Nexos.ai Secures $35M to Bridge Enterprise AI Security Gap

For most large companies, artificial intelligence remains largely unrealized potential or a critically important security threat. Now, the effort of Lithuania’s most successful entrepreneurial pair to solve this problem is gaining traction – and investment.

Just months after Nexos.ai quietly launched with an $8 million seed round led by Index Ventures, Nord Security co-founders Tomas Okmanas and Eimantas Sabaliauskas have closed a €30 million Series A (roughly $35 million). This new funding fuels their platform designed to help companies safely integrate AI tools by acting as a secure intermediary between employees and AI systems.

Okmanas believes a massive corporate data leak is brewing as employees routinely upload confidential information to Large Language Models (LLMs). Rather of outright banning AI, Nexos.ai aims to be a “Switzerland for LLMs,” offering a neutral space. The platform sits between teams and AI tools, controlling data flow while still allowing companies to benefit from increased productivity.

This potent combination – experienced founders addressing a critical enterprise need – explains the rapid follow-on funding. Index and Evantic Capital co-led the round at a €300 million valuation (approximately $350 million), according to a company spokesperson. Existing investors Creandum and Dig Ventures also participated, alongside angel investors including the CEOs of Datadog, Klarna, Supercell, and Wix.

Evantic, the new venture firm founded by former Sequoia Capital partner Matt Miller, played a key role in closing the round, even as a recent MIT report revealed that 95% of generative AI pilot programs are failing to meet expectations.
