Wonderful more than doubles its valuation to $5B in under 6 months

Israeli-Dutch AI startup Wonderful has raised $550 million in a Series C funding round that gives it a price tag of $5 billion, more than doubling the $2 billion valuation it gained nearly six months ago. Insight Partners led the round, with participation from existing investors including Index Ventures, IVP, Vine Ventures, 9Yards, and Bessemer Venture Partners, alongside new investor Salesforce. Founded in early 2025, Wonderful grew rapidly with its customer service AI agent platform and its strategy of deploying engineering teams directly with customers to integrate AI tech into their workflows. The startup’s core offering has recently evolved into a platform dubbed “Wonderful AI OS,” designed to coordinate and connect agents, workflows, and AI applications with companies’ existing data and integrations. Wonderful CTO and co-founder Roey Lalazar noted that customers can adopt whichever parts of the platform suit their systems while retaining ownership of their builds. The company announced it will use the fresh $550 million to develop products faster, expand its forward-deployed engineering teams, and meet international demand across more than 35 countries.
