nexos.ai, a brand of Tesonet, has raised €30 million in Series A funding to securely accelerate enterprise AI adoption.

The round was co-led by Evantic Capital, the debut fund of former Sequoia Capital partner Matt Miller, and Index Ventures, with participation from existing investors Creandum, Dig Ventures, and notable angel investors.

As part of the Tesonet ecosystem, nexos.ai leverages over a decade of experience building secure, scalable technology infrastructure to tackle one of today’s biggest enterprise challenges: safe and efficient AI adoption. The funding will expand the platform’s capabilities across security, observability, governance, and cost management—helping organizations deploy and manage AI tools without exposing sensitive data or losing visibility.

The raise comes just six months after the platform’s public launch in January 2025, amid growing reports of an uncontrolled “Shadow AI” phenomenon—employees at major corporations using consumer AI tools for sensitive tasks, inadvertently leaking proprietary data to third parties.

“While security teams focus on traditional cyber threats like ransomware, their own employees are carrying out the biggest data leak in corporate history right under their noses,” said Tomas Okmanas, CEO and co-founder of nexos.ai and Tesonet.

Co-founders Tomas and Eimantas, identified the governance gap behind Shadow AI while advising Tesonet’s portfolio companies. According to Okmanas, enterprise AI adoption faces four major obstacles: fragmented and insecure deployments, uncontrolled costs, zero visibility, and failed governance.

“Companies follow the same journey: initial AI excitement, then chaos—tools don’t integrate, costs spiral, and most projects are abandoned. Enterprises have 12–24 months to architect proper AI infrastructure or risk falling behind competitively,” Okmanas added.

nexos.ai’s platform combines a secure AI Workspace for employees with an AI Gateway for developers—creating a unified control layer for over 200 AI models. This allows organizations to route workloads to the best-performing model while maintaining centralized control over data, costs, and compliance.

• The AI Workspace provides a secure, web-based interface where teams can chat with multiple LLMs, compare models, collaborate on AI projects, and maintain compliance through guardrails, access controls, and detailed activity logging.

• The AI Gateway offers developers plug-and-play API orchestration, intelligent caching for cost optimization, RAG (Retrieval-Augmented Generation) for grounding in company data, and private model hosting for sensitive workloads.

“Tomas Okmanas is a force of nature in European tech,” said Matt Miller, founder of Evantic Capital. “With Tesonet’s proven track record in cybersecurity and infrastructure, nexos.ai is uniquely positioned to provide enterprises the governance and compliance layer they need to deploy AI safely and at scale.”

Hannah Seal, Partner at Index Ventures, added: “nexos.ai has rapidly evolved from concept to enterprise-ready platform, driven by urgent demand for secure AI deployment. Backed by Tesonet’s deep technical foundation and global experience, the team is exceptionally well placed to help enterprises achieve measurable ROI from AI.”

The new funding will fuel platform development — including advanced routing algorithms, private model deployment, and expansion across Europe and North America — while also supporting educational partnerships to close the enterprise AI skills gap.
