This is the handbook that launched the most advanced approach to entrepreneurship to date. It gave rise to Eric Ries, Ash Maurya, and Alexander Osterwalder, to name a few. It outlines the four steps of the Customer Development process, focusing first on the customer and the customer's problem rather than the product. It's a classic, and the direct ancestor of The Lean Startup.

"Simply put, a startup should focus on reaching a deep understanding of customers and their problems, their pains, and the jobs they need done, discovering a repeatable roadmap of how they buy, and building a financial model that results in profitability." ~ Steve G. Blank

Key Takeaways

  • Startups don't fail because they lack a product. They fail because they lack customers and a proven financial model.
  • The Customer Development Model isn't a replacement for Product Development, it's a companion to it that tests whether a market actually exists.
  • The four steps are Customer Discovery, Customer Validation, Customer Creation, and Company Building, in that order.
  • The goal of Customer Discovery is simple: turn the founders' hypotheses about the business, market, and customers into facts.
  • Build a roadmap to sales success by selling to a small set of early visionary customers, don't build a sales organization first.
  • Launching a new product is a strategy, not a checklist of marketing tactics to execute.
  • Once a startup finds its model, it has to shift from a team built for learning and discovery into one built for execution, without losing the ability to keep learning.
