The company is headquartered in San Francisco, CA and was founded in 2011 by Sam Street, Sean Plaice, and Bastian Lehmann. Postmates provides merchants the ability to join the platform as partners, which provides them with the benefit of greater exposure through the application, while Postmates benefits from increased order volume.
