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 its $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.
