Postmates enables anyone to have just about anything on-demand. We pioneered the on-demand space & currently serve 3500+ cities with a fleet of more than 350,000 Postmates & the largest network of merchants in the US.

Postmates isnt just an app, its a way of life & a part of pop culture. We are the O.G. of on-demand & weve given people a new superpower the ability to Postmate anything from anywhere.
