## FAQ

**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.
