Not Another Demo: A European Startup Is Already Running Daily Delivery Routes With Legged Robots
RIVR, a Swiss robotics company founded in 2023 by ETH Zurich PhD Marko Bjelonic and four co-founders, is deploying wheel-legged robots for last-mile delivery in Zurich, Leeds, Austin, and Boston — partnering with major logistics players including Evri (UK), Veho (U.S.), and Just Eat Takeaway (Europe).
Unlike most robotics startups still chasing viral videos, RIVR is generating real revenue from operational tasks:
- 60–100 packages per robot per day
- ~20 food deliveries daily
- 5–6 hours of runtime
- 30 km range, 15 km/h top speed
- 60 kg payload, 40L cargo volume
The company expects to complete tens of thousands of deliveries by end of 2025 — a rare example of commercial-scale deployment in embodied AI.

The Tech Edge: Wheel-Leg Hybrid + AI-Native Control
RIVR’s robots combine wheels for speed on flat ground and legs for stairs, curbs, and uneven terrain — a design pioneered by Bjelonic during his PhD at ETH Zurich’s Robotic Systems Lab. He was the first to apply artificial neural networks to wheel-legged locomotion.
The system is AI-native, not AI-enhanced:
- Perception, navigation, and decision-making are handled by a custom neural network trained on real-world delivery data
- No pre-programmed routes — robots adapt to dynamic obstacles (e.g., pets, children, pedestrians)
- Environmental awareness enables behaviors like waiting for students to cross or rerouting around construction
“We’re not building ‘something plus AI,’” said Gus Leung, RIVR’s China Supply Chain Lead.
“We’re building a product where AI is the soul — and the body is designed around it.”

The Business Model: Solving a Clear Economic Problem
RIVR bypassed industrial and security applications — saturated with repetitive, low-value data — and targeted last-mile delivery, where:
- Labor costs are high (U.S./Europe: $15–25/hour per courier)
- Routes are sparse (especially in suburban/villa districts)
- Even a $0.60 reduction per delivery yields immediate ROI
The company started in low-density, high-income neighborhoods — easier navigation, fewer obstacles, higher willingness to adopt tech.
Operational refinements reflect real-world pragmatism:
- Fluorescent wheels and body lights for night visibility
- Dual IoT SIM cards to ensure connectivity in areas with poor U.S. cellular coverage
- Remote assist mode allowing human operators to request help from bystanders if needed
These aren’t research features.
They’re customer-driven product decisions.

Going Global from Day One — With a China Supply Chain Play
Founded in Switzerland (population: 8M), RIVR was built to scale globally from the start:
- U.S. and Europe: Commercial operations and customer acquisition
- China: Supply chain and hardware integration
Gus Leung, a former NIO (NIO Inc.) early employee and co-founder of Front Journey Automotive, joined to lead China operations. His thesis:
Robotics and EVs share the same foundational stack: perception, planning, control, and supply chain.
RIVR is now building a vertically integrated production system in China, leveraging the same supplier ecosystem that enabled China’s EV boom.
“Everyone in the supply chain is betting on the next Tesla,” said Leung. “Now they’re betting on the next RIVR.”

Backed by Bezos — Because It Solves a Real Problem
RIVR has raised $26 million to date from:
- Bezos Expeditions (lead, Series A)
- Sequoia China
- Linear Capital
- Agile Robots (SI灵)
Valuation reached $100 million after its 2024 angel round.
Investor logic is clear:
- Team: World-class robotics pedigree (ETH Zurich, Mercedes-AMG, Fraunhofer)
- Tech: Proprietary AI framework that can train a new neural network for any robot hardware in one week
- Commercial discipline: Revenue from day one, not grants or demos
“Bezos invested because the robot delivers value — literally,” said a source familiar with the deal.
Marko Bjelonic initially thought Bezos’s outreach was spam. Their 30-minute call stretched to 60. By the end, Bezos had committed to lead the round.

Roadmap: Thousands of Units Across 10+ Cities by 2026
RIVR plans to:
- Expand to 10+ cities in North America and Europe in 2026
- Deploy thousands of units
- Explore partnerships with Chinese autonomous driving firms for integrated last-mile solutions
The company acknowledges challenges:
- Design: Making robots more approachable (softer aesthetics)
- Environment: Moving beyond villas into high-rises and dense urban areas
- Autonomy: Current operations include remote oversight; full autonomy remains a work in progress
But its philosophy is grounded:
“In robotics, technology is globally flat — like autonomous driving,” said Leung.
“What matters isn’t who has the best algorithm. It’s who lands first and creates real user value.”
RIVR isn’t waiting for the future.
It’s delivering it — one package at a time.
