The problem with persuasion

Generic marketing wastes persuasion capital. Scarcity messages show zero average effect on populations. But on personality-matched segments, they're powerful.

The difference isn't the tactic — it's the targeting. A scarcity message that falls flat on an ENFP can convert instantly on an ISTJ. Social proof that annoys a Type 5 can seal the deal for a Type 3.

STEP 03

Get actionable intelligence

Persuasion tactics ranked by effectiveness. Objections predicted before they arise. Pricing frames that match their psychology. Content that speaks their language.

Under the hood

Hybrid engine: a 548K deterministic knowledge graph — covering OCEAN buyer traits, Socionics buying styles, Enneagram purchase motivations, Hofstede cultural dimensions, and Cialdini persuasion maps — enriched by Claude Sonnet for contextual pitch and strategy generation. The maps are fixed and auditable. The generation layer adds nuance.

Seven endpoints, one unfair advantage

Cialdini × Personality

6 principles, infinite combos

Cialdini's influence principles — reciprocity, commitment, social proof, authority, liking, scarcity — don't apply equally to everyone. Personality type determines which principles convert and which backfire.

Hofstede Cultural Dimensions

70+ countries mapped

Power distance, individualism, uncertainty avoidance, and time orientation shape buying behavior as much as personality. KYB combines both layers for cross-cultural selling intelligence.

Two modes of precision

KYB works with or without KYH — but the gap is massive.

🔮
MODE 1 — PRECISION

With KYH Profile

Pass a full KYH personality profile and KYB maps persuasion to this exact person — their cognitive type, decision style, emotional triggers, cultural context, and value hierarchy.

Confidence
~95%
💬
MODE 2 — INFERRED

From Description Only

No personality data? Pass a text description of the buyer and KYB infers what it can — general patterns from demographics, context clues, and behavioral signals. Better than nothing, but you're leaving precision on the table.
