RIVR is turning doorstep delivery into Amazon's wheeled-legged robot bet

Amazon acquired RIVR on March 19, 2026, less than a year after the Zurich company launched U.S. doorstep delivery work with Veho in Austin. TechCrunch reported the acquisition after RIVR had already shown robots in action with Veho and announced European doorstep work with Just Eat Takeaway.com in Milton Keynes.

The Austin launch explains the commercial hook. RIVR and Veho framed the problem as the last 100 yards between vehicle and doorstep, where stairs, gates, uneven paths, and building access break the economics of curbside-only robots. Veho co-founder and CEO Itamar Zur said the partnership would test whether human-robot collaboration could improve cost, reliability, and speed.

RIVR ONE is a wheeled-legged delivery robot built for both van-dispensed and direct last-mile operation. RIVR says it carries more than 30 kilograms, reaches up to 14 kilometers per hour when needed, covers more than 30 kilometers per charge, and recharges in two to three hours. Wheels give range and speed; legs handle stairs, curbs, tight spaces, and gates.

The company began as Swiss-Mile, an April 2023 ETH Zurich Robotic Systems Lab spinout. RIVR names Marko Bjelonic, Lorenz Wellhausen, Giorgio Valsecchi, and Alexander Reske as founding team members, with research roots in wheeled-legged locomotion. Swiss-Mile raised $22 million in 2024 from investors including Amazon Industrial Innovation Fund and Bezos Expeditions before rebranding to RIVR in January 2025.

The competitive field includes Coco Robotics, Kiwibot, Serve Robotics, Starship Technologies, Cartken, Zipline, Wing, and human courier networks. RIVR's distinction is physical access: the robot is designed for the part of delivery where sidewalks end and the doorstep still has stairs, gates, or uneven ground.

The proof boundary is still pilot scale. Public material shows Veho in Austin, Just Eat in Milton Keynes, earlier Swiss Post and Migros Online work, and Amazon acquisition interest, but not parcels per hour, intervention frequency, fleet size, or delivery cost. RIVR's strategic bet is that doorstep mobility becomes valuable to a delivery network when one robot can leave the curb and complete the handoff at the door.
