Our story

Our story started when Istvan Lam, at the age of 12, received his first cryptography book as a gift from his family. It sparked his interest in cybersecurity and led him to start his fight for digital privacy in his late teens and research cryptography further.

Ten years later in 2011, he founded Tresorit with Szilveszter Szebeni and Gyorgy Szilagyi - both fellow students at EPFL, one of Europes most prestigious tech universities based in Lausanne. Since then, Tresorit has grown into a company bringing secure collaboration to teams all over the world.
