Nexos AI, the Lithuanian AI orchestration startup founded by Nord Security veterans, has closed a €30 million Series A round at a €300 million valuation.
Index Ventures and Evantic Capital co-led the investment, with participation from Creandum, Dig Ventures, and angel investors including CEOs from Datadog, Klarna, Supercell, and Wix.
The funding comes just nine months after the company emerged from stealth with an $8 million seed round, signaling extraordinary investor confidence in the enterprise AI security space.
Why Enterprise AI Needs a Neutral Intermediary?
Corporate employees are creating what co-founder Tomas Okmanas calls “the biggest data leak” by uploading sensitive information to public AI models like ChatGPT.
Companies face an impossible choice: ban AI tools and lose productivity, or allow unrestricted access and risk data breaches.
Nexos AI solves this by positioning itself as a secure middleware platform between employees and 200+ AI models from OpenAI, Google, Meta, and others.
The platform provides smart routing, cost optimization, and enterprise-grade security controls without sacrificing the productivity gains businesses desperately need.
The Founders Behind the Vision
Tomas Okmanas and Eimantas Sabaliauskas previously bootstrapped Nord Security to a $3 billion valuation before raising their first institutional capital.
Their track record of building global cybersecurity brands made this one of 2025's fastest enterprise AI fundraises.
Founded in 2024 and headquartered in Vilnius, Nexos AI represents Index Ventures' first-ever investment in Lithuania.
The founders' expertise in security infrastructure positions them uniquely to tackle enterprise AI's most critical challenge: maintaining data control while enabling AI adoption.
