Nexos.ai

nexos.ai is a Lithuanian artificial intelligence company based in Vilnius, Lithuania.

The company makes software that manages how organisations use commercial AI models, routing requests between providers and recording usage and costs.

History

nexos.ai was founded in late 2024 by Tomas Okmanas and Eimantas Sabaliauskas, who co-founded Lithuanian technology company Tesonet in 2008 and VPN service NordVPN in 2012.

In January 2025, nexos.ai publicly launched with an $8 million seed round led by Index Ventures.

In October 2025, the company raised a €30 million (approximately $35 million) Series A round co-led by Index Ventures and Evantic Capital. A company spokesperson gave the valuation as €300 million.

As of mid-2026, nexos.ai had raised approximately $43 million in total funding and employed around 120 people.

Disclosed customers include Tesonet portfolio companies and Bulgarian fintech company Payhawk.

Products

nexos.ai's software acts as an intermediary between an organisation's employees and commercial AI providers. Requests pass through the company's systems rather than directly to providers, and can reach around 200 models.

According to the company, the software calculates the cost of each request, records what employees send to AI providers, and detects personally identifiable information (PII), which it can route back to the organisation's own systems.

The software includes an interface for employees alongside a developer-facing component.
