About Us We’re a team of builders and operators who love solving tough problems. Our founders - Vincent (ex-SoundCloud), Caterina (ex-Uber), and Bella (ex-HubSpot) - met while scaling operations at Dance and saw firsthand how critical supply chain and procurement operations are to real-world products. So we built Dexter to help. We’re backed by Y Combinator and growing fast.
