Leadership Comments

“MSK is where the healthcare system's dysfunction is most visible,” said Albert Katz, CEO of Flagler Health and former MSK clinic operator. “Shrinking reimbursements, administrative overload, inefficient triage - I watched it destroy clinician morale and clinic margins at the same time. This isn't a workflow problem. It's structural. The cost of running these clinics keeps climbing, and that cost is a major reason American healthcare is so expensive. It's unsustainable, and we're the only platform built to fix it at the root.”

“Every doctor has wanted a tool like this and assumed it couldn't exist - something that genuinely improves patient outcomes without adding to their workload,” said Dr. Leon Anijar, co-founder and Chief Medical Officer of Flagler. “With AI, that's no longer wishful thinking. Flagler makes the patient experience and the physician experience work together instead of against each other.”

“What drew us to Flagler was rare: a founding team with exactly the right combination of healthcare operations experience, clinical authority, and AI expertise, all applied to one of the largest and most underserved markets in healthcare,” said Steve Kraus, partner at Bessemer Venture Partners. “The traction and ROI they've built in under three years reflects that. Flagler is the only full-stack platform purpose-built for MSK, and we believe it's on its way to becoming the AI-native operating system for every clinic in this space.”
