opens checking for sole proprietors.
Banking runs through Thread Bank with FDIC sweep coverage up to $3 million. Relay's pricing lists Starter at $0, Grow at $30 and Scale at $90 for a limited time, down from $120. Relay suits a small business that wants its budget built into its accounts. It integrates with QuickBooks Online and Xero and lists neither NetSuite nor Sage Intacct, so a startup planning a move to either will have no direct sync.
6. Aspire: A Fit for Startups Holding Several Currencies
Aspire is the pick here if you juggle a few currencies. Its US account comes with banking services from a partner bank, FDIC protection up to $100 million, and multi-currency accounts in 13 currencies. The Basic plan on its US pricing page costs $0 a month with no minimum balance, and local ACH and wire transfers are free.
The corporate card pays a flat 1.5% on eligible spend. Aspire names QuickBooks and Xero on the same pricing page, and its NetSuite integration requires a Custom Plan, so a company that expects to move to NetSuite should price that plan before it commits.

How to Choose a Rho Alternative for Your Stage
Start with the rows that decide whether an account opens, and compare features after that.
- Count the cash you hold. Under $25,000 rules out Ramp, and a company without funding or $500,000 in revenue needs a referral for Brex's daily card.
- Decide where idle cash will earn yield. Rho Treasury starts at $50,000 and Mercury Treasury at $250,000, while Slash's treasury account has no minimum.
- Size the deposit coverage to your raise. A $4 million seed round is more than the $3 million Relay covers.
- Count the accounts you will need. Relay stops at 20, or 50 on Scale, and Mercury at 100 checking and 100 savings, while Slash sets no cap on virtual accounts.
- Price the card on your real spend. At $20,000 a month in card spend, the extra half point Slash Pro can earn is worth up to $100 a month, or $1,200 a year, against the $300 a year Pro costs.
Putting a Slash Account to Work in the First Month
A company that has just incorporated needs a checking account, a card, somewhere to hold its raise and a way to pay its first vendors. Slash covers all four from one login, in roughly this order.
- Apply as the business, on the company's EIN.
- Split the raise into virtual accounts, one each for payroll, tax reserves and operating spend.
- Move the reserve into the treasury account, where the first dollar can earn yield.
- Issue a virtual card for each vendor, with its own limit.
- Connect the ledger and set mapping rules once, so each transaction arrives coded.
- Send the first invoice through invoicing, which collects by bank transfer into the same account.

Conclusion
The treasury minimum, deposit coverage and the cash needed to qualify decide a Rho alternative before any feature does. Rho starts treasury at $50,000 and its checking carries FDIC insurance to $250,000, Ramp asks for $25,000 in the bank, and Brex's daily card needs funding, revenue or a referral. Mercury fits a company that sends a lot of USD wires, Relay a founder running Profit First, and Aspire a startup holding several currencies.
Slash fits the company that wants to bank, spend and earn yield from its first deposit. Both plans are published, and the treasury account has no minimum on either one.
