What you'll learn

Key ideas in Entrepreneurship: The Early-Stage Playbook

  • Hypothetical questions invite polite guesses that almost always overstate future usage
  • Grounding interviews in specific past events reveals actual user friction and real habits
  • Asking how someone solved a problem recently uncovers current tools and actual time spent
  • Pitching an idea early biases subjects toward giving polite praise rather than honest critique
  • The Mom Test requires keeping focus on the user's life and workflow instead of your product
  • Valid problem discovery happens when customers talk about their challenges without knowing your solution
  • Free signups and compliments cost the customer nothing and generate false-positive demand
  • Securing upfront capital or formal purchase terms tests true commercial willingness to pay
  • Validating price resistance before building prevents building products customers admire but won't fund
  • Smoke tests require customers to stake cash, reputational capital, or legal intent
  • Surveys measure declared opinions which routinely contradict actual purchasing behavior
  • Urgent problems force customers to duct-tape manual hacks, tools, or staff together today
  • Unprompted complaints indicate real frustration, but lack proof of budget allocation
  • Passive agreement during an interview indicates the issue is low-priority or negligible
  • Concierge tests openly provide hands-on manual help to study value hypotheses directly
  • Wizard of Oz prototypes simulate automation via hidden manual backend work
