Nicholas Bernhardt-Lanier

Hi, I'm Nicholas. I work at the intersection of health and technology.

Building

Proto Intelligence — Co-Founder & CEO. LLM-native clinical OS, building harness to automate 80% of care, with a team from Tempus AI, Stanford Medicine, and One Medical.
Humanaut Health — VP Product, employee #1. Software to power 50-state longevity clinics with 700+ biomarkers, peptides, and regenerative therapies.
McKinsey — Early GenAI team. Enterprise and healthcare buildouts for Fortune 100 clients.
Doc.ai — PM. AI models on real-world medical data to accelerate breakthrough research.

A handful of threads I keep pulling on. Notes here are deliberately rough — closer to a working file than an essay.

Techno-feudalism The AI platforms we depend on won't behave like markets, they'll behave like fiefs. Who collects rent (compute), who owes loyalty (data), and what happens when the people fight back.
Biological inequality The next generation of therapeutics, peptides, gene therapies, AI-personalized medicine, will reach the wealthy first by an order of magnitude. The question is whether the gap closes in years, or whether we stratify into a permanently tiered biology.
The psychosomatic effects of chatbots A generation is about to grow up doing daily emotional work with language models. That will rewrite how people think, feel, and cope, long before we have the studies to explain and solve it.
Enterprise re-orgs around AI The largest governance transformation since the assembly line, with no playbook. The orgs that figure out which decisions belong to humans and which to models will compound at an exponential rate.
