Amazon has acquired Zurich-based robotics startup Rivr, known for its stair-climbing, four-legged delivery robots on wheels. The deal, finalized in March 2026, strengthens Amazon’s push into doorstep delivery automation, though financial terms remain undisclosed.
Rivr is a Zurich-based robotics startup founded in 2023 by Alexander Reske, Marko Bjelonic, Giorgio Valsecchi, and Lorenz Wellhausen. The company focuses on building “General Physical AI” through robots that combine legs and wheels, enabling them to climb stairs, navigate uneven terrain, and deliver packages directly to doorsteps. Their technology addresses the “last 10 yards” problem in logistics, making deliveries more efficient in dense urban environments and multi-story buildings.

Backed by investors such as Bezos Expeditions, Linear Venture, and HSG Ventures, Rivr raised around $25–26 million in funding and was valued at approximately $100–110 million before its acquisition by Amazon in March 2026. With Amazon’s resources, Rivr’s stair-climbing robots are expected to scale globally, extending automation beyond warehouses into last-mile delivery, while also tackling challenges of urban regulation, public acceptance, and large-scale deployment.
Beyond Rivr, Amazon has recently made acquisitions in aerospace, AI, and logistics to strengthen its infrastructure and automation capabilities. The most notable moves include investments in aerospace ventures and AI-driven platforms as part of its $200 billion pivot into next-generation technologies.
Alongside Rivr, Amazon has been expanding its robotics portfolio with warehouse automation startups and delivery-focused robotics firms. These acquisitions complement Rivr by extending automation from warehouses to last-mile delivery.
