OneStep, Digital Physical Therapy

What OneStep, Digital Physical Therapy does

OneStep (legally Celloscope, Inc., headquartered in New York) is a digital health company that has developed a smartphone-based motion analysis platform which extracts 30+ clinical-grade gait and mobility parameters from a patient's existing smartphone without requiring wearables, sensors, or calibration. The company's FDA-listed product, ExactStep, is registered as Software as a Medical Device under product code ISD and is supported by ISO 13485, ISO 27001, HIPAA, and GDPR certifications. The platform processes accelerometer and gyroscope data during a 30-second walk to deliver real-time insights on fall risk, balance, surgical recovery, and cognitive function, and to date has analyzed 35B+ steps across 200,000+ patients with 13 patent applications filed and 15+ research partnerships with academic medical centers including Mayo Clinic, Johns Hopkins, NYU Langone, Mount Sinai, and Dana-Farber.

The company sells to enterprise healthcare buyers across senior living, rehabilitation providers, orthotics and prosthetics, medical device companies, health systems, and research institutions. Its commercial model is subscription-based with per-clinic, per-patient, and enterprise license tiers, typically on 12-month initial terms, and the platform enables clinics to bill Remote Therapeutic Monitoring (RTM) codes for incremental revenue. OneStep monetizes through a direct enterprise field sales motion with Strategic Account Executives managing 20-30 active opportunities at health systems, payers, and risk-bearing organizations, while building SDK/API partnerships with major technology platforms, wearables, and AI/longevity products as an emerging channel.

OneStep employs 11-50 staff across its New York headquarters and a Tel Aviv engineering and R&D center. The company is private and venture-backed, having raised funding from Aleph in 2019 and Samsung NEXT's Q Fund in 2021, and has been recognized by Newsweek (World's Best Digital Health Companies 2024) and PM360 (2023 Innovator in Telehealth). The leadership team is large for the headcount, including a CEO, COO, CCO, CRO, CTO/CISO, CPO, CMO/Growth, CMO (MD), CSO, and three VPs, suggesting an enterprise-ready organizational structure despite the early-stage scale.
