Find & validate your idea

I want to start a startup but I don't have an idea. Where do I even begin?

The short answer

Stop hunting for a billion-dollar idea and start collecting problems. The best ideas come from noticing things that annoy you or people around you in a domain you actually know. Become the kind of person good ideas happen to: get deep in a fast-changing field, keep a running list of frustrations, and pick the problem you can't stop thinking about.

Why we picked it Founders often keep validating because they secretly doubt the idea itself, so a structured way to judge the idea is half the readiness question. YC partner Jared Friedman gives an idea quality score across four criteria (how big, founder/market fit, how sure you are the problem is real, and whether you have a genuine insight) plus the bad filters that make founders quietly reject their best ideas. It is the honest bar to check your idea against before you commit to building. A starting framework, not a scorecard to obsess over.

How to Get and Evaluate Startup Ideas

On Y Combinator Startup School by Jared Friedman ~25 min

  • Rate an idea on four criteria and average them, rather than trusting a gut yes or no.
  • Great companies usually started from a good enough idea plus strong execution, not a brilliant one, so waiting for the perfect idea is itself a mistake.
  • Watch for filters (seems hard, boring space, too ambitious, competitors exist) that make you reject strong ideas without realising it.

Why we picked it Before you spend weeks validating, check whether the idea is even worth it. Kevin Hale's filter asks whether the problem is popular, growing, urgent, expensive, mandatory, and frequent. A fast way to drop weak ideas and focus on the ones worth testing.

Why we picked it The opening lecture of the classic Stanford course, and the idea section is exactly what a first-time founder needs. Altman argues the best ideas often sound bad at first and that a mission you care about matters more than a clever pitch. It is a calm, high-signal grounding before you go deeper.

How to Plan an MVP

On Y Combinator (YouTube) by Michael Seibel (YC) ~13 min

  • Talk to users before you build anything.
  • Launch something lean in weeks, not months, the goal is to start the feedback loop.
  • Don't try to solve every problem for every user; ship narrow and ugly.

Why we picked it A short, pointed essay on why the best ideas grow organically out of the founder's own life and knowledge, the essence of founder-market fit. It's the case for building where you already have an unfair edge instead of chasing a market you'd have to learn from scratch.

Organic Startup Ideas

From paulgraham.com by Paul Graham ~5 min read

  • The most fertile ideas are ones you have firsthand because of who you are and what you do.
  • Organic ideas come with built-in founder-market fit, you're already the customer.
  • Forced, non-organic ideas feel plausible but lack the edge to win.

Why we picked it Entering an unfamiliar industry means you cannot see the walls and dead ends that veterans already know. 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. It gives you a concrete goal for your research: build the maze map through history, analogy, and direct experience.

The Idea Maze

From cdixon.org by Chris Dixon short read

  • Value is in the map of the terrain, not the spark of the idea
  • Learn the maze through history, analogy, theory, and direct experience
