Congrats to @matsiiako, @dangtony98, @maidulll and @infisical (W23) on their $40M Series B!
Infisical is the open source security infrastructure that manages API keys, passwords, and certificates for developers, machines, and AI agents.
When an AI agent needs access to a sensitive system, Infisical hands it a fake credential and swaps in the real one through a proxy. The agent does its job without ever seeing the actual key.
More than 1,300 organizations use the platform, including Airbus, Hugging Face, and the US Government, and they just passed 30,000 stars on GitHub.
