Commercial contractors are critical to maintaining a building’s key infrastructure, such as elevators, escalators, security systems, and more. However, their business potential is limited by their antiquated, manual go-to-market strategies. Charlie Warren, Blake Meulmester and Brandon Dement saw the need for software in the commercial services business, creating Convex as a result. Convex is an enterprise software company focusing on helping commercial servicers increase their revenues through data-driven go-to-market strategies and improved customer discovery techniques. The San Francisco-based startup participated in Y Combinator’s Winter 2019 batch.
