Wonderful raises $550 million at $5 billion valuation for AI OS

Wonderful closed a $550 million Series C funding round at a $5 billion valuation, the Israeli-Dutch artificial intelligence startup said Wednesday. The company builds software that coordinates AI agents across enterprises.

Insight Partners led the round, with participation from Salesforce Inc. (NYSE:CRM), Index Ventures, IVP, Vine Ventures, 9Yards, and Bessemer Venture Partners. The funding will accelerate product development and expand Wonderful’s global deployment teams.

Wonderful has expanded to more than 35 markets since its Series B in March 2026. The company now employs 650 people worldwide and has evolved its platform into what it calls an AI operating system. Customers use the platform to automate workflows, build AI applications, and coordinate agents across their organizations.

The Wonderful AI OS serves as a shared operating layer that coordinates agents, workflows, AI-native applications, enterprise context, integrations, and governed execution. The platform is model-agnostic and compatible with existing technology stacks. It includes managed workflows, productivity agents, AI-native applications, and conversational agents.

Wonderful was founded in 2025. Forward-deployed engineers work alongside customers to bring use cases into production and transfer knowledge so enterprises can build and operate the platform independently. The AI OS can be deployed across any cloud environment, including on-premise installations.
