Open-source secrets platform Infisical raises a $40M Series B at a $600M valuation, led by Elad Gil

Infisical said on October 27 it raised a $40M Series B at a $600M valuation, led by Elad Gil with Y Combinator and Gradient participating. It offers open-source secrets, access and certificate management, says it serves 1,300+ organizations and has 30,000+ GitHub stars, and will put the money into security infrastructure for AI agents.

Why it matters

As companies let AI agents touch internal systems, they need short-lived, scoped credentials; Infisical is betting agent access control becomes core security infrastructure. It says it is already cash-flow positive (company claim).
