How they build

John Rush

Distribution beats building: spend more time on SEO and content than on code and design.
Start SEO on day one — it takes 3–6 months to compound.
Launch many small bets, at most a week each, and cross-link them.
Stay founder-only until traction; skip hiring, outsourcing and paid design before $10k MRR.
Talk like a human on social media and share both wins and failures.

Sergiu Chiriac

Give away a useful resource first, then sell the done-for-you version.
Use your own service to grow your own products.
Share revenue numbers for every product publicly.
