dRISK

Founded in 2014 by CEO Chess Stetson and operating from Pasadena, California and London, dRISK builds a platform for finding, generating, and training autonomous vehicles on the high-risk edge cases — the rare 'unknown unknowns' — that account for a disproportionate share of crashes. Its technology uses knowledge-graph-style networks of real-world incident and scenario data to store, visualize, and classify these edge cases in a form AV training and testing systems can absorb, and the company has reported measurable improvements in retraining AVs to detect high-risk situations. dRISK raised a £1.7M super-seed round led by Foresight Williams Technology in 2022 and has participated in UK government-funded autonomous-vehicle safety consortia.
