Nord Security and the Tesonet venture-builder family
Nord Security sits inside the Lithuanian venture builder Tesonet, co-founded in 2008 by childhood friends Tomas Okmanas and Eimantas Sabaliauskas. After dozens of early product experiments, NordVPN — often described as their 35th venture — became the breakthrough that scaled into Nord Security. Tesonet founds, accelerates and co-invests across cybersecurity, web data, AI, hosting and sportstech, with 4,200+ people across the wider ecosystem.
Sister and related companies commonly linked with Nord Security include Surfshark (merged with Nord Security in 2022 into a joint cybersecurity group), Oxylabs / Decodo and other Source.ai web-data businesses, Hostinger, nexos.ai (Index Ventures–backed enterprise AI workspace from the same founders), CyberCare, Mediatech, CAST AI, Lovable, Wonderful, Eneba and Turing College, among others in Tesonet’s portfolio.
Scale (public reports): Verslo žinios reported that the combined Nord Security and Surfshark group crossed €1 billion in 2025 revenue (up ~40% year on year; separate company splits not disclosed). Oxylabs has publicly been linked to roughly $350 million ARR and a ~$3.6 billion valuation after its 2026 Warburg Pincus growth round. Hostinger reported €275.4 million revenue for 2025.
Cyber City campus: Tesonet’s Vilnius hub Cyber City (Švitrigailos St.) comprises four Class A+ buildings on the former Sparta factory site, with 3,300+ people on campus. It sits across from Vinted’s offices; Vilnius renamed nearby public-transport stops “Unicorn” (Vienaragių) to mark the local unicorn cluster.
Sports: Tesonet owns the London Lions basketball club and has publicly advanced plans for a purpose-built multi-use arena in London (feasibility work and city backing reported in 2025).
