B2B verification's problem isn't the rules but the design. Dumb friction — repeated data entry, unexplained requests, vague statuses — should become smart friction: relevant controls, reused evidence, clear next steps. The framework: start from the evidence journey, not the form; define purpose, source, freshness, confidence, action per item; layer experience, orchestration, evidence, policy, records; design for business, operator, auditor; measure speed with control quality.

High profile failures like Theranos and Frank reveal what happens when investors buy narratives instead of inspecting data. Capital protection requires structural verification: multi signature authorizations, staged tranches tied to verifiable milestones, independent auditing and focusing on metrics that resist fabrication.
