Oxylabs has raised $130M from private equity firm Warburg Pincus. It is the company’s first outside investment since it launched in 2015. The deal values the Vilnius-based data infrastructure firm at around $3.6bn. Oxylabs announced the raise on Thursday.

The figure is striking for a firm that bootstrapped its way to the top. Oxylabs says it now runs at $350m in annual recurring revenue. It counts more than 350,000 customers. That makes it the second unicorn to spin out of the Tesonet accelerator, after NordVPN maker Nord Security. It is also one of the most valuable companies in Lithuania’s history.

Selling shovels for the agentic web

Oxylabs sells the plumbing for gathering public web data at scale. It began as a premium proxy service. That kind of tool routes a company’s requests through many addresses, so it can collect prices, listings, or threat data without getting blocked. Today it pitches itself as a full web-data platform. It holds more than 160 patents and handles billions of requests a day.

The timing is the pitch. AI agents are starting to browse the web far more than humans do. They need a live feed of what is out there, not a stale index. “The next generation of AI won’t be powered by static indexes,” said chief executive Vytautas Savickas. That, he argues, is the market Oxylabs has spent a decade building for.
