Audience attention is a finite launch resource
Each creator channel — email list, Telegram group, YouTube channel — is a finite distribution resource. Burn it with too many promo hits during a launch and the audience walks. Iteration tests have to be rationed; the channel can't be the MVP variable.
Something that they did right is that they invested a lot in having senior people at the beginning. Yes you spend a bit of money on hiring good people, but then everyone knows what they're doing, everyone is super independent.
Hire senior early — independence beats handholding at 15 people
Paired deliberately over-indexed on senior hires in their first 15 employees rather than stretching budget across more junior staff. The payoff: every hire ships independently without management overhead, which is what actually makes a tiny team feel fast — junior-heavy early teams pay for themselves in coordination cost.
There's a play for whatever you're stuck on.
