Help your portfolio make every dollar of the raise count.

Primary partners give every portfolio company institutional-grade cash management, yield and FX from day one. Help make the money your founders raise work as hard as they do.

The platform

Every dollar of the raise, on one system of record.

From the day the round closes, portfolio companies run cash, yield, FX and payments in one place. Clear enough for a founder, deep enough for an auditor.

Built for your portcos going global.

Idle balances sweep into institutional money market funds, with allocation that respects each company's liquidity needs. Payroll is never locked up.
