Founder Playbook

Before you build, hire, or raise, you need an idea worth pursuing. This playbook is only about that first step: where ideas come from, what makes one promising, and how to pick one. Use ruminator to pressure-test your choice against the competitive landscape.

How to find and judge an idea

1. Generate widely, judge later. List ten problems you have seen firsthand. Paul Graham and Jared Friedman both say the best ideas come organically, from your life, not a blank-page brainstorm.
2. Find your edge. Ask Naval’s question: what do you know that took years to learn and others keep asking you about? Founder-market fit starts here.
3. Question assumptions. Use Elon Musk’s first-principles test: what does everyone assume is fixed or expensive that might not be true? Stripe, Tesla, and SpaceX started here.
4. Evaluate with a framework. Use problem, solution, and insight (Kevin Hale). Is the problem urgent and expensive? Is your solution 10× better? Do you have an unfair advantage?
5. Research before you commit. Map who already serves this space and where incumbents are weak. Use ruminator for competitor context, then compare against your other ideas and pick one or walk away.

Three lenses worth combining

Paul Graham & Jared Friedman: notice problems in your own life. Organic ideas beat forced brainstorming. Elon Musk: question what everyone assumes is true; first-principles thinking finds opportunities incumbents ignore. Steve Jobs: start with the customer experience you want to create, then work backwards. Naval Ravikant: find the overlap between your specific knowledge and a market that pays.

Kevin Hale’s problem, solution, and insight framework is the best single test for whether an idea is worth committing to. Start with the reading list, then the talks, ranked by YouTube engagement.
