The Modern Sales Reality

Most reps still sell the old way: pitching products, features, and benefits before they truly understand their buyer’s world.

The result? Endless “think it overs,” stalled deals, and buyers who never actually change.

Gap Selling exposes why this happens and teaches you to sell the way buyers actually make decisions by helping them see and feel the gap between where they are today and where they want to be.

What You’ll Learn

01
How to Diagnose
Learn to identify the root cause of your buyer’s problems, not just the symptoms, so your solution becomes the logical choice, not a lucky guess.
02
Psychology of Change
Understand how cognitive dissonance, self-determination, and the Zeigarnik Effect shape every buying decision and how to use them ethically to create urgency.
03
How to Build Massive Value
Quantify the business, operational, and emotional impacts of the status quo so your buyer clearly sees the cost of doing nothing.
04
How to Win More, Discount Less
When buyers believe you understand their world better than anyone else, price becomes a secondary factor and win rates skyrocket.

Gap Selling Is a System

This isn’t another “tips and tricks” sales book. It’s a complete problem-centric sales system built around one core idea:

People don’t buy products. They buy the outcomes those products enable.

Gap Selling gives you the tools to:

  • Diagnose buyer problems with precision

  • Quantify and qualify the impact of those problems

  • Link your solution directly to measurable business outcomes

Who It’s For

  • Account Executives tired of chasing unqualified deals
  • Sales Leaders looking for a repeatable, diagnostic sales framework
  • Enablement pros who want to coach reps beyond features and pitches
  • Founders who need a proven system to drive predictable revenue growth
