Pittsburgh-based Velo AI develops Copilot, an AI-powered cycling safety device that watches behind a rider, warns of approaching vehicles, and records the road. Founded after Clark began exploring safer streets in 2019, the company grew from a smartphone-on-a-bike prototype into hardware small enough for a bike light, with its first Pittsburgh beta riders taking to the streets in 2022. Velo also equips bike-share fleets with sensors that capture near-miss data for cities and transportation planners, including a U.S. Department of Transportation Complete Streets AI Initiative project with POGOH and Carnegie Mellon University.
