Early days, but so far General Medicine has the highest NPS of anything we’ve built (pillpack, amazon pharmacy, amazon clinic) and frankly, any consumer product I’ve seen. And PillPack was always kicking around 80.
I’ve never understood the trope “missionaries not mercenaries”, especially coming from massive for-profit corporations. Can someone explain this to me?

Ladies and gentlemen, I've officially posted my way to the top: I'm joining @X as Head of Product. 𝕏 is the most important social network in the world. It's where internet culture originates and where the world's most influential people convene. Finding my community and…
Maybe we’re thinking about this healthcare startup capitalization thing all wrong

What are the best examples / implementations of adversarial consumer AI? Eg designed to break the AI.
