London-based Synthesized has secured a £14.9 million Series A funding round to accelerate adoption of its AI-native test infrastructure platform across North America and Europe.
The round was led by Redalpine, with participation from IQ Capital, Mercia Ventures, UBS and Seedcamp.
Existing backer Deutsche Bank has also deepened its strategic relationship with the startup after deploying the platform internally.
With this fresh funding, the company also plans to ramp up hiring across go-to-market, customer success, AI R&D and engineering.
Founded in 2020 by Nicolai Baldin, Synthesized uses agentic AI to automate creating lifelike, regulation-safe test data and environments in minutes instead of weeks.
The business says its platform halves compliance workloads, cuts cloud migration timelines by up to 75% and allows enterprises to release software twice as fast.
Clients have reported a 50% reduction in test data provisioning times, while other global firms have seen quality assurance spending drop by up to 40%.
“Test data infrastructure is the foundation for quality software,” said Nicolai Baldin, founder and CEO of Synthesized.
“By embedding agentic AI into every layer of testing, we’re enabling organizations to modernize QA processes, accelerate digital transformation and confidently adopt AI-native testing.”
Daniel Graf, general partner at Redalpine, added: “Synthesized is tackling one of the most urgent and overlooked challenges in the age of AI: how to test, validate, and trust what we build.
“Their platform doesn’t just generate high-quality test data – it lays the foundation for a new class of autonomous QA agents that will transform how modern software is verified and shipped.”
