What REALTRACK SYSTEMS, S.L. does

REALTRACK SYSTEMS, S.L. is a Madrid-based Spanish technology company founded in 2008 that designs and manufactures wearable GPS performance tracking hardware for elite sports. Its core product, the WIMU Pro, is a compact athlete tracker built on a proprietary multi-sensor architecture combining four 3D accelerometers and three 3D gyroscopes, delivering location, physical, and off-ball metrics. The system is complemented by the WIMU Smart Station, a docking device with integrated PC that handles roster management, data uploads, and device provisioning, and supports real-time data transmission via the ANT+ protocol. The technology has been validated by sports scientists for use across multiple sports and gym-based physical tests including CMJ, jump, and dorsiflexion assessments.

In 2022, RealTrack was acquired by Hudl, Inc., a US-based sports analytics platform backed by Accel, Bain Capital, and Nelnet at a valuation exceeding $1 billion. The acquisition repositioned WIMU as a core component of Hudl's Athlete Performance product line, alongside Titan (an accessible-tier wearable) and Signal (a cloud-based athlete monitoring platform), and folded RealTrack's distribution into Hudl's global enterprise field sales and self-serve online channels. RealTrack generates revenue primarily through hardware sales of WIMU Pro devices and related accessories to professional sports organizations, collegiate athletics, and increasingly club-level teams, with documented deployments at Fulham FC, Palmeiras, and the Football Association of Ireland. The product is one input layer in Hudl's broader ecosystem, which combines tracking data with video analysis, AI-driven scouting (Statsbomb), and automated camera capture (Hudl Focus) across a platform serving 230,000 teams and 8 million users.
