Proteus Motion

What Proteus Motion does

Proteus Motion, founded in 2016 in New York City by Sam Miller, develops and sells a patented hardware-and-software platform for performance testing and resistance training. Its core product, the Proteus System, uses a proprietary 3D Resistance mechanism — built from steel, iron, and carbon fiber — that delivers constant resistance in all directions, enabling measurement and training across 100% of human movement patterns (including rotational and multi-planar motions that traditional cable machines and free weights cannot assess). Integrated software on a 27-inch touchscreen captures 20 proprietary metrics such as Power, Acceleration, Deceleration, Range of Motion, and the branded Proteus Score (peak power-to-bodyweight ratio), producing hyper-personalized training recommendations. Biomechanical validation is supported through a 2017 research partnership with Hospital for Special Surgery (HSS).

The company serves sports performance facilities (private, college, high school, and professional team training centers), physical therapy practices (private clinics, hospital systems, and franchises), chiropractic practices, and boutique/biohacking fitness operators, with elite individual athletes as an end-user persona. Revenue derives from hardware unit sales, recurring software/subscription services, third-party financing of systems, and ancillary testing fees at certified sites (e.g., $149 screenings, $49 re-tests). Pricing is quote-based and not publicly disclosed; distribution is direct enterprise sales plus a certified-site partner network spanning 41 US states and 2 Canadian territories — international shipping is explicitly not offered.

Go-to-market relies on enterprise field sales with website-driven demo requests, supported by content marketing (blog, research publications, case studies), a YouTube channel, the Proteus Performance Podcast hosted by Head of Performance Will Waterman, an ambassador program, and an online community platform. Notable enterprise adopters include Cressey Sports Performance, Train PMT, and individual professional athletes such as MLB pitcher Jesus Luzardo. As of mid-2022 the company had raised an $8.5 million Series A co-led by Acies Investments and HBSE Ventures, with cumulative funding across at least nine rounds totaling roughly $27 million through October 2025.

Core offering

Proteus Motion sells the Proteus System, a patented hardware device constructed from steel, iron, and carbon fiber that delivers constant 3D resistance in every direction of movement, paired with proprietary software on a 27-inch touchscreen that captures 20 performance metrics (power, acceleration, deceleration, range of motion, Proteus Score) and generates personalized training recommendations. The platform is sold primarily to sports performance facilities, physical therapy practices, and professional sports teams, with a mobile app for users and third-party financing options for hardware buyers.

Product overview

Proteus Motion offers a unified hardware-software platform centered on the Proteus System, a patented performance testing and 3D Resistance training device. The platform consists of the core Proteus System (proprietary machine with integrated software), the mobile app (iOS/Android), Proteus Teams and Proteus Live collaboration features, and the Proteus Performance Podcast. The system captures 20 proprietary metrics including Power, Acceleration, Deceleration, and Proteus Score (power-to-weight ratio), delivering comprehensive performance reports with personalized training recommendations based on normative data from over 1 million analyzed repetitions.

Direct peers

• ARX Fitness: ARX makes adaptive resistance exercise machines used in fitness, performance, and rehab settings — directly competing with Proteus on the 'intelligent resistance' core mechanic. ARX is also one of Proteus' named integration partners, underscoring how adjacent the two product philosophies are.
• Tonal: Tonal is a connected strength-training system with digital coaching and performance metrics — the closest consumer-grade analog to Proteus in combining hardware, software, and personalized training for strength/power development.
• Tempo: Tempo offers a connected strength-training system with form feedback, 3D sensors, and a subscription coaching layer — competing head-to-head with Proteus in the data-driven strength training category, though at lower price points and aimed more at home users.

Broad incumbents

• Keiser: Keiser manufactures pneumatic resistance equipment widely used in professional sports, physical therapy, and clinical rehab — overlapping Proteus' customer base and use cases (functional, low-impact resistance training), though without Proteus' 3D multi-planar mechanism.
• Eleiko: Eleiko is a well-established Swedish manufacturer of professional strength training and performance equipment used in elite sports facilities and competitions. It competes for the same facility budgets and floor space as Proteus, though its portfolio is broader and more traditional.
• Peloton: Peloton is the largest connected fitness platform with hardware plus subscription; while focused on cardio and bike, its strength training push and large installed base make it a broad competitive threat in data-driven connected strength.
• Whoop: Whoop is a subscription-based wearable performance and recovery platform used by the same elite athlete and trainer demographic as Proteus. It overlaps with Proteus' integrations ecosystem and competes for athlete-level performance data ownership.
• HUR: HUR manufactures computerized pneumatic strength training equipment with performance tracking, widely deployed in physical therapy, senior fitness, and rehabilitation — overlapping Proteus in PT/rehab use cases and software-driven testing, but with a narrower performance-sports positioning.

Regional players

• Hudson Strength: Hudson Strength designs and manufactures innovative strength and rehab equipment, including specialized functional training devices — comparable to Proteus on the equipment side for physical therapy and sports performance facilities, though with a more traditional resistance modality.

Emerging players

• VALD Performance: VALD Performance builds force plate, dynamometer, and human measurement systems used by professional sports teams and PT clinics — competing with Proteus for the 'objective performance measurement' budget at elite facilities, though with a different (force-plate-based) measurement modality.
