Find & validate your idea

How do I generate a steady flow of idea candidates instead of waiting for one big flash?

The short answer

Good ideas come from a system, not a lightning bolt. Keep a running list of every annoyance, workaround, and "why is this still so bad" moment you notice, and review it weekly for patterns. The founders who seem to have great instincts are usually just the ones who wrote down a hundred small observations and pattern-matched across them.

Why we picked it A YC partner turns 'how do I get an idea' into a concrete checklist you can run today, plus the traps (tarpit ideas) that sink beginners. It's the practical companion to Paul Graham's essay, with a repeatable framework for judging an idea's strength.

How to Get and Evaluate Startup Ideas

On YC Startup Library by Jared Friedman (Y Combinator) ~50 min

  • Evaluate ideas on the problem: how many people have it, how often, and how badly.
  • Watch out for 'tarpit ideas' that feel exciting but have quietly killed hundreds of startups.
  • The best sources are your own expertise, things you personally wish existed, and noticing recent changes.

Why we picked it A short, plain-spoken YC talk where Seibel says it outright: be in love with your problem and your customer, and treat the product as something that can change. He walks through grading a problem instead of grading an idea, and picking a handful of real early users to check whether your solution actually lands. It is the fastest way to reset from solution-first thinking without reading a whole book.

How to Get and Test Startup Ideas

On Y Combinator by Michael Seibel ~15 min

  • Grade the problem, not the idea, because a problem is easier to judge honestly than a solution you are already attached to.
  • Stay in love with the problem and the customer and keep the product flexible, since the first version is rarely the one that works.
  • Test with a small set of hand-picked users who truly have the problem, rather than chasing early adoption numbers.

Why we picked it Using Airbnb, Stripe, and Coinbase, the pair show that the strongest ideas came from founders living inside a real problem, not from a clever brainstorm. They separate organic ideas (born from a pain you felt) from manufactured ones that usually fizzle. Watch it to recognize whether your idea is rooted in a real problem or wishful thinking.

Where Do Great Startup Ideas Come From?

  • Organic ideas come from a problem you personally lived through
  • Manufactured 'we should build an app for X' ideas usually stall

Dixon explains that a good founder holds a map of who tried this before, what happened, and why, and that this map is what real domain knowledge looks like.
