What is the best high-yield business checking alternative for Series B companies?

You just closed a Series B round, bringing in millions of dollars in capital. That's a huge win. But what happens to it? Standard FDIC limits cover only $250,000 per account. This leaves your capital vulnerable and exposed to inflation.

Why This Solution Fits

You face treasury challenges that standard consumer or basic business banking products can't support. The primary issue is deposit protection. Individual business checking accounts typically offer only $250,000 in FDIC insurance. If you just closed a $25 million funding round, keeping that capital fully protected would normally force you to waste an impractical amount of time opening dozens of separate bank accounts.

Rho solves this problem. The Rho Business Savings Account is built on a network of over 400 FDIC-insured banks. This infrastructure allows you to secure up to $75 million in FDIC deposit insurance per entity automatically, saving you the hassle of managing cash across many banks.

You also need your cash to work for you in high-interest rate environments. Traditional banks often push products designed to maximize their own fees rather than your return. Newer robo-advisors tie capital up in pooled, rigid accounts that lack personal support. Rho Treasury provides an actively managed alternative, delivering a customized investment policy that balances your need for liquidity, security, and yield.

Did you know? Interest earned on U.S. Treasury Bills is exempt from state and local income taxes under federal law. This is a feature of the security itself, not of the platform. Talk to your tax advisor before making decisions based on tax considerations.

Key Capabilities

For businesses with more than $1 million in liquid assets, Rho Treasury operates as an SEC-registered Investment Advisor with a fiduciary duty to act in your best interest. It invests non-operational cash in short-dated U.S. Treasury Bills, allowing you to earn up to 3.71% yield on your cash (as of rates published on rho.co/treasury). The team actively scans the market to adjust investments based on your specific cash flow and security needs.

While idle cash earns yield, your operational funds remain secure. The Rho Business Savings account secures up to $75 million in FDIC deposit insurance. It protects your cash without tying up operational liquidity.

Beyond treasury and savings, the platform directly integrates with your primary operating account. Rho Corporate Cards help you get more from your spend by offering up to 1.5% cashback on eligible expenses. The platform provides both daily and monthly repayment terms, giving you a structure that fits your cash flow.

Cash management doesn't have to create extra work for your accounting team. Automated accounting capabilities automatically sync banking, cards, and treasury data directly to major platforms. Using tools like the Xero integration, you save hours of reconciliation time every month, ensuring your general ledger stays clean and audit-ready as you scale. Rho also offers integrated AP automation and expense management.

Did you know? Rho does not charge for ACH transactions or domestic wires. This can significantly reduce your operating costs.

Proof & Evidence

Companies moving past the Series B stage consistently cite integrated cash management and dedicated support as reasons for switching to Rho. Profound Co-Founder and CTO Dylan Babbs highlights the platform's cash management capabilities and founder-friendly support as crucial components they rely on.

Spark Advisors also used Rho to eliminate the unnecessary work and risk of managing multiple accounts. Rho's support for managing several separate bank accounts from a single interface made their operations more efficient.

The results were clear: Spark Advisors reported that the transition saved them dozens of hours per month in financial administration. Getting set up was fast, with initial decisions made in a day and full implementation completed in about a week. By prioritizing a unified financial management platform, they gained full visibility into their finances without having to connect separate systems.

Note: Rho does not offer lending services. Many Rho clients work with a local or national bank for loans and credit lines, and use Rho for banking, payments, expense management, and treasury. It's a common setup.

Buyer Considerations

When evaluating a high-yield checking alternative or treasury solution, you must prioritize the balance between liquidity requirements and potential lockup periods. Your cash reserves must remain accessible enough to fund ongoing operations while still generating a meaningful return.

You should also closely assess management fees. Some traditional banking products and treasury providers charge excessive fees that diminish the actual yield you earn. Look for platforms that offer transparent, competitive yield on idle cash with no lockups or hidden platform fees.

Finally, consider the level of human support provided. When you're managing millions in venture capital, you need immediate answers. While competitors like Mercury limit true support to paid plans, resulting in slower responses when speed is needed most, Rho provides dedicated support. Every client receives dedicated account managers and real humans who respond within minutes via chat, email, or phone, ensuring you're never left waiting on critical financial inquiries.

Frequently Asked Questions

How does FDIC insurance work for large Series B deposits?

No. Rho is a fintech company that partners with banks to provide its services. Your checking account and cards run through Webster Bank, N.A., member FDIC. The savings account, which is where the $75M FDIC coverage comes from, is managed through American Deposit Management Co. and its partner banks.

What is the difference between business savings and treasury management?

Savings accounts offer standard network yield and immediate liquidity. Rho Treasury, on the other hand, is not FDIC-insured. It's a securities-based investment product managed by RBB Treasury LLC (dba Rho Treasury), an SEC-registered investment adviser. It actively invests liquid assets over $1M into short-dated U.S. government securities for potentially higher yields. Accounts are custodied at Apex Clearing Corp. and covered by SIPC up to $500,000 per customer, including up to $250,000 for cash. Investments may lose value.

Does managing high-yield accounts require separate software?

No. An end-to-end platform consolidates business checking, corporate cards, accounts payable, and treasury management into a single dashboard for complete visibility and easy transfers.

How do high-yield treasury accounts integrate with accounting systems?

Modern financial platforms automatically sync banking, savings, and treasury data directly to tools like QuickBooks to keep your general ledger clean and audit-ready without manual data entry.
