Modus Health

What Modus Health does

Modus Health, LLC is a privately held medical device and software company headquartered in Mountlake Terrace, Washington, that develops the StepWatch Activity Monitor, an FDA-listed and CE-marked research-grade wearable for precise measurement of walking activity in patients with slow or irregular gait. The company's technology stack centers on a proprietary walking algorithm validated across more than 600 peer-reviewed publications and 40+ patient conditions, paired with three software modules — Clinical Care, Clinical Trials, and Research — that enable clinicians and researchers to set personalized mobility goals, monitor progress, and use StepWatch as a validated digital endpoint for pharmaceutical studies. StepWatch is currently in its fifth hardware generation, which is half the size and weight of the prior generation with faster manufacturing scalability.

Modus Health generates revenue through a combination of hardware sales of StepWatch devices, recurring software subscriptions for its Clinical Care platform, and clinical-trial technology services that supply validated activity-monitoring endpoints to pharmaceutical and medical-device sponsors. Its go-to-market is direct enterprise sales to healthcare systems, research institutions, and pharma trial sponsors, with named deployment customers including Intermountain Health (expanded from 1 to 16 clinics), DCH Health System, and CatoSenteret in Norway. The company distributes across 145 clinical sites in 71 countries and is used as the gold-standard benchmark by Google, Fitbit, and Samsung Digital Health for validating their consumer fitness monitors.

The company traces its origin to StepWatch development begun by Dr. Ernest M. Burgess in the late 1980s at the Prosthetic Research Study, evolved through Cyma Corporation (1995) and Orthocare Innovations (2007), and was incorporated as Modus Health, LLC in 2013 to focus exclusively on activity monitoring. Leadership includes CEO and President Teri Rosenbaum-Chou, PhD, CTO Chris Green (an original founding employee and former first employee of $1.1B-exit CoverMyMeds), and a Scientific Advisory Board of PhD-level clinical researchers, with Dr. Amir Lahav of SkyMedAI joining the Advisory Board in March 2025 to accelerate clinical-trials and healthcare expansion.

Expansion highlights5 records

Direct peers

• ActiGraph: ActiGraph is the dominant provider of research-grade wearable activity monitors for clinical trials and academic research, offering accelerometry-based devices with FDA-cleared software. It directly competes with Modus in the clinical trials and research endpoints market.
• Vivonoetics (formerly VivoSense): Vivonoetics provides wearable sensor analytics and validated digital endpoints for clinical trials and pharmaceutical research, partnering with device OEMs including ActiGraph. It directly competes with Modus's Clinical Trials software offering for mobility endpoint validation.

Emerging players

• Empatica: Empatica makes FDA-cleared medical-grade wearables (EpiMonitor for epilepsy, Embrace) used in clinical trials and neurological conditions. It overlaps with Modus in clinical trial digital endpoints and patient monitoring, but focuses on autonomic/EEG signals rather than gait.
• Oura: Oura's smart ring tracks activity, sleep, and recovery and is being validated in clinical research partnerships. It is an emerging player in the health wearable and clinical research endpoint space, with consumer-led distribution.

Broad incumbents

• Medidata (Dassault Systèmes) - BioStamp: Medidata's BioStamp and Sensor Cloud platform offers wearable-based digital endpoints for clinical trials at scale as part of its broader CRO/clinical technology stack. It competes with Modus in pharma trials but with substantially larger distribution and integration capabilities.
• Garmin Health: Garmin Health provides wearables and APIs for clinical research and population health studies. It competes in the activity-monitoring and clinical trials space but focuses on healthier populations and broader consumer fitness use cases.
• Fitbit (Google): Fitbit, owned by Google, is a major consumer wearables brand now being positioned for health and clinical applications. It is named in Modus's data as a benchmark user of StepWatch, reflecting an indirect competitive and validation relationship.
• Apple (Apple Watch Health): Apple Watch has FDA-cleared health features (ECG, AFib detection) and is increasingly used in clinical research as a wearable endpoint. It competes indirectly with Modus in clinical monitoring and as a potential alternative endpoint in research.

Others

• Withings: Withings produces connected health devices (scales, watches, sleep monitors) and has moved into clinical-grade health monitoring. It is adjacent to Modus in connected health devices but lacks focus on impaired-gait populations.

Regional players

• iHealth Labs: iHealth Labs provides connected health monitoring devices (BP, glucose, wearables) with FDA clearances, primarily for consumer and telehealth channels. It is thematically adjacent to Modus in connected medical devices but with a different patient focus.
