History

Having originally met in an IRC channel in 1999, Tomas Okmanas and Eimantas Sabaliauskas founded Tesonet in 2008 for a single project. In the end, however, it took 34 different projects and ideas – from web hosting and e-commerce to video games – to hit upon a viable business model.

NordVPN, the company’s first successful global product, was established in 2012, with a native Windows app coming out in September 2013.

In 2020, Verslo Žinios – the leading business media outlet in Lithuania – gave Okmanas the CEO of the Year award for his achievements as head of Nord Security, one of Tesonet’s largest companies.

In 2021, Tesonet’s customer service department, CyberCare, became a separate company, while remaining a part of the accelerator’s ecosystem. The move was made to ensure better support for Tesonet’s growing number of customers around the world. CyberCare provides multi-lingual services to people from 170 countries and resolves over 11 million enquiries per year. As of 2025, its team consists of more than 400 employees.

In 2022, after raising $100mln. from investors, Nord Security became Lithuania’s second unicorn, with a valuation of 1.6 billion US dollars. Speaking with CNBC News, Okmanas said it was the first time the company has taken external funding. Tesonet also partnered with BC Kauno Žalgiris and launched the sports and tech startup Žalgiris Ventures intended to promote innovation and expand the club’s range of fan services.

In 2024, the company also tripled its investment in the biotechnology startup MISHKAY Biotech and acquired the professional basketball team London Lions based in Stratford, East London.

Local & global presence

In 2023, Okmanas took 965th place in Crunchbase’s global startup founder rankings and took part in the World Economic Forum at Davos.

In 2024, both co-founders, Okmanas and Sabaliauskas, were named National Patrons by the Lithuanian Government for donating over 1 million euros to the public enterprise Mėlyna ir Geltona, founded as a means of providing support to Ukraine. The Lithuanian Reputation Index also found Tesonet to be the second most-reputable company in the country.

In 2022, CyberCare opened an office in Lviv, Ukraine. Although planning for the move started before the war, according to Dainius Vanagas, CEO of CyberCare, one of the reasons why it was followed through was a desire to help Ukraine rebuild.
