Wonderful raised $550 million in a Series C round at a $5 billion valuation. That is more than double the $2 billion it was worth six months earlier. Insight Partners led again. Index Ventures, IVP, Vine Ventures, 9Yards and Bessemer took part once more. Salesforce invested for the first time. The Israeli-Dutch company started in early 2025 with a customer service agent platform for non-English markets. It now sells Wonderful AI OS, which links agents, workflows and AI applications to a company's own data and systems. Wonderful says the platform works with any AI model and existing tech stacks. It says it operates in more than 35 countries. The money will fund faster product work and larger forward-deployed engineering teams.
