a16z just asked 500 Americans what they do for their health. The answers describe a market that runs on the consumer's own money.

  • 71% would use one app for their records, labs, wearable data and care, and 49% would pay for it

  • 70% filter their water, and 62% would pay more for anything labeled non-toxic

  • 54% wear a health tracker, and 83% of them check it every day

What changed? For decades, taking care of your health meant seeing a doctor once a year and buying what insurance covered. Then COVID showed people that a yearly physical doesn't mean you're healthy, and ChatGPT let anyone ask a medical question and get an answer in plain English.

→ a16z's bet is that the next great health companies will help people act on what they already want to know.

📚 In this newsletter, we break down the six markets in the report, with Andrew Huberman, OpenAI's head of health AI and a16z's own partners explaining each one on video!
