Abridge Names San Oo Chief Technology Officer to Scale Its Healthcare AI Intelligence Platform

Abridge, the leading enterprise AI platform for healthcare, has named San Oo its new Chief Technology Officer. Oo joins Abridge after a distinguished career helping build Slack and Notion into platforms used by hundreds of millions of people worldwide — and will now apply that experience to one of the most consequential domains in technology: healthcare.

The appointment comes at a pivotal moment for Abridge, which is live in more than 270 of the largest health systems in the United States — including Duke Health, Johns Hopkins Medicine, Sutter Health, and Yale New Haven Health. The platform is projected to support more than 100 million patient conversations in 2026, as the company rapidly expands its capabilities across the broader healthcare ecosystem while staying anchored to the needs of clinicians.

Oo succeeds Zachary Lipton, the prior CTO, who transitioned into a science advisory role with the company after receiving tenure at Carnegie Mellon University. He will join Abridge leadership at their first-ever keynote on June 11 in New York City, where the company will share more about broader platform innovation.

A Career Built on Scale

San Oo brings a career defined by building engineering organizations during critical inflection points. Most recently, he served as Senior Vice President of Engineering at Notion, where he set engineering goals and directions with a strong focus on reliability, developer velocity, and agentic engineering. Before that, he helped build the engineering organization at Slack during the hypergrowth years that defined modern workplace collaboration.

Earlier in his career, Oo served as CTO at ShopBack, a unicorn in the Asia-Pacific region, and was a founding member of two companies later acquired by major technology players: Mumbo Inc., acquired by LinkedIn in 2012, and Astro Technology, acquired by Slack in 2018. He began his career at Yahoo.

This breadth of experience — from startup founding to scaling platforms with hundreds of millions of users — is precisely what Abridge is counting on as it transitions from a leading AI documentation tool into a foundational AI operating layer for healthcare delivery systems.

"The platforms San helped build altered the texture of work with thoughtful technology and exceptional craft that facilitate human connection. Healthcare is the next industry that needs that kind of care and platform-level rethink, and San is the rare engineering leader who's done it multiple times."

— Dr. Shiv Rao, CEO & Founder, Abridge

The Opportunity in Healthcare AI

Abridge's thesis is straightforward but ambitious: the conversation between a clinician and a patient is the most important moment in healthcare, and AI can fundamentally transform how that intelligence flows across an entire care system. The platform captures and structures clinical conversations in real time, surfacing insights that reduce documentation burden, improve care coordination, and help clinicians focus on patients rather than paperwork.

For Oo, the draw to healthcare is personal and professional. He sees a direct parallel between the transformation he witnessed at Slack and Notion — where thoughtful technology changed how people collaborate — and the transformation now underway in clinical environments. The challenges are harder: systems are more fragmented, stakes are higher, and the margin for error is narrower. That is precisely what makes the opportunity compelling.

"I've spent my career building products and platforms that people love to use that are secure and reliable. Now I want to do the same for healthcare, where the stakes are even higher. Abridge already sits at the center of the most important moment in healthcare, the conversation between a clinician and a patient. The opportunity now is to extend that intelligence across the entire system."

What Oo Brings to Abridge

Oo's mandate at Abridge reflects where the company is headed: beyond ambient documentation and toward a full-stack clinical intelligence platform. The priorities he refined at Notion — reliability, developer velocity, and agentic engineering — map directly onto the challenges Abridge faces as it scales to hundreds of health systems and hundreds of millions of patient interactions.

Abridge's Track Record of Recognition

Abridge has earned a string of prominent industry accolades that reflect its momentum in the healthcare AI market. The company was awarded Best in KLAS for Ambient AI in both 2025 and 2026, a distinction that reflects customer satisfaction and clinical outcomes at scale. It has also been recognized by TIME as one of the Best Inventions of 2024 and 2025, named to CNBC Disruptor 2025, and listed among Fast Company's Most Innovative Companies of both 2025 and 2026.

These accolades, combined with the scale of its health system partnerships and the projected volume of patient conversations, position Abridge not merely as a documentation vendor but as a foundational AI operating layer for large-scale healthcare delivery. Oo's appointment signals that the company is investing in the engineering leadership it needs to sustain that trajectory.

San Oo's appointment marks a deliberate signal from Abridge about its ambitions. The company is not positioning itself as a point solution for clinical documentation — it is building toward a foundational AI platform that can reshape how intelligence flows across the entire healthcare system. With a CTO who has scaled platforms through hypergrowth at two of the defining enterprise software companies of the past decade, Abridge is equipping itself for that next phase of expansion.
