the biggest scam in functional medicine is cash pay practitioners who financially benefit from you continuing to visit.
if someone profits from you coming back, where is the incentive to be honest about what you actually need?
friend of mine went to an acupuncturist and was told "you need to come 3x per week if you want to see any benefits". that's $120 per session or $1,500/month.
instead, they spent 5 minutes on chatgpt and turns out 1x every two weeks is the standard for their condition. the practitioner recommended 6x the necessary frequency.
this is where AI actually matters in health. giving patients the ability to question what they're being told.
if someone profits from you staying on their schedule, question everything.
clinicians are just people. the incentive is not always your health.

If you bought a Whoop, I feel sorry for you.
Google’s Fitbit Air just made it look silly
- $100 one time payment vs Whoop’s $199–$359/year forever
- Free tier actually works HR, sleep, SpO2, HRV, recovery, no paywall
- Optional $10/mo for Gemini Health Coach (vs Whoop where the sub is mandatory)
- Gemini analyzes meal photos, not just biometrics. Whoop can’t touch that
- Conversational health AI ask questions like why was I tired Tuesday?and get a real answer
- Open data platform Apple Watch, Garmin, third-party data all flow into Google Health
- 7-day battery, 5-min quick charge = full day
-Whoop just got a $10B valuation… and Google undercut them by 50% on day one

a lot of horizontal companies are very attracted to healthcare because it's a huge market and a lot of tedious work - but most struggle because they don't understand how the industry actually works
excited to announce healthcare 101 is back 7/13 - 7/24 (virtually)! I will teach you all of the different weird incentives and players in the space, which took me 10 years to figure out
You will be able to answer questions like
- "why don't practices pay for anything"
- "what does health insurance care about"
- "why don't people get paid for making patients healthy"
- "why are there so many acronyms for everything jesus christ"
You can sign up in the comments, you will be enlightened

@maxmarchione Now we just need regulatory to loosen so more builders can enter

We are living through the disruption of healthcare in real time.
Every industry gets disrupted the same way.
It starts when only the rich can afford it and only experts can use/deliver it (e.g. telephones, air travel, computers)
Then technology changes everything:
- It lowers cost
- Improves and standardizes quality
- Makes it accessible to everyone
A few examples of this throughout history:
- NY to London call used to cost $300 for 3 min in 1930, and is now free.
- Cross-country flight cost $4,400 in the 1940s, today it's $120.
- A 1980 computer used to cost $10M, now you get your iPhone for $1K, which is 1000x more powerful.
Healthcare is now on the same trajectory.
- The cost of sequencing a human genome dropped from $100M to less than $100 in about 25 years
- Full-body MRI used to be hospital-only, now you can get it for $500.
- Blood panel went from $500 to $30.
- CGM was prescription-only, now $70/month.
The gates always fall.
