In this episode, Mat Vaxelaire (Partner @ Hexa) sits down with Titouan, CTO and co-founder of Dotfile (HX21), a startup launched with Hexa in 2021 that simplifies KYB management and already powers more than 80 clients such as Spendesk, DeFacto, and Payset.
Titouan embodies resilience and technical ingenuity: from a 12-year-old kid drilling a hole in the wall to plug in his Ethernet cable, to a founder capable of pivoting in the face of negative market signals. He looks back on his journey, from teenage hacks to meeting Hexa, and finally to the decisive pivot that turned Dotfile into a reference for onboarding and compliance management.
