Nail the Customer Development Manifesto to the Wall

Steve Blank Free Intermediate

Blank invented customer development, and this manifesto boils it into a short set of rules, starting with the idea that there are no facts inside your building so get outside. It is the origin of the discipline that says a startup is a search for a business model you must test, not execute. Read it for the founding principles in one page.

  • There are no facts inside the building, so get out and talk to customers
  • A startup searches for a business model, it does not just execute a plan
  • Your assumptions are hypotheses until customer evidence confirms them

It answers 4 questions

  1. What does 'validating an idea' actually mean?
  2. How do I talk to customers without getting false positives?
  3. How is validating a B2B idea different from validating a consumer app?
  4. How do I do user research when I'm building something nobody has seen before and can't describe what they want?
