Amazon Acquires Swiss Robotics Start-Up Rivr in Major Tech Deal
Global retail giant Amazon has acquired the Zurich-based delivery robot start-up Rivr. The ETH Zurich spin-off, known for its four-legged robots capable of climbing stairs, marks another significant Swiss tech success story and a major investment by a global giant.

Global retail titan Amazon has officially swallowed Zurich-based innovation, acquiring the delivery robot start-up Rivr in a move that underscores Switzerland's dominance in the tech sector. This is not merely a purchase; it is a conquest of superior engineering. The ETH Zurich spin-off, formerly known as Swiss-Mile, has rapidly ascended from a university project to a global asset, boasting a staggering valuation of nearly $110 million (CHF 86 million) as recently as 2024.
Rivr CEO Marko Bjelonic broke the silence, confirming the deal on LinkedIn, though the exact price tag of this final acquisition remains shrouded in corporate secrecy. This acquisition signals a critical shift: Amazon is no longer just looking for automated warehouses; they are aggressively targeting the 'last 50 feet' of delivery—the stairs and doorsteps that baffle conventional wheeled drones. With this bold move, Amazon secures a direct pipeline to some of the finest engineering minds in Europe, cementing Zurich's reputation as a non-negotiable hub for future tech.
Defying Gravity: The Hybrid Solution
These machines do not just roll; they evolve. Rivr's robots represent a dramatic leap forward in autonomous logistics, shattering the limitations of traditional delivery bots. By ingeniously combining wheeled efficiency with four-legged agility, these mechanical couriers can traverse flat pavements at speed before transforming to climb stairs and navigate complex, rough terrain.
While competitors' robots remain trapped on the sidewalk, Rivr's technology conquers the vertical obstacles of urban living. This hybrid mobility is the "holy grail" for logistics giants like Amazon, desperate to automate the final, most expensive leg of the delivery journey. The technology, born in the prestigious labs of ETH Zurich, demonstrates a level of versatility that standard wheeled rovers simply cannot match. This is not just an upgrade; it is a complete reimagining of how goods move through a three-dimensional world.
Bezos Bets Big on Zurich
The writing was on the wall long before the ink dried on the acquisition contract. Jeff Bezos, through his personal investment company, had already identified the potential in this Swiss start-up, pouring capital into Rivr alongside Amazon's own Industrial Innovation Fund. This was a calculated, long-term play by the world's most aggressive retail strategists.
By investing early, Bezos and Amazon effectively ring-fenced this critical technology, ensuring that when the time was right, they would be the ones to control it. This pre-existing financial entanglement suggests that Amazon viewed Rivr not as a gamble, but as an inevitability. The acquisition validates the foresight of early investors who recognized that the future of delivery would be built in Zurich, not Silicon Valley.
