Wonderful Raises $550M, More Than Doubles Valuation to $5B
Wonderful raises $550 million at a $5 billion valuation, more than twice its level six months ago, to expand AI OS and engineering teams across global markets.
Summary
Israeli-Dutch AI startup Wonderful announced a $550 million Series C on September 2, 2026, valuing it at $5 billion, more than double its $2 billion valuation nearly six months earlier. Insight Partners returned as lead investor, joined again by Index Ventures, IVP, Vine Ventures, 9Yards and Bessemer Venture Partners. Salesforce invested for the first time.
Founded in early 2025, Wonderful says it operates across more than 35 countries after gaining traction by tailoring customer service AI agents for non-English-speaking markets and deploying engineers, sometimes on customer premises, to integrate them. Its newer Wonderful AI OS connects agents, workflows and AI applications with company data, context and existing integrations. Wonderful says it supports any AI model and existing technology stack. CTO and co-founder Roey Lalazar said customers can adopt selected components, choose models, integrate existing systems and retain ownership of their work. Wonderful will use the funding to accelerate product development, expand its forward-deployed engineering teams and meet demand.

Risks & concerns
