RIVR is an innovative Swiss robotics company that is transforming the landscape of last-mile delivery through its pioneering Physical AI technology. By combining artificial neural networks with a unique wheeled-legged robot design, RIVR aims to tackle one of the most challenging aspects of urban logistics: the final few steps from delivery vehicles to customers’ doorsteps. Founded initially as Swiss-Mile and rebranded to RIVR in 2025, the company is backed by prominent investors, including Jeff Bezos. Their groundbreaking robots, capable of navigating stairs, curbs, and complex urban terrains with dexterity and autonomy, promise enhanced efficiency, sustainability, and scalability, giving one human the power of a thousand robots. This article explores ten key aspects of RIVR, unveiling its journey, technology, partnerships, and vision for the future of delivery.
RIVR originated as Swiss-Mile, a spin-off from ETH Zürich founded in 2023 by experts in robotics and Physical AI. The company initially focused on developing cutting-edge robotic solutions to revolutionize last-mile delivery, an area known for inefficiencies and high operational costs. In early 2025, the company rebranded to RIVR to better reflect its expanding mission to reinvent autonomous urban logistics and robotics. This marked a strategic shift from a university spinoff to a global leader prepared to deploy delivery robots on a large scale, setting sights on deploying over one million units worldwide.
RIVR’s core innovation lies in its implementation of Physical AI, a convergence of artificial intelligence with robotic embodiment that enables machines to perceive, learn, and act in complex physical environments autonomously. Unlike traditional AI, which largely focuses on software intelligence, Physical AI integrates sensory data, reinforcement learning, and real-world interaction capabilities. RIVR’s robots leverage these advancements to interpret diverse urban scenarios—climbing stairs, traversing uneven terrain, and navigating gates—tasks that have traditionally challenged robotic systems, thus enabling truly autonomous doorstep deliveries.
RIVR’s signature robots combine the efficiency of wheels with the versatility of legs. This hybrid design offers the energy efficiency and speed of wheeled locomotion on smooth surfaces, while the articulated legs provide the necessary dexterity to climb stairs, step over obstacles, and manage uneven terrain. Their robots are equipped with advanced sensors, including cameras and LiDAR, and a robotic arm for placing packages precisely. This unique kinematic configuration allows RIVR’s delivery bots to operate in complex residential environments, delivering parcels directly to customers’ doors rather than to the curbside as with many other delivery bots.
RIVR trains its robots using a combination of reinforcement learning in simulated environments and supervised learning from real-world data. Their proprietary simulation platforms create realistic, game-like training worlds that accelerate robot learning cycles over days rather than months. Real-world data gathered from expert interventions further refines the robots’ decision-making capabilities. This dual learning approach fuels a data flywheel effect, where each deployment enhances overall robot intelligence and autonomy, enabling a fleet to grow with fewer remote interventions and greater operational robustness.
RIVR has forged strategic collaborations with leading logistics companies to field-test and deploy its robots. In the United States, it partnered with Veho, a prominent parcel delivery platform, to launch commercial deliveries in Austin, Texas. The robots assist human drivers by managing the last 100 yards of delivery, simultaneously improving throughput, reducing physical strain on drivers, and enhancing customer experience through precise delivery placement and photo confirmation. In the United Kingdom, RIVR teamed up with Evri, the largest dedicated parcel delivery company, to deploy its wheeled-legged robots in Barnsley, South Yorkshire. These partnerships underscore RIVR's commitment to integrating robotics into real-world logistics workflows.
One of the greatest challenges in e-commerce logistics is the last-mile delivery segment, specifically the final 100 yards from delivery vehicle to customer doorstep, often cumbersome, labor-intensive, and costly. RIVR’s technology addresses this bottleneck by automating these short-distance deliveries with autonomous robots capable of navigating complex urban obstacles. This approach not only frees drivers to cover more ground but also helps reduce delivery times, operational costs, and environmental impact through increased efficiency and sustainability.
RIVR’s robotic fleet is designed with sustainability in mind. Their wheeled-legged design offers significant energy savings compared to purely legged robots, enabling greater range and battery life. By increasing delivery efficiency, RIVR helps reduce carbon emissions associated with multiple delivery attempts and inefficient route planning. The scalable deployment of robots supports greener urban logistics, alleviating congestion and emissions, vital in the context of explosive e-commerce growth worldwide.
Since its rebranding, RIVR has raised over $22 million in seed funding, including investment from high-profile backers such as Jeff Bezos through Bezos Expeditions, and HSG. This substantial financial backing reflects investor confidence in RIVR’s technology and market potential. RIVR’s innovations have gained significant media exposure with over 100 million views and coverage in major technology and business outlets. The company is widely recognized as a pioneer in Physical AI-driven robotic logistics and continues to attract top talent and strategic partners.
Initial trials in Austin demonstrated that RIVR robots successfully delivered parcels directly to customers’ doorsteps, climbing stairs and navigating difficult terrain, tasks that are typically challenging for traditional delivery robots. Veho reported that robots working alongside human drivers improved delivery reliability, speed, and reduced physical strain on personnel. The pilot's success has spurred plans for expansion into additional U.S. markets and international rollouts. Continuous data collected during these deployments is refining robot algorithms and operational efficiency.
RIVR envisions a future where its fleet of one million delivery robots operates globally, seamlessly integrated into urban logistics ecosystems. Their mission extends beyond parcel delivery to enabling general Physical AI for urban mobility, potentially expanding robotic assistance across multiple industries. By solving the “last 100 yards,” RIVR aims to create a scalable data flywheel, accelerating robotic intelligence and autonomy. Their approach could redefine labor dynamics in logistics, focusing on augmentation rather than replacement, and spearheading the next wave of automation with a human-centered ethos.
RIVR represents the cutting edge of robotics applied to a critical challenge in urban logistics—the last-mile delivery problem. With its revolutionary Physical AI-powered robots, combining sophisticated artificial intelligence with an innovative wheeled-legged design, RIVR is changing how parcels reach customers’ doors. Their emphasis on sustainability, human collaboration, and real-world deployment partnerships illustrate a technology maturing beyond the prototype phase toward scalable impact. As e-commerce demand escalates globally, RIVR’s vision to deploy massive fleets of autonomous delivery robots offers a glimpse at the future of efficient, sustainable, and human-centered logistics. The company’s progress raises intriguing possibilities: How will Physical AI reshape urban living and labor? Will RIVR’s robots become ubiquitous on sidewalks worldwide? Only time will tell, but their pioneering efforts position them at the frontier of this logistics revolution.
