Tesonet

Tesonet is a prominent technology hub and global business accelerator based in Vilnius, Lithuania. Founded in 2008 by Eimantas Sabaliauskas and Tomas Okmanas, the company has evolved from a small startup into a powerhouse in the cybersecurity and software development sectors. It is best known for being the incubator and original developer of Nord Security (the company behind NordVPN) and Surfshark.

Today, Tesonet operates as a diverse ecosystem, providing infrastructure, investment, and strategic guidance to more than 30 global products.
