Nebius, the Nasdaq-listed AI cloud company headquartered in Amsterdam, announced on February 10, 2026 that it had agreed to acquire Tavily, an Israeli startup that supplies real-time web search to AI agents. Nebius said it would place Tavily's search tools inside its AI cloud platform next to Token Factory, its inference service.
Neither company disclosed the price. The Israeli business publication Calcalist reported that Nebius would pay $275 million up front and that the total could rise to $400 million if certain milestones were met, according to SiliconANGLE. Nebius said the deal was expected to close within a few weeks, subject to customary conditions.
Tavily's team, including founder and chief executive Rotem Weiss, is joining Nebius and will keep running product development. The Tavily brand will stay in use, and the company will continue to serve its existing customers.
What Tavily built
Tavily sells a developer API that lets AI agents search the web, crawl pages and pull structured data out of them. The aim is to feed current, cleaned-up information into a language model's context window so that an agent's answers are less likely to be outdated or invented. TechCrunch reported that the company also helps businesses keep agents' web access in line with their own policies.
The product grew out of GPT Researcher, an open source project Weiss created in 2023, before ChatGPT could browse the internet. The project collected almost 20,000 stars on GitHub, Weiss told TechCrunch, and he then turned the idea into a company aimed at enterprise customers.
According to Nebius, Tavily records more than 3 million SDK downloads a month and has a developer community of more than one million users. Named customers include IBM, Cohere and Groq, and SiliconANGLE listed MongoDB, Monday.com, LangChain and Amazon Web Services among its users.
“Tavily is on a mission to onboard the next billion AI agents to the web. Agentic search is a multi-billion-dollar opportunity, and we believe the market is poised to grow exponentially as enterprises deploy autonomous AI systems.”
Why Nebius is buying
Nebius emerged from Yandex N.V. in 2023, after the group sold its search engine business but kept its data centres, SiliconANGLE noted. Most of its revenue comes from renting access to Nvidia graphics processors, and it has been adding software on top of that hardware.
The company described the deal as a step toward a single platform on which AI companies and enterprises can build, tune and run autonomous agents. In its framing, Token Factory supplies the inference an agent needs to reason, while Tavily supplies live web access so the agent can check facts. Bringing both under one roof means developers do not have to stitch together services from several vendors, Nebius said.
Roman Chernin, Nebius co-founder and chief business officer, said Tavily was solving a critical part of the stack and had proved it through developer adoption. Nebius cited forecasts that the market for agentic AI could grow from about $7 billion in 2025 to between $140 billion and $200 billion by the early 2030s.
The founders and the funding
Tavily was founded in 2024 by Weiss, Assaf Elovic and Yuval Rozio, according to Insight Partners. Rozio is a managing director at Alpha Wave Global, which incubated the company.
In August 2025 Tavily announced $25 million in total funding, including a $20 million Series A led by Insight Partners and Alpha Wave Global. At the time it said it would use the money to double headcount and expand sales. Insight Partners said the company was headquartered in New York, with offices in Tel Aviv and Abu Dhabi.
Nebius was advised by the Israeli firm Arnon, Tadmor-Levy and by Morgan Lewis, while Tavily used Hogan Lovells and Goldfarb Gross Seligman, Israel Desks reported.
A crowded market for agent search
Tavily competes with Exa, which raised a $17 million Series A in 2024, and with the smaller startup Firecrawl, TechCrunch reported. OpenAI and Perplexity also offer search tools to developers.
Weiss said the company's mission was to bring the next billion AI agents onto the web, and that joining Nebius would help it scale globally. If the Calcalist figures are correct, the initial payment alone was about eleven times the $25 million Tavily had raised in total.
