Buyer's guide
What is the primary goal of a treasury management platform for a startup?
The primary goal is twofold: to protect the startup's primary asset—its cash runway—from institutional and inflation risk, and to generate a meaningful, low-risk yield on that cash to extend the runway.
How do these platforms generate yield?
They typically provide access to investment vehicles that are otherwise difficult for startups to access directly, such as U.S. Treasury Bills (T-Bills), money market funds (MMFs), and repurchase agreements (repos). They also use sweep networks to spread cash across multiple banks to maximize FDIC insurance.
How to choose
- 1.Assess your primary need: Are you looking for a simple yield-generating account or a full-suite finance platform with integrated banking, spend management, and treasury?
- 2.Verify security and insurance: Ensure the provider uses qualified custodians, offers robust FDIC/SIPC insurance coverage, and is SOC 2 compliant.
- 3.Evaluate liquidity terms: Understand how quickly you can access your funds (T+0, T+1, etc.), as runway cash needs to be available for payroll and operations.
- 4.Compare net yields: Look beyond the advertised rate to understand the net yield after all management fees (typically measured in basis points, bps).
Frequently asked questions
What is treasury management for a startup?
For a startup, treasury management is the strategic management of its cash reserves (runway) to ensure safety, liquidity, and optimal yield. It involves moving funds beyond a standard checking account into low-risk, interest-bearing instruments to protect against inflation and bank risk while earning a return.
How much yield can a startup realistically earn?
Yields are typically benchmarked against the effective federal funds rate. Startups can often earn yields closely tracking short-term U.S. Treasury Bills, which can be significantly higher than traditional business savings accounts. Net yield will be the gross rate minus the platform's fees (e.g., 10-25 bps).
Is it safe to put my startup's runway in these platforms?
Generally, yes, if you choose a reputable provider. Top platforms mitigate risk by using third-party qualified custodians (like BNY Mellon or Goldman Sachs), offering SIPC insurance on securities up to $500,000, and using FDIC sweep networks to extend insurance coverage into the millions.
What's the difference between FDIC and SIPC insurance?
FDIC (Federal Deposit Insurance Corporation) insurance protects cash deposits held at an insured bank, typically up to $250,000 per depositor, per bank. SIPC (Securities Investor Protection Corporation) insurance protects securities (like stocks, bonds, and MMFs) held at a brokerage firm, up to $500,000, in case the firm fails.
When should a startup start thinking about treasury management?
A startup should consider treasury management as soon as it has raised a seed round or has more than 3-6 months of operating expenses sitting idle in a checking account. The opportunity cost of earning near-zero interest is significant, especially with larger cash balances.
