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

Wonderful, building applied AI for the enterprise, led by Bar Winkler, Roey Lalazar, and the team, has announced the closing of a $550 million Series C funding round at a $5B 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 to 35+ markets, grown to 650 employees, and evolved its platform into a full AI operating system. The new funding will accelerate product development, global deployment, and enterprise adoption.

“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. Our customers are already proving that once AI reaches production in one part of the business, it quickly expands across the enterprise. Without a shared operating system, AI risks recreating the sprawl of traditional SaaS. 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. This funding allows us to help more enterprises make that transition.”

The Wonderful AI OS provides a shared operating layer for coordinating agents, workflows, AI-native applications, enterprise context, integrations, and governed execution. It is model-agnostic and compatible with existing technology stacks, allowing enterprises to adopt new models without rebuilding infrastructure or becoming locked into a single provider.

The platform includes managed workflows, productivity agents, AI-native applications, and conversational agents. These products can operate independently or together, with shared governance, security, and orchestration.

“We designed the AI OS to be modular and open because enterprises shouldn’t have to replace everything they already have to become AI-native,” said Roey Lalazar, CTO and Co-founder of Wonderful. “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. That openness preserves our customers’ optionality, while keeping us accountable to stay at the frontier.”

Wonderful’s forward-deployed engineers work with customers to take initial use cases into production, then transfer the expertise needed for increasingly independent deployment and operation. The AI OS supports any cloud environment, including on-premises deployments, enabling adoption within existing security and governance requirements.

“Wonderful is pursuing one of the largest opportunities in enterprise AI,” said Jeff Horing, Co-founder and Managing Director of Insight Partners. “While many companies apply AI to individual departments or use cases, Wonderful is building an operating layer for scaling AI across entire organizations. The team has demonstrated this vision through deployments across dozens of markets and successful production rollouts at major enterprises.”
