Vlad Matsiiako
Vlad Matsiiako is the Ukrainian-born co-founder and CEO of Infisical, the open-source secrets, certificate, and access management platform that processes well over 100 million secrets a day. After studying in the Netherlands, working as one of the first data scientists at bunq, picking up a master's at Cornell, and a stint at Figma, he teamed up with two Cornell friends, cycled through ideas like a VR marketplace, and finally bet on the unglamorous problem that bites every engineer: leaked API keys and sprawling .env files. Infisical went through Y Combinator's Winter 2023 batch, open-sourced its code to earn developer trust, and raised a $16M Series A led by Elad Gil in 2025.
