The second-buyer test
A proposed experiment to distinguish a reusable acceptance network from repeated bespoke integration work.
A precise, testable hypothesis
A second independent buyer can onboard an already-profiled supplier with less active human effort by reusing its service profile, integration and permitted evidence—while retaining its own authority and risk decisions.
The experiment targets repeatable commercial value. Registration totals and simulated agent traffic would not establish that value.
The proposed experiment
- Choose one service class. Define a bounded digital deliverable and machine-checkable acceptance criteria where appropriate.
- Establish Buyer A. Record supplier onboarding work, permissions, evidence requirements, exceptions and acceptance outcomes.
- Introduce independent Buyer B. Offer only the profile, integration and evidence that may legitimately be reused.
- Measure the difference. Compare active onboarding time, technical effort, human review, exceptions and actual commercial commitment.
The proposed validation threshold
The founding plan targets two independent paying buyers and three suppliers reused by Buyer B, with at least a 50% reduction in active onboarding time. These are proposed targets, not achieved metrics.
The measurement must include residual review and integration costs. Both buyers should evaluate a sufficiently comparable service so that a faster second onboarding is not merely the result of a simpler requirement.
How to interpret the result
If Buyer B can reuse permitted information and reach its own acceptance decision with materially less work, the result supports a narrow network hypothesis. It does not yet establish general adoption, global scale or performance across unrelated service classes.
If every buyer must repeat nearly all onboarding and integration work, the result points toward a service or integration business. That outcome should change the network thesis and the next experiment.
