Ideas & Opportunity

What does 'validating an idea' actually mean?

A starting point

Validation is gathering real-world evidence that a specific group of people has a painful problem AND will change their behaviour (pay, sign up, switch) for your solution, BEFORE you build the whole thing. It's not asking friends if they like it. It's designing cheap tests that could prove you wrong, and running them.

How to Get and Test Startup Ideas

On YC Startup Library by YC ~30 min

Why we picked it

Bridges the gap between 'I have an idea' and 'I have evidence.' Gives a concrete framework for cheap, fast tests so you stop debating your idea in your head and start putting it in front of reality.

  • An idea is a hypothesis, not a plan, design a test for it.
  • Cheaper, faster tests beat elaborate ones.
  • Look for signal in behaviour, not applause.

The Only Thing That Matters

From pmarchive.com by Marc Andreessen ~15 min read

Why we picked it

The essay that put 'product-market fit' into the startup vocabulary. Read it for the gut-level description of what PMF feels like when it's happening vs when it isn't, the intuition behind the metrics.

  • Market matters most; a great market pulls product out of a startup.
  • You can feel PMF, customers buy as fast as you can ship.
  • Before PMF, do whatever it takes to get there; nothing else counts.

The Lean Startup

From theleanstartup.com by Eric Ries ~330 pages

Why we picked it

The book that gave the world 'MVP', 'build-measure-learn', and 'validated learning'. It reframes a startup as a series of experiments, not a bet, the mental model everything else in this category builds on.

  • Progress = validated learning, not features shipped.
  • Build the minimum that produces a real learning loop.
  • Decide pivot-or-persevere on evidence, on a schedule.
