Your AI Doctor Is Coming | Julie Yoo
Julie Yoo, a healthcare investor at Andreessen Horowitz, argues that AI will benefit healthcare more than any other industry because healthcare has historically underinvested in technology, allowing it to leapfrog legacy systems and adopt AI-native solutions directly. She identifies major opportunities in consumer healthcare, AI-native care delivery, robotics, and new payment models, predicting a future where individuals have personalized AI doctors available continuously.
Summary
Julie Yoo shares her 18-year journey in healthcare technology, beginning as a software engineer before transitioning to healthcare during the electronic health records (EHR) digitization era. She founded Kairos, a company addressing the healthcare access paradox—where patients wait months for appointments despite physicians operating below full capacity. After selling Kairos, she joined Andreessen Horowitz as a healthcare investor.
Yoo identifies three major factors driving healthcare's current renaissance: First, consumer expectations have risen due to superior experiences in other industries (Uber, Airbnb, Instacart), creating a gap with stagnant healthcare services. Second, incumbent healthcare systems face mounting cost pressures from expensive labor, talent shortages following COVID, and government cost-containment efforts. Third, AI technology now provides abundant intelligence that can replace scarce medical expertise, making previously impossible solutions feasible.
A critical advantage healthcare holds is its historical underinvestment in technology infrastructure. Unlike other industries that spent decades building middleware software layers, healthcare relied primarily on EHRs and labor. This lower sunk cost bias allows healthcare to leapfrog directly to AI-native workflows rather than ripping out legacy systems. Yoo notes this is the first organic adoption wave in health tech, where physicians voluntarily use AI tools because they genuinely improve work.
On the consumer side, AI chatbots have normalized accessing health information with lower friction than traditional appointments. Companies like Council Health exemplify new possibilities—24/7 asynchronous chat with licensed MDs who can diagnose, prescribe, and refer, combining AI efficiency with clinical credibility. The shift from employer-paid insurance to consumer cost-sharing has made individuals price-sensitive, driving demand for disruptively cheaper AI-enabled services.
Yoo highlights major opportunity areas: consumer health businesses with viable cash-pay models, AI-native and AI-proof companies combining AI intelligence with regulated services, robotics in high-acuity settings, and ambitious companies reimagining healthcare payment systems entirely. She predicts that within a decade, healthcare will feature end-of-one personalized solutions driven by continuous self-generated data, and individuals will have AI doctors in their pockets providing continuous, personalized specialist-level care.
About this episode
a16z General Partner Julie Yoo joins MTS host Sophia Dew to explain why she believes healthcare could benefit more from AI than almost any other industry, and why decades of slow technology adoption may actually give healthcare an advantage in the AI era. Julie traces healthcare’s evolution from paper records and fax machines through electronic health records and telehealth, and explains why AI represents something different: an organic adoption wave driven by tools that doctors and patients actually want to use. Because healthcare never built the same layers of legacy software as other industries, it may now be able to leapfrog directly into agentic AI. They also explore how AI could dramatically lower the cost of care, why consumers are becoming a more important payer, where Julie sees the biggest opportunities for healthcare founders, and a future where everyone has a highly personalized AI doctor in their pocket for life.
Key Insights
- Healthcare's historical underinvestment in technology infrastructure is now an advantage, allowing the industry to adopt AI-native workflows directly without the costly rip-and-replace efforts other industries must undertake with their existing middleware layers.
- This is the first organic adoption wave in healthcare technology where physicians voluntarily adopt AI tools because they genuinely improve clinical work, contrasting sharply with previous unnatural adoption periods that required government incentives or crisis-driven mandates like COVID.
- The shift from employer-covered insurance to consumer cost-sharing through high deductibles fundamentally changed patient behavior, making individuals price-sensitive and enabling new $10-per-month AI-powered services that deliver dramatically better value than traditional healthcare.
- AI-native healthcare companies achieve sustainable competitive advantages by combining AI intelligence with regulated clinical services (diagnosis, prescription, referral), creating surface area and cost structures impossible through historical means while maintaining clinical credibility.
- Healthcare's sparse data problem—patients see traditional doctors only about once annually—means current datasets are insufficient to train truly comprehensive medical AI, creating opportunity for companies generating continuous end-of-one health data that will enable next-generation models.

Healthcare is one of the most expensive industries in the world, yet time and medical expertise remain scarce. Julie Yu thinks AI could change that. The A16Z General Partner joins Sophia Du on MTS to explain why healthcare may benefit more from AI than almost any other industry, and why its slow adoption of technology could now be an advantage, allowing it to leapfrog legacy software and move directly to AI-native workflows. Julie also shares where she sees the biggest opportunities for founders, from consumer healthcare and AI-native care delivery, to robotics and new payment models, and why the future could include an AI doctor in your pocket for life. Julie, welcome to MTS. Thanks so much for having me.…

Aaron Levie on Why Open AI Wins
Aaron Levie, CEO of Box, discusses why open-weight AI models benefit the entire AI ecosystem rather than threatening frontier labs, argues that the economic value in AI accrues to inference infrastructure rather than model weights, and explains why model routing will become the default enterprise AI strategy.
Fei Fei Li: The Race to Build World Models For AI
World Labs launched Atlas, a new world model built on next-view prediction that unifies 3D reconstruction and generation. The model can create spatially-grounded video frames from sparse input images (as few as three), reducing the data requirements for 3D scene capture by 50-100x, with applications ranging from creative content to robotics simulation.
The $100B Niches Hiding Inside Payments
Max Levchin and Alex Rampell discuss 25+ years of payments innovation, tracing PayPal's origins through their journey building Affirm. They explore how the credit card remains the best payment interface ever created, why there are no niches smaller than $100B in payments, and how AI may finally be ready to reinvent the payment experience itself.
Inside Moderna’s Personalized Cancer Vaccine
Moderna and Merck announced positive Phase 3 results for an individualized mRNA cancer vaccine (Intesmiran) for melanoma, achieving 80% disease-free survival at five years compared to 60% with Keytruda alone. The breakthrough combines mRNA technology with personalization, sequencing each patient's tumor to identify mutations and create a patient-specific vaccine that teaches the immune system to recognize cancer cells.
Daniel Litt: The Mathematician's Guide to AI
Daniel Litt, a mathematician at University of Toronto, discusses AI's evolving capabilities in mathematics, distinguishing between what models can do well (applying known techniques, solving specific problems) versus where they fall short (developing intuition, building new theories, asking fundamental questions). He emphasizes that while AI results are impressive, the mathematics community must adapt its incentive structures to preserve human understanding and maintain cognitive diversity in mathematical research.
