PhyxUp Health Raises $1 Million Seed Round to Expand AI-Powered Remote Rehabilitation Platform

PhyxUp Health, a San Francisco–based AI-driven remote therapeutic monitoring (RTM) platform, has raised $1 million in seed funding to accelerate its U.S. expansion and deepen product innovation in the fast-evolving digital rehabilitation market. The investment will help the company enhance its AI-powered monitoring technology, grow its commercial footprint, and support physical therapy clinics and hospitals in delivering continuous between-visit patient care more effectively.

The seed round was led by Korea Investment Accelerator, a Seoul-based startup accelerator and early-stage investor that helps technology-driven companies grow and scale through structured acceleration programs, mentorship, and capital support. Korea Investment Accelerator’s participation underscores growing international investor confidence in PhyxUp Health’s approach to modernizing rehabilitation care with data-driven, automated solutions.

Participating in the round was Synergy IB Investment, an investment firm based in Seoul with experience in funding technology and innovation-oriented startups. Synergy IB Investment’s backing reflects strategic interest in PhyxUp’s potential to reshape clinical workflows and outcomes in physical therapy and related healthcare sectors.

The funding complements earlier support PhyxUp Health received from investors in its pre-seed round, including DHP (Digital Healthcare Partners) and Rabbit VC, which provided capital during the company’s formative phase as it built its initial product and market momentum. These early backers helped position PhyxUp to pursue broader commercial growth and engage larger U.S. healthcare markets.

Founded in 2023 by CEO Sangwon Lim, a former physical therapist and Harvard graduate, PhyxUp Health delivers a B2B SaaS platform that enables clinics and rehabilitation providers to remotely monitor patient progress using AI-powered analytics. The platform is designed to increase therapy adherence, streamline administrative tasks, and unlock new reimbursement opportunities through automated documentation and billing compliance, particularly for Medicare Remote Therapeutic Monitoring CPT codes introduced in recent years.

PhyxUp’s technology analyzes patient health and exercise data in real time, providing clinicians with actionable insights for early risk detection and more informed treatment adjustments between visits. Its fully managed RTM service combines automation with licensed clinical oversight, helping clinics boost both patient outcomes and operational efficiency.

The company is already gaining traction across the United States, with adoption spanning independent private practices, multi-location clinic networks, and hospital-affiliated outpatient departments. Notably, PhyxUp’s platform is in use at institutions affiliated with Harvard Medical School, and the company has collaborated with research partners such as the Marcus Institute for Aging Research to refine its AI capabilities and clinical credibility.

PhyxUp Health’s seed funding will support the company’s nationwide expansion as more rehabilitation providers transition to digitally enabled care models that emphasize continuous patient engagement and outcomes tracking. The capital is expected to accelerate go-to-market efforts, expand partnerships with practice management systems, and enhance the platform’s predictive and risk-stratification capabilities.

In addition to product development and sales growth, the company aims to use the funding to strengthen integrations with electronic medical record (EMR) systems, improve interoperability, and broaden its automated billing and reimbursement workflows. This expansion is key to helping clinics unlock consistent revenue from RTM services while reducing administrative burdens that historically slow clinical adoption of new digital tools.

Industry observers have noted that the U.S. remote therapy market is substantial and growing rapidly, with telehealth adoption surging since the COVID-19 pandemic and ongoing demand for digital care solutions that extend beyond traditional clinic settings. PhyxUp Health’s seed raise positions it to capitalize on these trends by delivering tools that both improve patient experience and drive measurable clinical value for providers.

CEO Sangwon Lim has emphasized that the company’s RTM platform is intended to reduce inefficiencies and administrative burdens within outpatient rehabilitation settings, enabling therapists to focus more on patient care and less on paperwork. By combining clinical expertise with automated analytics, PhyxUp seeks to play a central role in upgrading the infrastructure of rehabilitation healthcare across the U.S.

As PhyxUp Health continues its growth trajectory, the company looks toward future product innovations and strategic partnerships that further solidify its position as a leading AI-powered RTM provider in the digital health ecosystem.
