One-line positioning: Global leader in inertial motion capture — the Perception Neuron series is among the most widely used inertial mocap products, now extending "human-motion digitization" into robot teleoperation and embodied-data collection.

Key facts: Founded 2012 in Beijing (founder Liu Haoyang, sensor-fusion/sports-science background per public data). Core: Perception Neuron inertial mocap lines (developer to professional), optical-inertial hybrids. Markets: film/VFX, games, sports, healthcare, industrial. Multiple rounds, unlisted.

Products & tech: Wearable IMU fusion mocap + SDKs; robot relevance: teleoperation (human-to-robot mapping), embodied data collection, exoskeleton/rehab assessment. Moat: drift-resistant IMU fusion algorithms.

Market position: Top tier globally with Xsens in inertial mocap. Investor narrative: "data gateway for embodied AI" — teleoperation is a standard training-data source for humanoids, and inertial mocap is among the cheapest, fastest-to-deploy options.
