nexos.ai, an all-in-one AI platform out of Lithuania, has closed a €30 million Series A to scale its platform’s abilities to remove blockers to enterprise AI adoption like security, observability, governance and cost control, allowing companies to more quickly benefit from the use of AI models in their business.
The funding round was co-led by former Sequoia Capital partner Matt Miller’s debut fund Evantic Capital and existing investor Index Ventures. Previous investors Creandum, Dig Ventures, and notable angels also participated.
“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 nexos.ai CEO and Co-founder Tomas Okmanas.
Across the region, startups such as the UK-based Synthesized (€17 million Series A for AI-driven test-data management), Denmark’s Light (€25 million Series A for AI-native financial platforms), Sweden’s EvoluteIQ (€44 million growth round for agentic-AI process automation), and the UK’s Conduct (€11.2 million Seed round for modernising enterprise IT systems) have each attracted investor attention.
While none are Lithuanian, Sweden’s EvoluteIQ stands out as a Nordic neighbour pursuing similar enterprise-AI goals.
Together, these fundings illustrate growing investor confidence in platforms that underpin secure, compliant, and scalable AI adoption across large organisations – an ecosystem into which nexos.ai fits squarely.
Matt Miller, whose new fund Evantic Capital led the round, said: “Tomas Okmanas is a force of nature in the European tech scene having built several successful companies including Nord Security. It is a thrill for us to partner with him and his team on their latest endeavor to provide compliance and secure access to AI services to the enterprise and mid-market.”
EU-Startups reported on Evantic Capital’s debut back in September, in which nexos.ai was identified in the fund’s early investments as part of its B2B-AI portfolio.
Miller, who previously helped scale Confluent and dbt Labs at Sequoia Capital, added: “nexos.ai addresses the fundamental infrastructure gap preventing enterprises from capturing AI’s value while maintaining security control.”
Founded in 2024 by the creators of cybersecurity unicorn Nord Security, Nexos.ai is an all-in-one AI platform to drive secure, organisation-wide AI adoption. Okmanas, who, together with Co-founder Eimantas Sabaliauskas bootstrapped Nord Security to global market leadership over 12 years, identified the governance gap developing into a pattern while overseeing their own portfolio companies at Tesonet.
EU-Startups profiled Nord Security in a 2022 article, “Nord Security raises first-ever outside capital and becomes Lithuania’s latest unicorn”, which detailed its €91.6 million funding round that pushed its valuation beyond €1.4 billion.
Okmanas believes enterprise AI adoption faces four critical barriers: fragmented and insecure deployments, uncontrolled costs, zero visibility, and failed governance blocking scaling.
Through a secure, web-based AI Workspace for employees and an AI Gateway for developers, nexos.ai enables companies to replace scattered AI tools with a unified interface that provides built-in guardrails, full visibility, and flexible access controls across all leading AI models – allowing teams to move fast while maintaining security and compliance.
The round, which was closed just six months after nexos.ai’s launch in January, comes as enterprises report an uncontrolled ‘Shadow AI’ challenge. Employees at major corporations routinely upload confidential financial data, legal documents, and strategic plans to consumer AI tools, inadvertently feeding sensitive information into third-party training datasets accessible to competitors.
“Companies follow the same journey: initial AI excitement, then they buy everything, nothing works together, costs explode, and they end up throwing most of it away. Enterprises have between 12-24 months to architect proper AI infrastructure or face existential competitive disadvantage,” Okmanas said.
nexos.ai’s platform combines an AI Workspace interface for employees with an AI Gateway for developers, providing a unified control layer for over 200 AI models, enabling enterprises to route tasks to optimal models while maintaining centralised security, cost management, and compliance oversight.
The AI Workspace enables teams to chat with multiple LLMs in one interface while maintaining security through customisable guardrails and role-based access controls. Teams can compare models side-by-side, work with any file format, and collaborate on AI projects with built-in web search capabilities – all while reportedly preventing data leaks through detailed logging and trace visibility.
The AI Gateway provides developers with plug-and-play API access to orchestrate all models through one endpoint, intelligent caching to reduce costs and improve latency, and Retrieval-Augmented Generation (RAG) capabilities to ground responses in company documents.
Smart fallbacks and load balancing ensure uninterrupted workflows even during model outages, while private model hosting options serve teams working with sensitive data.
Hannah Seal, Partner at Index Ventures, said: “nexos.ai has rapidly evolved from concept to enterprise-ready platform, driven by urgent market demand to deploy AI securely and remove barriers to adoption. As enterprises move from running pilot projects to full-scale deployment, many are turning to nexos.ai to help them deliver clear ROI – and with a team experienced in building best-in-class software, the company is exceptionally well positioned to capture this demand.”
The funding will accelerate platform development, including advanced routing algorithms, private model deployment capabilities, and expansion across Europe and North America, helping nexos.ai partner with more enterprises to overcome the barriers they face when integrating AI tools.
The company also plans to launch educational partnerships to address enterprise AI skills gaps.
