Nate Gross on AI market dynamics
From OpenAI's VP of Health Nate Gross · · The Heart of Healthcare | A Digital Health Podcast
“It's probably not going to be one company capturing the whole category. If one company captures 20% of GDP as you see in every deck that pitches you, then good for them. That's that's a lot to bite off. It's too large. It's it's too fragmented and it's it's really too workflow specific. So I I think it's it's going to be more like who helps the systems win.”

About Nate Gross
Nate Gross, co-founder and chief strategy officer at Doximity, appeared on the Heart of Healthcare podcast in April 2026, discussing his role as Vice President of Health at OpenAI. Gross stated that 40 million people use ChatGPT for health-related questions daily, and that the company views this as a responsibility to build healthcare apps. He described the development of HealthBench, a tool created with hundreds of physicians using thousands of clinical scenarios to train models on when to ask for context or express uncertainty. Gross addressed the use of AI in mental health, characterizing it as "a story of support, not substitution" and said the goal is for ChatGPT to respond "supportively, safely." He noted that nearly a quarter of American adults have used AI for mental health concerns, according to a Gallup poll. On the topic of AI prescribing, Gross suggested that certain areas like medication refills may be solved by AI, while other areas like chemotherapy remain "a very human experience." He also commented on healthcare incentives, stating that technology "doesn't fix who pays" or "who's accountable," and called for continued national conversations around incentive alignment.
