RIVR scores B on the Alion truth index (A is best, E worst), measured over 32 open roles re-checked against its own hiring board: 38% look like ghost listings, 0% have gone stale and 0% are the same role posted again. Its roles close in a median of 96 days. It measures how much of what this employer publishes turns into a real, finite search - not the employer as a workplace. How the index is computed
Overview
RIVR (formerly Swiss-Mile, legally incorporated in Zurich, Switzerland) is a physical AI and autonomous robotics enterprise spun out of ETH Zurich's Robotic Systems Lab. Founded in 2023 by Marko Bjelonic, Lorenz Wellhausen, Giorgio Valsecchi, and Alexander Reske, the venture raised over $26 million from high-profile backers including Bezos Expeditions and the Amazon Industrial Innovation Fund, before being acquired by Amazon in March 2026.
