Synthesized is a London- and New York-based company applying artificial intelligence to one of software development's most persistent bottlenecks: testing and the test data that powers it. As demand for quality assurance surges across the tech industry — accelerated by the explosion of AI-generated code — Synthesized positions itself as a verification layer for building and shipping software in the AI era.
The company's origins lie in machine learning. Founder Nicolai Baldin started Synthesized in 2020 after completing a PhD in machine learning and statistics at the University of Cambridge, initially focusing on automated testing of ML algorithms to surface the edge cases where models fail. The company also built tools for assessing bias in machine-learning models. Over time, Synthesized expanded into testing traditional rule-based software as well, broadening its relevance to mainstream enterprise engineering.
A central pillar of the platform is intelligent test-data generation. High-quality, representative, and privacy-compliant test data is notoriously hard to assemble, and Synthesized automates it. The impact is measurable: Deutsche Bank, both an investor and a customer, reports that Synthesized cut in half the time required to find test data for its software evaluations, while other customers have seen QA costs reduced by 40%.
The enterprise validation is significant in regulated industries where test data must be both realistic and compliant. By generating safe, useful data and automating the testing built on top of it, Synthesized helps large organizations move faster without sacrificing rigor — a balance that matters more as AI pushes more code into production.
Synthesized raised $20 million in a Series A led by Redalpine Venture Partners, with participation from IQ Capital, Mercia Ventures, UBS, Seedcamp, and returning investor Deutsche Bank. The roughly 35-person company plans to double its team and expand across North America and Europe, scaling its AI-driven testing and test-data platform for the enterprise market.
