03Lessons
What you can take from it
- 01
Your past work can be your edge: Bolt reused 7 years of tech already built.
- 02
A demo that speaks for itself can be your whole launch: one tweet was enough.
- 03
Being close to failure doesn't mean you're done: the right pivot can come late.
“In the first 2 months, we went from 0 to 20 million of ARR.”
Figures come from public sources (press, the founders’ own posts) and are sometimes self-reported.
