Sensei Robotics
Sensei Robotics (YC S24) is a San Francisco startup building the data layer for robot learning. It pairs a sub-$300 sensorized exoskeleton arm with a distributed network of trained human operators - 'Senseis' - who perform real-world manipulation demonstrations on demand. Robotics and AI teams submit a task like folding cloth or loading a dishwasher, and Sensei returns curated, labeled human-demonstration data. The company positions itself as 'the Scale AI for robotics training data,' claiming roughly a tenth of the cost and twice the speed of conventional teleoperation setups.
Wandercraft
Wandercraft is a French robotics company that builds self-balancing walking exoskeletons and, more recently, industrial humanoid robots. Founded in Paris in 2012 by engineers - some with personal ties to degenerative mobility disease - it created Atalante X, a hands-free clinical exoskeleton now used in more than 100 rehabilitation centers, and Eve, the first self-balancing personal exoskeleton designed for home use without crutches. In 2025 the company extended its gait-control expertise into Calvin, a family of industrial humanoids developed with Renault Group and NVIDIA. Wandercraft's stated aim is to blend frontier AI with high-performance hardware to help people work and walk.
REEV
REEV is a medical robotics company building AI-powered wearable robotics to restore everyday mobility for people with neurological gait disorders after stroke, multiple sclerosis or paraplegia. Its flagship DREEVEN is a lightweight (about 3kg) motorized knee orthosis driven by electro-hydraulic actuation and real-time gait sensing, paired with REEV SENSE, an IMU wearable that turns a person's walking pattern into clinical-grade gait reports. Founded in 2021 and split between Boston and Toulouse, REEV raised $9.2M in February 2025 to finalize DREEVEN, run a clinical study at Boston University and prepare for FDA trials.
Roam Robotics
Roam Robotics builds lightweight, air-powered wearable exoskeletons that augment human strength, endurance and mobility. Founded by Ekso Bionics veteran Dr. Tim Swift, the San Francisco company replaced the heavy metal of traditional exoskeletons with plastic, fabric and pneumatic actuators - making robotic assistance cheap and light enough to wear all day. Its products span consumer skiing (Elevate), medical knee osteoarthritis relief (Ascend), and military performance (Forge), with clinical data showing 46% average knee-pain reduction and up to 2x strength and endurance gains.
