European AI Startup Nexos.ai Secures €30M Series A to Bridge - Enterprise AI Security Platform Attracts Major Funding Europea

Enterprise AI Security Platform Attracts Major Funding

European AI startup Nexos.ai has reportedly secured €30 million (approximately $35 million) in Series A funding just months after emerging from stealth mode, according to recent reports. The Lithuania-based company, founded by Nord Security co-founders Tomas Okmanas and Eimantas Sabaliauskas, aims to solve what sources describe as the “biggest corporate data leak” in progress as employees increasingly upload sensitive information to large language models.

The “Switzerland for LLMs” Approach

Rather than banning AI tools outright, Nexos.ai positions itself as what Okmanas calls a “Switzerland for LLMs,” serving as a neutral intermediary between enterprise teams and AI systems. The platform reportedly maintains data control while preserving the productivity benefits that companies seek but often hesitate to pursue due to security concerns. Analysts suggest this approach addresses a critical gap in enterprise AI adoption, where security fears have prevented many organizations from fully leveraging AI capabilities.

Seasoned Founders Drive Rapid Funding Round

The substantial Series A round was reportedly co-led by Index Ventures and Evantic Capital at a €300 million valuation (approximately $350 million), according to company statements. Previous investors Creandum and Dig Ventures also participated, alongside angel backers including the CEOs of Datadog, Klarna, Supercell, and Wix. Sources indicate that Evantic, the new venture firm launched by former Sequoia Capital partner Matt Miller, was particularly persistent in making the investment happen even though Nexos.ai wasn’t actively fundraising.

The report states that the founders, who famously bootstrapped their previous cybersecurity company Nord (the company behind NordVPN) to a $3 billion valuation, now recognize the value-add from venture capital partners. In addition to financial backing, Nexos.ai is reportedly benefiting from Miller’s ‘Legends’ network—140 operators who advise Evantic’s portfolio startups in exchange for a share of the fund’s profits.

Platform Architecture and Expansion Plans

Nexos.ai’s current product consists of two main components: an AI Workspace interface for employees and an AI Gateway for developers. The gateway reportedly functions as a control layer for security, cost management, and compliance oversight while reducing what Okmanas identifies as a key barrier to AI adoption—fragmentation. The platform provides single access to approximately 200 AI models, and the company plans to use the new funding to accelerate support for private models handling sensitive data.

According to the coverage, the startup is currently conducting 50 to 60 demo calls weekly but anticipates that traditional businesses will need significant internal work to convince their boards about AI adoption strategies. The funding will reportedly support expansion across Europe and North America, with the team expected to grow to 100 people by the company’s first anniversary.

Addressing Regulatory and Sovereignty Concerns

Nexos.ai is initially focusing on two key customer segments: tech-savvy companies already using AI daily, and organizations in regulated industries concerned about governance and data sovereignty. The report indicates that European data sovereignty concerns have begun opening doors for Nexos.ai at public institutions, potentially creating a new market beyond its enterprise focus.

The founders identified the AI governance gap while overseeing the portfolio of Tesonet, their company that builds and invests in startups. Tesonet portfolio companies are among Nexos.ai’s disclosed customers, alongside Bulgarian fintech unicorn Payhawk, which maintains an office in Vilnius.

Demonstrating Tangible AI Value

While boards continue debating whether AI can deliver real value, Okmanas points to results within Tesonet’s own portfolio as evidence. At Hostinger, a web hosting provider, an AI assistant reportedly reduced the need for human support significantly. “That’s why we didn’t need to hire 500 people and saved €10 million this year alone,” Okmanas stated, according to the report.

Despite discussing specific numbers from portfolio companies, the founders declined to disclose Nexos.ai’s own revenue figures. Instead, they emphasized their mission to remove barriers to broader AI adoption while maintaining the security and governance requirements that enterprises demand.
