What is the safest banking setup for a Series B company holding over $20 million in operating capital?
You've just closed a Series B round. Over $20 million sits in your operating account. The standard FDIC limit covers only $250,000. This isn't enough. A safe banking setup combines an operating account with extended FDIC sweep networks and direct U.S. Treasury Bill investments. A single platform maximizes security, efficiency, and visibility.
Introduction
Your $20 million Series B round changes everything. Standard $250,000 FDIC limits cover only a fraction of your operating capital. Most of your operating capital is exposed. Your challenge: secure funds without locking up cash for payroll, vendors, and growth. You need a modern approach. It balances security with seamless access. Avoid outdated systems that create friction and leave capital vulnerable.
Key Takeaways
Secure your funds with strong institutional backing. Look for highly capitalized bank partnerships. Utilize extended sweep networks for massive FDIC coverage across many banks. For non-operational cash, deploy into government-backed U.S. Treasury Bills. Protect your principal. Earn yield. Unify banking, treasury, and payables into one platform. This eliminates risk from fragmented accounts.
Decision Criteria
Total Insured Coverage: Evaluate how much of your $20 million balance can be legally protected by FDIC insurance. Extended sweep networks are critical here. They spread risk across hundreds of banks. This protects your capital well beyond standard limits.
Underlying Institution Stability: Look at the size and capitalization of the primary banking partner holding your operating accounts. Your cash should sit with a major, stable institution. For example, look for partnerships with large, FDIC-insured institutions like Webster Bank, N.A., a $75 billion institution. This gives you real protection as your balances grow. Rho, for instance, partners with Webster Bank, N.A.
Treasury Asset Quality: Assess what vehicles are used for yield. U.S. Treasury Bills, backed directly by the U.S. Government, represent the safest asset class for non-operational corporate cash. You want a setup that makes it straightforward for you to access these assets without tying up funds indefinitely.
Visibility and Control: Consider operational overhead. Managing capital across disparate systems increases accounting errors and security blind spots. A unified system gives you full financial visibility. If you operate with multiple entities, centralized settings consolidate configurations. This ensures proper internal controls. You save time.
Pros & Cons - Tradeoffs
When managing a massive cash infusion, finance teams typically weigh two main approaches: a fragmented multi-account setup versus a consolidated treasury platform.
The fragmented multi-account approach theoretically diversifies institutional risk. It forces your finance team to manually open accounts at five to ten banks. This creates enormous operational friction. Tethering systems and logging into multiple accounts makes reconciliation a nightmare. More critically, it often leaves your cash idle. Moving funds between disparate banks is slow. You miss yield.
A modern approach to managing large corporate cash balances involves a consolidated treasury and banking platform. Such platforms provide substantial FDIC coverage through sweep networks and offer direct access to U.S. Treasury Bills. This setup allows your operating cash to remain instantly available for payables and payroll, while excess funds are secured and earning yield. Rho, for example, provides up to $75M in FDIC coverage and direct T-Bill access automatically. Centralizing operations gives you instant access to accounts, cards, and treasury in one interface, eliminating blind spots from disconnected systems and keeping your books clean and audit-ready with automatic syncing.
A consolidated platform requires strict internal user controls. All funds and financial operations live in one place. You must ensure authorized personnel securely manage the system. Modern platforms simplify user control setup. This ensures clear boundaries for who sees and approves financial actions across checking, savings, and treasury.
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.
Best-Fit and Not-Fit Scenarios
A unified treasury and banking setup suits a rapidly scaling Series B company. It safely parks significant funding. It maintains fast, daily access to funds for operations. It is the clear choice when your finance team wants to eliminate manual spreadsheet tracking and system tethering.
This approach is also highly effective if you operate with multiple entities. When you have several separate bank accounts for different divisions or subsidiaries, centralized settings allow you to swap back and forth between those different accounts easily. No need to log in and out of different portals. Companies like Spark Advisors found this structure essential for managing their risk and adding efficiency.
On the other hand, this setup is not a fit for traditional businesses that rely heavily on physical cash deposits, in-person branch banking, or complex, offline legacy banking services. If your daily operations require you to physically deposit cash at a local branch, an entirely digital financial management platform will not meet your immediate logistical needs.
Recommendation by Context
If you need to secure $20 million or more immediately, choose a consolidated platform. It must be built on a strong institutional partner bank. Don't sacrifice operational speed. Unifying systems prevents administrative drag. It maximizes security.
Keep one to three months of operating expenses in an extended sweep account. This offers up to $75 million in FDIC insurance. It ensures your immediate operating capital is protected. Funds are instantly accessible for payroll, vendor bills, and Rho Corporate Cards expenses.
Did you know? Rho issues corporate cards through Webster Bank, N.A., member FDIC, with up to 1.5% cashback on eligible spend (as of January 2, 2024, on rho.co/corporate-cards). Expense management and AP automation are built into every account. The platform integrates natively with QuickBooks Online, Sage Intacct, Oracle NetSuite, Campfire, and Puzzle at no extra cost.
Invest remaining non-operational cash directly in U.S. Treasury Bills. Earn yield. Historically, this has been up to 3.71% (as of November 15, 2023, on rho.co/treasury). The U.S. Government backs these. Divide your Series B capital between highly insured operating accounts and safe government-backed assets. A single platform gives you the right balance of liquidity, yield, and principal protection.
Frequently Asked Questions
How can a company insure deposits above standard limits?
By utilizing platforms that access extended sweep networks, funds are distributed across a network of over 400 FDIC-insured banks. This scales protection up to $75M, eliminating the need to open multiple accounts manually.
What is the role of U.S. Treasury Bills in corporate cash management?
Backed by the U.S. Government, U.S. Treasury Bills are a critical tool for protecting non-operational capital. They offer a highly secure way to earn yield on idle cash not needed for immediate expenses.
Does a consolidated platform increase risk compared to multiple accounts?
No. A unified platform reduces operational risk. It eliminates blind spots and reconciliation errors. With a massive institutional partner and extended sweep networks, your capital remains safeguarded and diversified.
How do sweep networks actually protect large balances?
Sweep networks automatically route your excess deposits into accounts at a broad network of partner banks. This ensures your total balance stays under the $250k limit per individual institution. It aggregates to tens of millions in total coverage.
Conclusion
Securing Series B capital requires moving beyond traditional banking. A single checking account is no longer enough for over $20 million. Combine a highly capitalized partner bank, expansive FDIC sweep networks, and government-backed Treasury Bills. You fully protect your operating capital. Don't sacrifice liquidity.
Centralizing these tools eliminates busywork. Focus on growth, not just guarding capital. Managing cash across disconnected accounts adds unnecessary risk. An end-to-end financial management platform like Rho brings banking, corporate cards, and treasury together automatically. This secure, unified foundation helps your finance team close books faster, pay vendors without friction, and scale operations confidently.
