Summary
Flagler Health, a New York-headquartered AI-native platform for musculoskeletal healthcare, announced it raised a $50 million Series B, according to a Business Wire release dated August 11, 2026. The round was led by Bessemer Venture Partners and included participation from SignalFire, Alumni Ventures, Streamlined, 186 Ventures, Proof VC, Tribeca Venture Partners, and Offscript. Total funding raised by the company now stands at $63 million.
The company positions its product as an operating system for MSK clinics, a segment it describes as the largest and most underserved specialty in healthcare. The release cites figures that musculoskeletal conditions affect more than half of U.S. adults and account for over $400 billion in annual healthcare spend, and that physicians spend nearly 75 percent of their time on non-revenue-generating work. Flagler's platform is trained on what it describes as one of the largest MSK patient data sets and integrates directly into existing EMRs to coordinate triage, care management, billing, and patient communications.
Flagler states it has scaled to thousands of providers in more than 36 states in under three years, reporting $164,000 in average additional annual revenue per provider and 87% of patients reporting improvement in pain, mood, sleep, or mobility.

Bessemer partner Steve Kraus said the firm views Flagler as the only full-stack platform purpose-built for MSK. The company stated the new capital will accelerate its expansion across MSK practices in the U.S.
