Oath Surgical announced an oversubscribed $24 million Series A financing round, 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 $35 million.

The company said it plans to 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 artificial intelligence (AI) platform built to replace the industry’s patchwork of systems.

Surgeons have long had to juggle scheduling apps, billing portals, and reporting systems. OathOS replaces all these with a single, superintelligence AI platform that embeds automation across the whole surgical journey.

According to the company, OathOS provides the first true AI-powered operating room—streamlining workflows, removing bottlenecks, and real-time data. This means faster care, same-day recovery, and a smoother experience for patients. For payors, it means a consistent, lower-cost system with transparent outcomes.

Oath is building a unified national platform of surgeon-owned facilities and quality providers connected by the same high-tech system. This creates alignment for stakeholders and lets payors confidently channel complex procedures to lower-cost, high-quality settings. Oath surgeons keep autonomy and patients benefit from consistency, as well.

In a year, Oath has grown to over 150 surgeon partners and proven its model on the West Coast. Early results show up to 80% cost savings compared to hospital-based procedures, as much as $100,000. An under 0.25% complication rate was shown across complex surgeries, with 98.5% patient satisfaction and same-day discharge with patients recovering in days.

Be the end of the year, the company plans to expand its network into new markets, providing programs in urology, gynecology, general surgery, neurology spine, ENT, orthopedics, pain, and more. The company is also making a push into surgical oncology.

“Surgery is at a turning point,” said Oliver Keown, MD, Oath Surgical’s 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.”
