Delivery from all your favorites places on-demand


At Postmates X, we are reimagining how things move in cities. Serve, our personable sidewalk delivery robot, is our vision for the future of delivery. It’s designed to take deliveries away from congested streets and onto underutilized alleys and sidewalks, to save energy, reduce emissions, reduce traffic, and make deliveries faster and cheaper. Why move two-pound burritos with two-ton cars? 

Serve has been years in the making and has already done thousands of customer deliveries.
