Game Theory Sales Based. A five-layer strategic sales model built from 12 years of high-performance commercial leadership and academic game theory. It does not teach salespeople what to say. It teaches them how to think.
"The rep who memorises the best pitch will lose to the rep who understands the game. GTSB teaches salespeople to identify the game, read the player, control the information, and adapt when the rules change."
Each layer builds on the last. Together they form a complete strategic operating system for every sales interaction. The full methodology, archetype system, and training protocols are delivered exclusively through KCS engagements.
Not all sales interactions are the same game. Zero-sum, non-zero-sum, and repeated game structures each demand a fundamentally different strategy. Applying the wrong approach to the wrong game type is the most common reason skilled reps lose winnable deals.
Every buyer belongs to one of four archetypes, each with a predictable dominant strategy. Identify the archetype in the first 90 seconds and you can prepare your optimal response before the buyer makes their first move. Identification draws on three indicators: Knowledge, Sentiment, and Experience.
Life stage determines what a buyer is trying to protect, gain, or prove. Two people with identical job titles and budgets can have completely opposing decision logic based solely on where they are in life. GTSB trains reps to read life cycle signals and adjust positioning, language, and priority framing accordingly.
Every sales conversation is an information game. GTSB trains reps to use backward induction: deciding the desired outcome first, then designing questions that extract what is needed to get there. Three filters evaluate information quality: Knowledge, Sentiment, and Experience. The buyer's stated objection is rarely the real objection.
No game stays the same. Temporal, emotional, and environmental variables change the rules mid-conversation. The rep who detects when the game has changed and adapts without losing control of the frame is the rep who closes consistently across every environment, every buyer, and every objection.
Most sales training teaches transactional behaviours: pitch, handle objection, close. GTSB teaches strategic thinking: identify the game, read the player, control the information, and adapt when the rules change. The result is salespeople who do not just hit target. They break it.
