Wonderful more than doubles its valuation to $5B in under 6 months

Israeli-Dutch AI startup Wonderful has raised $550 million in a Series C funding round that gives it a price tag of $5 billion, more than doubling the $2 billion valuation the company gained when it last raised funding nearly six months ago.

Insight Partners returned to lead this round, too, and existing investors Index Ventures, IVP, Vine Ventures, 9Yards, and Bessemer Venture Partners are participating once again. Salesforce is investing in the company for the first time in this round.

Founded in early 2025, Wonderful has grown blazingly fast. It initially saw strong traction with its customer service AI agent platform, which it built and customized to sell in various non-English-speaking markets. Its strategy of deploying engineering teams to work with its customers, sometimes on their premises, to deploy and integrate its AI tech into their workflows and systems also proved very successful. The company says it now works across more than 35 countries.

The startup’s core offering has evolved over the past few months, though. Departing from its customer service roots, Wonderful now offers a platform, dubbed “Wonderful AI OS,” which it says can coordinate and connect agents, workflows, and AI applications with companies’ data, context, and existing integrations. The company says the platform works with any AI model and is compatible with existing tech stacks.

“Customers can adopt whichever parts of the platform make the most sense, integrate them with existing systems, choose the best models for each workload, and retain ownership of everything they build,” Roey Lalazar, Wonderful CTO and co-founder, said in a statement.

The company is still leaning on its forward-deployed engineers to help embed its products quickly into companies — which appears to be a good strategy given the demand for experts versed in implementing AI services and products.

Wonderful said it will use the fresh $550 million to develop products faster, expand its FDE teams, and meet demand for its products.
