AI startup Wonderful hits $5 billion valuation after raising $550 million in six months
The Israeli-Dutch company more than doubled its value since its last funding round. Its secret weapon: teams of engineers who move into clients' offices and wire up AI tools by hand.
Key points
- Wonderful raised $550 million in a Series C round in 2025, valuing the company at $5 billion.
- That valuation is more than double the $2 billion figure Wonderful carried less than six months ago.
- Insight Partners led both rounds; Salesforce joined as a new investor.
- Founded in early 2025, Wonderful now operates across more than 35 countries.
- The company plans to use the new funds to build products faster and expand its on-site engineering teams.
Wonderful, a startup founded in early 2025 with offices in Israel and the Netherlands, has raised $550 million in a Series C round, the type of large, later-stage funding that comes after a company has proved it can grow. The deal values the company at $5 billion, up from $2 billion when it last raised money less than six months ago.
Investment firm Insight Partners led this round, just as it did the previous one. Returning backers Index Ventures, IVP, Vine Ventures, 9Yards and Bessemer Venture Partners joined in again. Salesforce, the business-software giant, invested for the first time.
What does Wonderful actually do?
Wonderful sells software that coordinates AI agents, which are programs that carry out multi-step tasks on their own, across a company's existing tools and data. It calls the platform "Wonderful AI OS." The company says it works with any AI model and slots into whatever software a business already uses.
The platform started life as a customer service tool, built for companies that operate outside English-speaking markets. That focus on non-English speakers gave Wonderful an early edge in regions that bigger US rivals often overlook.
Its other edge is people. Wonderful sends its own engineers, called forward-deployed engineers, directly to client sites to install and connect its software by hand. That approach is slower and more expensive than selling software online, but it works. Clients get a working system; Wonderful gets deep knowledge of how real businesses actually run.
CTO and co-founder Roey Lalazar put it plainly: "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."
What happens next?
The $550 million goes toward faster product development and more on-site engineering teams to meet demand. Wonderful already works in more than 35 countries, a figure that itself is less than a year old.
The raise was first reported by TechCrunch AI.
For businesses thinking about AI tools, Wonderful's model is worth watching: a company that grows by doing the messy integration work that most software vendors leave to the customer. Whether that model stays profitable at $5 billion is the question investors are now betting on.
