Wonderful raises $550 million Series C at a $5 billion valuation

The story so far, in brief; the legwork, and the full article, stay with the original outlet.

Wonderful, founded in 2025 by Bar Winkler and Roey Lalazar, closed a $550 million Series C on 2 September. Insight Partners led it, Salesforce joined, and existing backers Index Ventures, IVP, Vine Ventures, 9Yards and Bessemer Venture Partners came back for more. The round values Wonderful at $5 billion, more than twice the $2 billion it was worth after its Series B in March 2026. That is a fair amount of value to add between March and September.

What it sells is an "AI operating system" for large companies: one shared layer that runs agents, workflows, AI-native applications and integrations, with governance and security on top, so that each department does not end up buying its own agent. It works with any AI model, runs in the cloud or on-premise, and comes with engineers who sit inside the customer until the first use case is live, then hand over. Pricing mixes a platform licence with usage-based fees.

Since March, Wonderful has gone from 30 to more than 35 markets, grown to 650 staff worldwide and now serves about 100 enterprise customers in finance, telecoms, health, manufacturing, utilities and retail. Its Latin American base is Argentina, where a 16-person team covers Argentina, Chile, Uruguay, Paraguay and Bolivia and is expected to reach 30 to 40 people by the end of the year.
