A London-based developer of agentic AI-native test infrastructure has raised a £14.9 million Series A round led by Redalpine with participation from IQ Capital, Mercia Ventures, UBS and Seedcamp.

The funding for Synthesized will support hiring across North America and Europe in AI R&D, engineering and go-to-market teams.

Founded in 2020 by Nicolai Baldin, the company uses AI to automate the creation of lifelike, regulation-safe test data and environments, helping enterprises accelerate software delivery while staying compliant.

Deutsche Bank, an early customer, has deepened its partnership after seeing test data provisioning times halved.
