Wonderful Raises $550 Million Series C to Scale the AI Operating System for the Enterprise

Wonderful, the AI OS for the enterprise, announced the closing of a $550 million Series C funding round at a $5 billion valuation. The round was led by Insight Partners, with participation from Salesforce and existing investors Index Ventures, IVP, Vine Ventures, 9Yards, and Bessemer Venture Partners.

Since its Series B in March 2026, Wonderful has expanded its operations to more than 35 markets, grown to 650 employees worldwide, and evolved its platform into a full AI operating system. Customers are now using the Wonderful AI OS to automate end-to-end workflows, build and deploy AI-native applications, and coordinate agents across every part of the enterprise.

"We're entering a new era of enterprise transformation," said Bar Winkler, CEO and co-founder of Wonderful. "Just as cloud platforms became the foundation of the modern enterprise, AI operating systems will become the foundation of every enterprise. Organizations need a shared AI foundation that compounds in value as more of the enterprise relies on it, and that's exactly what we're building."

The Wonderful AI OS is the shared operating layer that coordinates agents, workflows, AI-native applications, enterprise context, integrations, and governed execution across the organization. It's open, model-agnostic and compatible with existing technology stacks, allowing enterprises to adopt new models and capabilities as the industry evolves, without becoming dependent on a single provider.

"The agent is only as strong as the harness around it," said Roey Lalazar, CTO and Co-founder of Wonderful. Products in the AI OS, including managed workflows, productivity agents, AI-native applications, coding agents, and conversational agents, can be deployed independently or combined within the same workflow, with shared governance, security, and orchestration across the platform.

"This region has often been last in line for new enterprise technologies. Not this time. Enterprises across the Adriatic, Hungary and the Baltics are putting AI into production in weeks, not quarters. This round means we can bring that to every major company from Zagreb to Vilnius." said Vedran Bajer, General Manager for Adriatic, Hungary and Baltics at Wonderful.

Wonderful's forward-deployed engineers work alongside customers to bring their first use case into production, then transfer knowledge and capability so enterprises can increasingly build, expand, and operate the platform independently. The AI OS can be deployed across any cloud environment, including on-premise, giving organizations maximum flexibility to adopt AI within their existing security and governance requirements.
