Ideas & Opportunity

How do I validate an idea in an industry I have no background in?

A starting point

Being an outsider is fine, staying an outsider is fatal. Your first job is to buy insider knowledge with time: spend a few weeks doing nothing but talking to people who live the problem, sit in on their work, and learn the vocabulary well enough that no one can tell you're new. The trap is falling in love with an outsider's clever solution to a problem you don't actually understand yet, so validate the problem far harder than the idea.

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
  • 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 The single best thing ever written on customer conversations. It teaches you to ask about the customer's life and past behaviour, not your idea, so you can't be lied to. If a founder reads one thing before talking to a single customer, it's this.

The Mom Test

From momtestbook.com by Rob Fitzpatrick ~130 pages

  • Talk about their life, not your idea.
  • Ask about specifics in the past, not opinions about the future.
  • 'That's so cool, I'd totally buy it' is a compliment, not data, dig for commitment and evidence.

Why we picked it A VC and HBS lecturer takes on the belief that you must be a domain insider to win, and he is honest about both sides: the outsider's fresh perspective is real, but so is the knowledge gap you have to close. He lays out how founders like the ones behind Shippo and Plastiq did it, through rigorous self-education, hiring genuine domain experts, and staying close to customers. Use it as a starting point to decide which gaps you close by learning and which you close by partnering.

The Outsiders: Defying the Myth of Founder-Market Fit

From Jeff Bussgang (Flybridge, Harvard Business School) by Jeff Bussgang ~10 min read

  • Being an outsider can be an edge, but only if you study the industry with the seriousness of a graduate student and keep talking to real customers.
  • Closing the knowledge gap often means hiring or partnering with a domain expert who shares your values, not pretending you already know.
  • Domain expertise is one input, not a gate: passion, persistence, and the ability to attract people matter at least as much.
