What OneStep does
OneStep (legally Celloscope, Inc., DBA OneStep), founded in 2019 and headquartered in New York with engineering operations in Tel Aviv, has built an FDA-registered smartphone-based motion-analysis platform that turns the accelerometers and gyroscopes of any consumer smartphone into a clinical-grade gait and mobility lab. The platform extracts 30+ parameters (walking speed, cadence, stride length, asymmetry, variability, balance, plus proprietary outputs such as Walk Score and Gait Age) from a 30-second walk captured passively in the patient's pocket, with results validated against gold-standard gait labs in peer-reviewed studies. Core products include the OneStep Platform (clinician dashboard plus patient-facing mobile app), ExactStep (the FDA-listed SaMD version under product code ISD), and verticalized solutions for Senior Living, Orthotics & Prosthetics, Medical Devices, Remote Therapeutic Monitoring, Rehab Providers, Health Systems, and (in roadmap) Research & Pharma.
The company monetizes primarily through SaaS subscription contracts with per-clinic, per-patient, or enterprise-license pricing, typically structured around 12-month terms with multi-year options and 6-12 month payback economics. A meaningful second revenue lever is Remote Therapeutic Monitoring billing enablement, where OneStep provides the objective mobility data required for clinics to capture RTM codes (claimed at $150/patient/month with 96% success rate). Go-to-market combines enterprise field sales targeting health systems and senior living operators, channel partnerships (an exclusive integration with Zimmer Biomet's mymobility Care Management Platform and participation in AARP's AgeTech Collaborative), and inside sales via demo-driven self-evaluation with a 6-8 week onboarding cycle.
Customer evidence spans named enterprise accounts across senior living (Signature Healthcare, Synergy Care, Ascendra Therapy, Vetter Senior Living, Blue Stone Therapy, HTS, Choice Rehabilitation), large academic medical centers (NYU Langone, Mayo Clinic, Johns Hopkins, Mount Sinai, Dana-Farber), rehabilitation providers (Select Medical / NovaCare, Prestige Rehab), and medical device partners (AposHealth, Kinomatic). The company is privately held, registered in Delaware, led by CEO Tomer Shussman, and has raised a disclosed $36M Series 2 in October 2024 led by Team8 and Vintage Investment Partners with participation from Aleph, LionBird, and 10D. Certifications stack includes FDA SaMD registration, ISO 13485, ISO 27001, HIPAA, and GDPR compliance, and 13 patent applications are filed in the motion-analysis domain.

OneStep competitors and assessment
Company assessmentBroad incumbents
- Sword Health: Sword Health delivers AI-powered digital MSK and physical therapy through employers and health plans, overlapping with OneStep's rehab and joint replacement recovery use cases at a much broader employer-sponsored distribution scale.
- Hinge Health: Hinge Health is a leading digital MSK and PT platform serving employers and health plans with virtual exercise therapy and remote monitoring—operating in OneStep's rehab/MSK space but at significantly larger scale via employer channels.
- DarioHealth: DarioHealth offers a multi-condition digital therapeutics platform including MSK, sharing OneStep's chronic-condition digital health orientation but competing less directly on gait-specific analytics.
Emerging players
- Kaia Health: Kaia Health offers app-based digital MSK and pain management programs, partially overlapping with OneStep's rehab and orthopedic recovery use cases via a self-guided rather than clinician-driven model.
Direct peers
- Kinesis Health Technologies: Kinesis QTUG provides sensor- and smartphone-based gait and mobility analysis for fall risk assessment in older adults, directly overlapping OneStep's senior living and clinical gait use cases with comparable evidence-based positioning.
- BioSensics: BioSensics develops wearable sensors and digital biomarkers for gait, balance, and fall risk in clinical trials and senior care, addressing the same fall-prevention and mobility monitoring use cases as OneStep via complementary hardware-based sensing.
- APDM Wearable Technologies (Clario): APDM, now part of Clario, offers clinical-grade wearable mobility and gait outcome assessments used in clinical trials and research, sharing OneStep's emphasis on validated gait endpoints and pharma/research customers.
- CarePredict: CarePredict uses wearable-based AI to track daily activities, mobility patterns, and fall risk in senior living residents—directly competing with OneStep's senior living fall-prevention and wellness offering via an alternative wearable form factor.
- Veristride: Veristride provides smartphone-based gait analysis for clinical and orthopedic applications, offering one of the closest direct comparisons to OneStep's BYOD motion lab approach and patient population.
Others
- Movella (Xsens): Movella (parent of Xsens) provides inertial motion capture and mobility analytics hardware/software used in clinical research and rehab—adjacent enabling technology rather than direct clinical gait SaaS competition.
