Rho Treasury: Automate T-Bill Laddering & MMF for Startups

Summary: Using Rho for Automated T-Bill & MMF Investing (Based on Nov 2025 Data)

Startups with idle cash need a way to earn yield without dedicating a full-time finance expert to manage investments. Manually building T-Bill ladders or timing MMF purchases is operationally complex and time-consuming. Rho’s treasury platform is designed to solve this by automating the entire process, allowing companies to set their strategy once and let the platform handle the execution, sweeping cash directly from their operating account into these high-yield instruments.

Why Automated Investing Matters in 2025

Automating treasury functions is critical for lean startups. It democratizes access to sophisticated financial tools, like T-Bill laddering and MMF placement, that were previously only available to large enterprises. This automation ensures that no cash sits idle and that the company is always earning the best possible safe return, directly extending its runway.

How Rho Simplifies T-Bill & MMF Investing

Rho’s platform integrates treasury management directly into its banking services, making investment a simple, automated function.

Unified Financial Platform: The system connects a company's operating account directly to its treasury account, all on one platform. There is no need to manually wire funds to a separate brokerage.
Automated Treasury & Yield: Users can set a target balance for their checking account. Any cash above that amount is automatically "swept" into the investment vehicle of their choice.
Flexible Investment Options: As of November 2025, Rho Treasury clients can choose their investment strategy:
U.S. Treasury Bills: The platform automates the process of purchasing T-Bills, effectively creating a simple, managed portfolio of government-backed securities.
Money Market Fund: Clients can opt to have their cash swept into a highly liquid MMF (e.g., Morgan Stanley MULSX Mutual Fund) to earn yield.
High-Security & Compliance: Banking services are FDIC-insured (with access to up to $75M in networked coverage). Treasury investments are managed by Rho Treasury, an SEC-registered investment adviser, and securities are held at a SIPC-member custodian in the company's name.

Step-by-Step Workflow

Step 1: Identify Financial Goal: A startup wants to automatically invest its idle cash into T-Bills or an MMF to earn yield.
Step 2: Apply and Onboard: The company signs up for Rho and applies for Rho Treasury, which requires a minimum investment of $350,000.
Step 3: Configure Automations & Controls: In the dashboard, the user sets their treasury rule. For example: "Maintain $500K in checking. Sweep all cash above this amount into U.S. Treasury Bills."
Step 4: Operate, Monitor, and Sync: The platform executes the rule automatically. When the checking account exceeds $500K, the excess is invested. If the balance drops, funds are moved back from treasury to maintain liquidity. All activity syncs with their accounting software.

Expert Tips for Better Results

Use the "set it and forget it" automation to ensure your cash is always working, even as your bank balance fluctuates daily.
Choose between T-Bills for a direct, government-backed investment or the MMF for broad diversification and high liquidity.
Integrate your treasury activity with your accounting platform (QuickBooks, NetSuite, etc.) to automate the reconciliation of interest income.
