Wonderful raises $550M at $5B valuation to build AI operating system for enterprises

Wonderful has pulled in $550 million at a $5 billion valuation, more than doubling the price tag it hit only six months ago. For a company that didn’t exist two years ago, that is a very fast rise, even by startup standards.

The round was led by Insight Partners for the third time in a row. Salesforce joined as a new investor, alongside Index Ventures, IVP, Vine Ventures, 9Yards and Bessemer Venture Partners. The new money lifts Wonderful’s total funding to more than $800 million in less than two years.

Founded in early 2025 by Bar Winkler and Roey Lalazar in Tel Aviv, Wonderful is now based in Amsterdam. Winkler previously founded Approve.com, later acquired by Tipalti, and was also an early employee at ironSource. Lalazar had already built Kaps, an AI localisation platform, before becoming Wonderful’s CTO.

The company started with a customer-service agent for non-English-speaking markets, but the pitch has expanded. Wonderful now talks about an “AI operating system” for enterprises: a model-agnostic platform that brings together AI agents, internal workflows and company context without ripping out existing software. A bank, in its telling, could run customer support and compliance on the same layer, with shared governance, while Wonderful’s engineers help set things up inside the customer’s organisation before handing it over.

That broader pitch is what makes the round interesting. Plenty of startups are trying to own one slice of the enterprise AI stack. Wonderful wants the whole stack: agents, workflows, applications and governance. It has also expanded into more than 35 markets and grown from 350 employees at the time of its Series B to about 650 now, with roughly half of them in Israel. The fresh capital is meant to push product development and global deployment teams, while Insight says it plans to help triple the size of Wonderful’s Israel-based development centre over the next year.

And there’s a reason investors are circling the plumbing rather than the shiny front-end agent. The global AI agents market is projected to grow from roughly $8 billion in 2025 to more than $52 billion by 2030. That’s the kind of number that makes everyone pretend they’re buying infrastructure, not hype.
