SAN FRANCISCO– Oath Surgical announced it has raised $24 million in an oversubscribed Series A round led by FPV Ventures, with participation from McKesson Ventures and existing investors OSE, Black Opal Ventures, Tau Ventures, and Rogue VC. The latest funding brings Oath’s total capital raised to $35 million and will fuel the company’s expansion into new surgical specialties, including oncology, while scaling its national network of surgeon-owned, AI-driven surgery centers.
The company is also advancing OathOS — the first and only artificial intelligence platform designed to replace the healthcare industry’s fragmented systems with a unified, intelligent operating backbone. By integrating automation and real-time data across the surgical process, OathOS aims to transform how surgeons, patients, and payors experience and manage surgical care.
“Surgery is at a turning point,” said Oliver Keown, M.D., Founder and CEO of Oath Surgical. “The shift of complex care out of hospitals is inevitable, but it won’t happen by chance. It will take a new kind of system — high-tech, surgeon-led, and aligned across patients, providers, and payors. That’s what we’re building at Oath.”
Surgery is the single largest expense in U.S. healthcare, accounting for between $500 billion and $1 trillion annually. With Medicare expected to allow more than 51 million procedures to move to outpatient settings by 2026, there is growing demand for high-tech centers that can deliver complex care safely and affordably at scale.
OathOS replaces the industry’s patchwork of disconnected tools — including scheduling, billing, and reporting systems — with a single AI platform that streamlines workflows from referral through recovery. For surgeons, it creates an intelligent, automated operating environment that reduces bottlenecks and improves precision. For patients, it enables faster care, same-day recovery, and smoother experiences. For payors, it delivers consistency, transparency, and dramatically lower costs.
“At FPV, we back mission-driven founders building the systems that shape the future,” said Pegah Ebrahimi, General Partner at FPV Ventures. “When we met Oliver and his team, we saw the rare combination of vision, expertise, and conviction needed to rethink surgery from first principles and rebuild it for the modern era.”
Unlike traditional outpatient surgery centers, Oath is creating a unified, surgeon-owned national network connected by a shared AI infrastructure. This model aligns surgeons, payors, and patients through consistent quality, data transparency, and efficiency. Over the past year, Oath has grown to more than 150 surgeon partners, demonstrating early success on the West Coast. Initial results show up to 80 percent cost savings compared to hospital-based surgeries — reducing costs by as much as $100,000 per procedure — with less than 0.25 percent complication rates, 98.5 percent patient satisfaction, and same-day discharges.
With its new funding, Oath plans to expand its high-tech, multispecialty centers nationwide by the end of 2025, introducing programs across urology, gynecology, orthopedics, ENT, neurology spine, pain management, and general surgery. The company is also entering the fast-growing field of surgical oncology, a segment expected to expand 15 percent annually over the next decade.
“Delivering high-quality, complex oncology and specialty care in community settings requires true innovation for patients, their families, providers, and payors,” said Carrie Williams, Partner at McKesson Ventures. “We’re proud to support Oath on its mission to redefine surgical care and create a modern, optimized experience for all stakeholders.”
By combining surgeon ownership, AI-powered operations, and a scalable national network, Oath Surgical aims to reshape how surgical care is delivered — cutting costs dramatically while improving quality, consistency, and patient outcomes across the United States.
