Backed by FPV Ventures and McKesson Ventures, Oath is scaling a national network of high-tech surgery centers, cutting costs up to 80% while elevating quality and patient experience.

SAN FRANCISCO–(BUSINESS WIRE)–Oath Surgical today announced an oversubscribed $24M Series A led by FPV Ventures with participation from McKesson Ventures and existing investors OSE, Black Opal Ventures, Tau Ventures, and Rogue VC, bringing total funding to $35M. The company will use the capital to expand into new specialties like oncology, scale its national value-based network of surgeon-owned, tech-powered surgery centers, and advance OathOS—the first and only AI platform built to replace the industry’s patchwork of systems.

The Healthcare Cost Crisis

Surgery is the single largest cost in U.S. healthcare, driving between $500 billion and $1 trillion annually. By 2026, Medicare will allow over 51 million procedures to move outpatient, creating urgent demand for high-tech centers that can deliver complex care safely and at scale.

“Surgery is at a turning point,” said Oliver Keown, MD, Oath Surgical Founder and CEO. “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.”

OathOS: A System Built for the AI Era

Surgeons have long been forced to juggle scheduling apps, billing portals, and clunky reporting systems. OathOS replaces all of it with a single, superintelligent AI platform that embeds automation across the entire surgical journey, from referral to recovery, making every procedure faster, safer, and more consistent.

For surgeons, OathOS delivers the first true AI-powered operating room—streamlining workflows, eliminating bottlenecks, and real-time data. For patients, it means faster care, same-day recovery, and a smoother experience. For payors, it means a consistent, lower-cost system with transparent outcomes.

“At FPV, we back mission-driven founders who are building the systems that will shape the future, often long before others can see it,” said Pegah Ebrahimi, General Partner at FPV Ventures. “When we met Oliver and his team, we saw the rare combination of vision, founder-market fit, and conviction it takes to rethink surgery from first principles and rebuild it for the future.”

A National Network of Surgeons

Unlike traditional outpatient centers that operate in silos, Oath is building a unified national platform: surgeon-owned facilities and quality providers connected by the same high-tech backbone. This creates alignment across stakeholders and enables payors to confidently channel complex procedures to lower-cost, high-quality settings, while Oath surgeons maintain autonomy and patients benefit from consistency and a premium experience.

In just 12 months, Oath has grown to more than 150 surgeon partners and proven its model on the West Coast. Early results show the power of its system:

• Up to 80% cost savings compared to hospital-based procedures, as much as $100,000
• <0.25% complication rate across complex surgeries
• 98.5% patient satisfaction
• Same-day discharge, with patients recovering in days, not weeks or months

Positioned for Rapid Expansion

With Series A funding, Oath is preparing for national growth. By the end of 2025, it will expand its network of high-tech, multispecialty centers into new markets, offering programs across urology, gynecology, general surgery, neurology spine, ENT, orthopedics, pain, and more. The company is also making a bold push into surgical oncology, a multi-billion-dollar segment projected to grow 15% annually over the next decade.

“Delivering high quality, complex oncology and specialty care in the community requires true innovation for patients, their families, providers and payors to achieve the best possible outcomes,” said Carrie Williams, Partner at McKesson Ventures. “We’re proud to support Oath on this path toward an optimized care experience for all these key stakeholders.”
