What VERT does

VERT (legal entity Mayfonk, LLC, dba VERT, formerly Mayfonk Athletic) is a Fort Lauderdale-based sports technology company founded in 2013 that builds wearable inertial measurement unit (IMU) sensors and team analytics software for athlete load management, injury prevention, and vertical jump performance testing. The flagship VERT 3 sensor is a thumb-drive-sized IMU containing a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer that clips to an athlete's waistband and streams data over Bluetooth Low Energy to a paired iOS app; a proprietary algorithm runs 53 simultaneous calculations at a 3,000 Hz sampling rate to measure center-of-mass vertical displacement, jump count, and landing impact (with alerts above 15G flagged as elevated injury risk). Independent University of Calgary validation placed the device within less than 1 inch mean error versus a Kintrak 3D motion analyzer. The platform is protected by 11 U.S. patents and a registered VERT trademark.

The commercial model is a tiered mix of hardware and recurring software. Individual athletes buy the VERT 3 sensor for $199.99 plus a $6.99/month app subscription, while teams buy the VTS Basic analytics platform at $100 per sensor per year (supporting up to 16 athletes in real time on iPad with Acute-to-Chronic workload ratios), the budget-oriented VERT Essential Package at $599.98 with 2 sensors, or the high-touch VTS Advanced tier with custom pricing that bundles a dedicated Performance Lab team of exercise scientists and former D1 coaches. Accessories (belts, clips, chargers) and product certification services (e.g., certifying the RIP-IT FUTURE volleyball shoe) add ancillary revenue. Distribution runs through direct e-commerce (myvert.com, myvert.eu), Amazon marketplaces, certified international resellers in Canada, Europe, and Japan, and direct enterprise sales. The customer base is anchored in NCAA Division I, II, and III volleyball programs and national federations (USA Volleyball is an official partner, with logos from Penn State, Florida, Mississippi, Stanford, UNC, UCF among others), with growing exposure to basketball (Miami Heat, Auburn) and a global footprint claimed across 100+ countries.

Core offering

VERT sells a wearable IMU sensor (VERT 3) and accompanying iOS app that track jump count, jump height, and landing impact for athletes, paired with the VERT Team System (VTS Basic, VTS Advanced, and Essential Package) analytics platforms for teams. The offering bundles hardware, mobile software, team dashboards with Acute-to-Chronic workload ratios, and a Performance Lab service for collegiate and professional programs, plus consumer subscriptions and a third-party product certification program.

Product overview

VERT offers a player load management and injury prevention system centered on wearable IMU (inertial measurement unit) technology. The core product is the VERT 3 wearable sensor, which athletes wear clipped to their waistband to track jump count, jump height, and landing impact metrics in real-time. The system operates through a tiered platform structure: VTS Basic provides entry-level team analytics for up to 16 athletes with iPad tracking, VTS Advanced offers full-service performance lab reporting with dedicated analytics support, and the Essential Package provides budget-accessible entry with 2 sensors. Individual athletes use the VERT App with monthly subscription for personal performance tracking. Accessories include belts, chargers, and clips. VERT also offers a certification program for third-party products and has certified RIP-IT volleyball shoes based on landing impact testing. The company serves over 500 collegiate, national, and professional programs across 100+ countries.

Scale indicators8 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Garmin: Garmin offers a broad portfolio of GPS fitness watches, heart-rate monitors, and sport-specific wearables used by athletes. Its mass-market scale and bundle pricing make it a credible substitute for VERT's individual athlete and prosumer segments.
• WHOOP: WHOOP is a subscription-based wearable that tracks strain, recovery, and sleep for athletes. While positioned for individual use rather than team-based load management, it competes for the same individual athlete customer that buys VERT's $6.99/month subscription.
• Polar Electro: Polar is an established manufacturer of heart-rate monitors, fitness wearables, and team sport sensors. It serves a broader consumer and team market than VERT, but its Ignite/Vantage lines and team sport solutions overlap with VERT's wearable sensor proposition.
• Zephyr (now part of Medtronic): Zephyr's BioHarness and physiological monitoring modules have been used for athlete load and exertion monitoring. As a broader medical/military biometrics player, it overlaps with VERT's IMU-based monitoring capability in research and elite training contexts.

Direct peers

• Kinexon: Kinexon offers real-time athlete and ball tracking using UWB and wearable sensors for basketball, soccer, and team sports. It overlaps with VERT in objective athlete load and performance analytics for professional and collegiate programs.
• Catapult Sports: Catapult is a leading provider of wearable athlete tracking technology (IMU/GPS) used by elite and professional teams globally. It is the most direct competitor to VERT's player load management system, with overlapping sports science analytics and team subscription offerings.
• STATSports: STATSports provides GPS- and IMU-based wearable athlete monitoring for soccer, rugby, GAA, and other team sports. Its Apex and Sonra products directly compete with VERT's VTS platform in the team load-management category.

Emerging players

• Playermaker: Playermaker produces wearable trackers that strap to soccer boots to measure kick count, speed, and load. It is an emerging player applying similar wearable IMU concepts to a different sport vertical, demonstrating the broader applicability of VERT's approach.
• Hammerhead (Wearable Sports Technology / Push): Push (formerly Catapult Push) offers wearable sensors measuring force, power, and load during training. It overlaps with VERT in strength/conditioning-style athlete monitoring and addresses adjacent use cases such as rehabilitation.

Others

• Kistler (force plates / biomechanics): Kistler manufactures high-precision force plates and 3D motion capture systems referenced alongside VERT in validation studies. It is not a direct competitor at the consumer/team price point but represents the gold-standard biomechanics alternative that VERT undercuts.
