If you're serious about launching a startup, there’s one question you must answer before you invest your time, money, reputation, and years of your life:
 
Is it really a great idea?
 
Most entrepreneurship books focus on execution. This one focuses on evaluation.
 
Because every failed startup once sounded exciting. Every founder once believed. Every investor pitch once looked promising. But passion, optimism, and hype are not evidence.
 
In this substantially expanded and refined Second Edition, entrepreneur, investor, and SMU entrepreneurship professor Yoram Solomon presents a brutally honest framework for evaluating ideas before you build them, fund them, or bet your future on them.
 
Built around a practical Three-Loop Evaluation Process, the book walks you through six essential tests every idea must survive:
The Customer Test — Are you solving the right problem for the right customer?
The Pain or Gain Test — Does the problem truly matter—or does the gain genuinely motivate action?
The Value Test — Is your solution meaningfully better than the customer’s current alternative?
The Validation Test — Can you prove customers will actually act, buy, or change behavior?
The Defensibility Test — Can competitors easily copy your advantage?
The Business Model Test — Can the business actually survive and scale profitably?
 
This edition significantly expands the original framework with:
deeper customer and behavioral analysis
hidden pain and gain discovery
stronger validation and testing methods
a redesigned value evaluation model
modern defensibility analysis, including AI-related realities
more real-world examples, tools, and decision frameworks
 
Inside, you’ll find:
practical evaluation tools and worksheets
investor-style thinking and startup filters
real-world examples and failure patterns
frameworks used in entrepreneurship classrooms and startup evaluations
brutally honest guidance for killing weak ideas before they consume your life
 
This is not a motivational startup book.
 
It’s a decision-making tool for entrepreneurs, students, innovators, investors, and leaders who care more about truth than excitement.
 
Don’t fall in love with your idea.
 
Fall in love with finding out whether it deserves to exist.
