Proteus Motion

Proteus Motion, formerly known as Boston Biomotion, is a sports and healthtech startup that has developed the Proteus system—cutting-edge hardware and analytics software that fundamentally alters and improves the way athletes rehab and train.

Proteus Motion has developed intelligent strength training and rehabilitation technology, which provides users with low-impact training in an unlimited number of three-dimensional movements.

Proteus Motion was founded in 2016 by Sam Miller. The company is headquartered in Brooklyn, New York.


Proteus Motion developed a system that utilizes patented strength measurement software, which guides users through 4-minute physical assessments which deliver performance insights, while also providing a resistance training experience called 3D Resistance™ for some of the world’s top athletes.


The Proteus 3D Resistance™ is the first-ever way to accurately measure strength and power for every movement humans can perform. Currently, the company has its systems installed in 41 states and two Canadian territories.


Proteus Motion is used by a number of high-profile athletes including the MLB’s Miguel Cabrera, Giancarlo Stanton, JD Martinez and Justin Verlander, the NBA’s Damian Lillard, golf stars DeChambeau and Jon Rahm, and NFL quarterback Patrick Mahomes.


Proteus Motion is backed by Acies Investment, HBSE Ventures, Harrison & Co., Monozukuri Ventures, 412 Ventures, NBA Commissioner Emeritus David Stern, Harris Blitzer Sports & Entertainment, Special Surgery, Makers Boot Camp, and others. The company raised $8.5M in Series A round on Jul 20, 2022. This brings Proteus Motion's total funding to $15.3M to date.
