What Nextiles does
Nextiles is a Brooklyn-based materials science company founded in 2018 that builds a fabric-based sensor platform for capturing biomechanical and biometric data. Its core technology uses patented semi-conductive threads sewn into compression garments to measure force, bending, stretching, pressure, and velocity across the fabric surface, combined with a detachable Bluetooth module that streams data at 100+ Hz. The product portfolio includes three hardware SKUs — the Arm Sleeve ($199), the Knee Sleeve ($199), and the Fabric Force Plate ($650) — paired with a mobile app, web dashboard, and enterprise platform.
The company operates four go-to-market motions in parallel: direct-to-consumer e-commerce, enterprise field sales to professional and collegiate sports organizations, channel partners (training facilities and physical therapy providers such as Connected Performance, Helix PT, and Tom House Sports), and OEM/white-label licensing (e.g., the KineticPro Sleeve powered by Nextiles sensors and integrated via SDK into partner apps such as 6-4-3 Charts and Connected Performance). Revenue is generated through one-time hardware sales, subscription software and enterprise platform fees, and licensing royalties from OEM partners. Strategic investors include Drive by DraftKings (seed lead), the NBA, Madison Square Garden Sports, and SBIR grants from the National Science Foundation and the U.S. Air Force. In May 2026, Nextiles was acquired by Betterguards, with founder George Sun joining as CTO to combine both companies' injury-prevention and performance-monitoring technologies.

Nextiles product offering
Product offeringCore offering
Nextiles designs and manufactures smart fabric wearables—Arm Sleeve ($199), Fabric Force Plate ($650), and Knee Sleeve ($199)—with patented semi-conductive thread sensors sewn directly into compression garments to capture real-time biomechanical and biometric data (force, pressure, strain, velocity, torque, motion). Data streams via Bluetooth to a paired mobile app, web dashboard, and enterprise platform, where AI-powered personalized intensity zones and team management tools convert raw sensor output into actionable insights for coaches, athletes, and sports organizations. The platform also exposes APIs and SDKs for partner integrations and white-label OEM products such as the KineticPro Sleeve.
Product overview
Nextiles is a materials science company that has developed a unified fabric-sensor platform combining patented fabric-based sewing technology with data analytics software to measure human performance. The product portfolio consists of three hardware products (Arm Sleeve, Fabric Force Plate, and Knee Sleeve) and an integrated software ecosystem comprising mobile app, web dashboard, and Enterprise platform. All hardware products feature embedded fabric sensors that capture biomechanical and biometric data (forces, velocity, torque, pressure, motion) and transmit data in real-time via Bluetooth to the software platform. The software provides real-time monitoring, historical trend analysis, and AI-powered insights (Personalized Intensity Zones) for coaches and athletes to optimize performance, manage workload, and prevent injuries. The company offers SDK and API access for partner integrations with platforms like 6-4-3 Charts, Connected Performance, and KineticPro.

Nextiles competitors and assessment
Company assessmentDirect peers
- WHOOP: WHOOP is a leading wearable fitness and recovery band that captures biometric data (HRV, sleep, strain) via a strap-based form factor. It is a direct peer because both compete in athlete biometric monitoring with subscription-based software layered on hardware, although Nextiles differentiates through fabric-embedded sensors versus a wrist strap.
- Catapult Sports: Catapult provides wearable athlete tracking and performance analytics used by professional and collegiate teams globally. It is directly comparable as a team-facing sports wearable + analytics platform, though Catapult focuses on GPS/IMU vests rather than fabric-embedded sensors.
- Motus Global (now part of Driveline Baseball): Motus Global pioneered the compression-sleeve baseball arm-health sensor (mThrow) for pitchers. It is the closest direct peer to Nextiles' Arm Sleeve, both targeting pitcher workload, elbow torque, and arm health for MLB, NCAA, and travel ball organizations.
- KinaTrax: KinaTrax provides markerless motion-capture biomechanics for professional baseball pitchers. It is comparable because both companies sell biomechanical pitching analytics to MLB teams, though KinaTrax uses optical tracking rather than fabric sensors.
- Playermaker: Playermaker makes foot-mounted smart insoles that capture athletic metrics (speed, kicks, power) for soccer, football, and other sports. Comparable as a sensor-embedded athletic wearable + analytics platform, though targeted at the foot rather than arm/knee.
- STATSports: STATSports builds GPS-based athlete tracking vests used by elite soccer and field sports teams. Comparable as a team-facing athlete monitoring wearable + analytics platform, though STATSports' core is GPS/IMU tracking rather than fabric force analytics.
- Blast Motion: Blast Motion makes baseball/softball swing and pitch sensors used widely in travel ball, college, and MLB. Comparable as a baseball-focused athletic sensor + analytics company, though Blast's form factor is a small clip-on sensor rather than a fabric sleeve.
Broad incumbents
- Polar Electro: Polar is a long-established sports wearable brand offering heart-rate monitors, GPS watches, and team-sport tracking. Comparable as a broad sports wearables incumbent, but its products are watch/strap-based rather than fabric-embedded sensors.
- Garmin: Garmin is a dominant sports and fitness wearables incumbent with deep distribution and team-sport analytics offerings. Comparable as a broad incumbent in athletic wearables, but its core is wrist-based GPS watches rather than compression-fabric sensor garments.
Emerging players
- Zepp Health (Amazfit): Zepp Health develops AI-powered sports wearables and analytics platforms, including baseball/softball swing sensors. Comparable as an emerging sensor + analytics company in athletic performance, though Zepp focuses on wrist and clip sensors.
