Find & validate your idea

How do I turn a vague hunch that something is broken into a sharp, testable idea?

The short answer

A hunch becomes an idea when you can name the person, the moment the pain hits, and what they do today to cope. Follow the workaround: every ugly spreadsheet, WhatsApp forward, or manual hack is a signpost to a problem someone already pays to avoid. Write your idea as a hypothesis you could disprove in a week, not a mission statement.

Why we picked it A YC partner turns 'talk to users' into a repeatable 5-question interview script you can use this afternoon. It's The Mom Test compressed into a lecture, perfect if you want the method fast before reading the book.

How to Talk to Users

On YC Startup Library by Eric Migicovsky (YC / founder of Pebble) ~25 min

  • Don't pitch your idea, you'll bias every answer.
  • Anchor on the last time they hit the problem, and what they did about it.
  • If they've done nothing to solve it, the problem may not be painful enough.

Why we picked it When you are new to a space, your instinct is to explain your idea and hope people nod, which teaches you nothing. This YC talk is a concrete guide to running discovery interviews the right way: extract data from the person instead of pitching, and use a small set of questions that work in any industry, including one you are still learning. It pairs well with The Mom Test as the applied version you can watch before your next call.

How to Talk to Users

On Y Combinator (Startup School) by Eric Migicovsky ~25 min

  • The interview is to extract data, not to sell: stop talking about your idea and let them talk about their problem.
  • Skip hypothetical questions (would you use this) and ask what they have actually done to solve the problem today.
  • A handful of questions works across any industry, so you can start interviewing before you are an expert in the space.

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.

Ideas for Startups

  • There's essentially no market for startup ideas, which tells you what they're worth on their own.
  • Most startups end up nothing like the initial idea; the value emerges through execution and iteration.
  • Treat ideas as questions to explore, not blueprints to guard.
  • Develop ideas openly with co-founders and friends rather than locking them away.

Why we picked it When 20 interviews each surface a slightly different problem, the fix is not more interviews, it is a structure to sort them. Teresa Torres's opportunity solution tree gives you exactly that: a way to map every pain point you heard against one desired outcome, so real, recurring opportunities separate themselves from one-off noise. This guide is the clearest free explanation of the method, and it points to the full book if you want to go deeper.

Continuous Discovery Habits: Discover Products that Create Customer Value and Business Value

From Product Talk by Teresa Torres ~10 min read (companion to a full book)

  • Group each interview finding as an opportunity (a customer need, pain, or desire) and place it under a single desired outcome, so patterns become visible instead of a flat list of quotes.
  • A problem that keeps recurring across interviews earns a spot on the tree, a one-off mention does not, which is a concrete rule for pattern versus noise.
  • The tree is meant to keep changing as you keep talking to customers, so treat your 20 interviews as a starting point, not a finished map.

Why we picked it The cleanest distillation of the one framework that turns a customer chat into a relationship instead of a survey. The three rules (talk about their life not your idea, ask about the past not hypotheticals, and chase real commitments of time, reputation, or money) are exactly how you get an early customer to tell you what nearly stopped them from buying and who else you should talk to. Rekhi is a product leader, so the examples are operator-grade, not book-report fluff.

From Sachin Rekhi's Blog by Sachin Rekhi 10 min read

  • Never pitch your idea in the conversation; ask how they handle the problem today and what it costs them, so praise can't lie to you.
  • The strongest signal is a commitment that costs them something: a trial, an intro to a colleague, or a pre-order.
  • 'Would you buy this?' teaches you nothing; 'walk me through the last time you dealt with this' surfaces the real story and the referral.

Why we picked it Shah argues that to make people switch from what they already use, you need a large jump in perceived efficiency, not a marginal one. In a crowded market that is the bar for your wedge: the incumbent may be good enough for most, so your narrow segment has to feel a dramatic gain. Read it to sanity check whether your improvement is big enough to change behavior.

Why we picked it The Test Card is a one-page worksheet that forces a vague market-size belief into four fields: what we believe, how we will test it, what we will measure, and what result would prove us right. Fill one out for each cofounder's version of the market and the disagreement stops being a debate and becomes two experiments with clear pass or fail bars. It is free, widely used, and takes minutes to complete, so there is no excuse to keep arguing in the abstract.

Test Card

From Strategyzer by Strategyzer (Alexander Osterwalder) one-page worksheet

  • It converts a differing assumption into a hypothesis plus a concrete metric and a success threshold, so you both agree in advance on what would change your mind.
  • Writing each cofounder's belief on a separate card surfaces exactly where the two of you actually diverge.
  • Pair it with the companion Learning Card to record what the test showed, so the decision is documented, not relitigated later.
