Jason Cohen
Two unicorns, one bootstrapped and one funded. The rare voice who's done both.
Best for: Operators who want a thinking toolkit, not just war stories.
Jason has built four companies and produced two unicorns: Smart Bear (bootstrapped to millions in profit, sold in 2007; later resold for ~$2B) and WP Engine (bootstrapped for two years, then raised $300M+ to fuel hyper-growth to a unicorn with 1,200 employees). That combination, built one bootstrapped and built one funded, is rare. He knows when each path is right and how to make the switch.
His writing is the most useful "operator's handbook" out there for early-stage founders: pricing, positioning, finding repeatable customer acquisition, and getting to true product/market fit. The one I quote most often is his use of Fermi estimation for decisions that look like they don't have a quantitative component. It brings real rigor to calls most founders make on gut feel alone.
Reach for him when you're stuck on a decision and need a framework for breaking it into knowable parts.
- Product/Market Fit (PMF): Experience & Data - The definitive piece on what PMF actually is and how to know you have it. Read this before you tell an investor you've found it.
- The roadmap to Product/Market Fit (PMF)… maybe - A practical sequence for working toward PMF deliberately, not by accident.
- Fermi ROI: Fixing the ROI rubric - His framework for using Fermi estimation to make decisions that look like they don't have a quantitative component.
