Distribution and SEO matter more than features.
Track every traffic source; one listicle placement can make your best month.
Optimize content so AI search engines cite you, not just Google.
Run many small products and cross-promote them.

Jakob Greenfeld

Act without asking for permission — most of his wins came from just shipping.
Launch many small, cheap experiments and let the market tell you which to keep.
Mine data (marketplaces, newsletters, filings) to find business opportunities others overlook.
B2B services and distribution often beat building yet another SaaS product.
The bar is low: most competitors barely try, so consistent effort stands out.
