Amsterdam-based startup Wonderful has raised $150 million in a Series B round led by Insight Partners, with participation from existing backers Index Ventures, IVP, Bessemer Venture Partners, and Vine Ventures. The company, which emerged from stealth in mid-2025 with a $34 million seed round, raised a $100 million Series A in November of the same year. It operates in over 30 countries across Europe, the Middle East, Asia-Pacific, and Latin America, serving enterprises in telecoms, financial services, manufacturing, and healthcare. The core product is an enterprise AI agent platform, model-agnostic by design, continuously benchmarking and selecting AI models for each use case. It will use the new capital to grow its headcount from 350 to approximately 900 by year-end.
