A contrarian heuristic against staying lean too long: keep a team small only until you hit conviction, then invest enough people to build the genuinely good version that can win externally. Use it when deciding whether to keep a project scrappy or scale it.
Origin
Stein's hot take against the 'cult of lean.' He argues teams give up too early or underinvest, and that even his Close Friends success was slowed by keeping the team too small too long.
Core principles
- 01The lean-and-scrappy cult is right for internal conviction but wrong for shipping a breakthrough that works for many people.
- 02Two milestones gate scaling: internal conviction (do you believe in it) and external validation (do real users keep coming back).
- 03Friends won't do you favors — 30/60/90 days in they only keep using it if it's genuinely useful, so their retention is honest signal.
How to run it
- 1
Stay small to reach conviction
Run a tiny team (e.g., a PM, designer, engineer, or 5-10 people) to prove the concept and reach internal conviction backed by external validation — put ~20 friends on it and watch whether they still use it after 30/60/90 days.
Pro tip Treat friend retention as truth serum: they won't use it daily just to be nice, so continued use is a real signal.

Recognize the conviction moment
The gate to scale is hitting conviction: you believe in it because there's external validation, even though the shipped version is still broken and wouldn't win externally yet.
Watch out A product friends love in prototype is not a product that wins externally — don't mistake conviction for readiness.

Invest enough to build the winning version
Once conviction lands, staff up enough to make the best (or as good as possible) version and get it out the door. From first principles, size the group to the problem rather than defaulting to two people until escape velocity.
Pro tip For hard technical or big-company efforts, err toward investing more — the common failure is holding teams too small too long, not too large too soon.
Watch out Adding too many people too soon is still a risk; scale after conviction, not before.
In the wild
One reason Close Friends took two-to-three years was that the team was kept so small and scrappy that the loop cycle dragged. Stein notes that at startup speed that pace 'you'd be dead probably.'
→ A big-company team survived the slow pace, but Stein frames the extended timeline as the cost of under-investing after conviction.
Common mistakes
Worshipping lean past conviction
Stein sees teams give up too early or underinvest, letting a promising product 'die on the vine' internally because it never got good enough.
Scaling before conviction
The reverse failure — piling on people before external validation — wastes resources; the gate is the conviction moment.

“people hold on to small teams too long”
“there's two big milestones there's like internal conviction like for yourself do you believe in it”
“they're not going to use a product every single day cuz they're your friend”
