European AI breakout Nexos.ai has raised $30 million in Series A funding to help enterprises adopt AI safely — turning what’s often seen as a data risk into a productivity advantage.
The round was co-led by Index Ventures and Evantic Capital, valuing the company at €300 million ($350 million). Previous investors Creandum and Dig Ventures returned, alongside notable angels including the CEOs of Datadog, Klarna, Supercell, and Wix.
Founded by Tomas Okmanas and Eimantas Sabaliauskas — the Lithuanian duo behind Nord Security (maker of NordVPN) — Nexos.ai acts as a secure AI middle layer between employees and large language models (LLMs), ensuring corporate data stays protected while enabling AI use at scale.
“The world’s biggest corporate data leak is happening in slow motion,” said Okmanas, Nexos.ai’s co-founder and CEO. “Employees are pasting sensitive information into public AI tools every day. Banning AI isn’t the answer — we’re building the Switzerland of LLMs, where companies can use any model securely and confidently.”
The “Switzerland for LLMs”
Nexos.ai positions itself as a neutral, governance-first infrastructure for enterprise AI. Its platform includes:
- AI Workspace — a user interface where employees can safely access AI tools.
- AI Gateway — a developer layer providing security, compliance, and cost controls across more than 200 integrated AI models.
The Gateway helps organizations unify fragmented AI usage, manage spend, and control data exposure — key blockers to enterprise adoption. The company plans to use its Series A to accelerate support for private and on-premise AI models, catering to clients handling regulated or sensitive information.
“Every company we talk to wants to use AI — but few can do it responsibly,” said Okmanas. “Our goal is to make AI adoption as safe and structured as cloud migration was a decade ago.”

A Fast Rise Backed by Heavyweights
Nexos.ai’s rise has been unusually fast. The company came out of stealth just months ago with an $8 million seed round led by Index Ventures — and closed its Series A soon after, reportedly without actively fundraising.
“Tomas and Eimantas are two of Europe’s most accomplished operators — this is exactly the kind of team we want to back,” said Matt Miller, former Sequoia Capital partner and founder of Evantic Capital.
Miller’s firm brings with it the Legends Network, a collective of 140 world-class operators who advise Evantic’s portfolio companies in exchange for a share of profits. Okmanas himself is part of that network and says the collaboration is already shaping Nexos.ai’s roadmap.
From NordVPN to Nexos.ai
Before Nexos.ai, Okmanas and Sabaliauskas bootstrapped Nord Security into a $3 billion cybersecurity powerhouse — giving them a front-row view of how companies struggle with data governance.
They spotted the opportunity for Nexos.ai while managing Tesonet, their venture builder and investment group. Within Tesonet’s portfolio, AI tools had already cut costs dramatically — at Hostinger, AI reduced customer support hiring needs by 500 people, saving the company €10 million in 2024 alone.
Seeing that potential, the founders decided to build the infrastructure layer enabling AI adoption across regulated sectors, public institutions, and enterprise IT systems.
Expansion and Market Outlook
Nexos.ai is currently running 50–60 product demos per week with major European and North American enterprises. Its early customers include Payhawk (Bulgaria’s first fintech unicorn) and several Tesonet portfolio companies.
The company plans to grow its team to 100 employees by early 2026, expanding its presence across Europe and North America.
“AI adoption will only scale when trust does,” said Okmanas. “Nexos is here to build that trust layer — so enterprises can move fast without breaking security.”
