RIVR
"Physical AI for Last-Mile Delivery."
Zurich ETH spin-off building wheeled-legged robots powered by Physical AI for autonomous last-mile and doorstep delivery; acquired by Amazon in 2026.
RIVR, founded in April 2023 as a spin-off from ETH Zurich's Robotic Systems Lab and headquartered in Zurich, Switzerland, develops autonomous wheeled-legged robots and Physical AI software for last-mile and doorstep delivery. Originally launched as Swiss-Mile, the company rebranded to RIVR in January 2025 to reflect its commercial focus. Its RIVR ONE robot combines four articulated legs with wheels, allowing it to roll at up to 15 km/h on flat surfaces and switch to walking mode to navigate stairs, curbs, and uneven terrain.
A 40-litre cargo compartment and approximately 30 km battery range enable commercial deployments. The robots are trained via reinforcement learning and physics-based simulation. RIVR partnered with Just Eat Takeaway.com for food delivery pilots in Zurich and expanded to Austin, Texas with logistics partner Veho in 2025.
The company raised a $22M seed round in August 2024, co-led by Jeff Bezos through Bezos Expeditions and HongShan. Amazon acquired RIVR in early 2026 to advance its last-meter doorstep delivery capabilities.
