| Stage 1 Upstream trust before market share | AgEvidence does not ask producers to abandon tools. It helps funded agtech companies express their own records as portable evidence: event-first systems emit interventions and observations, source-record-first systems emit original records with manifests, lineage, units, timestamps, and transformation history. SDK, schemas, CLI, fixtures, and verifier make implementation testable without a sales process. | The early win is semantic reuse, not revenue. If several source systems express evidence through the same small vocabulary, that vocabulary becomes the default export shape. |
| Stage 2 Integration becomes configuration | Repeat integrations convert into workspace profiles, schema mappings, fixtures, conformance tests, and review artifacts. New upstream systems no longer require a bespoke platform integration to be useful downstream. | A vertical platform must persuade each upstream provider to integrate into its proprietary workflow. An evidence contract instead makes the provider's own export portable across every destination. |
| Stage 3 Reference models move the calculation layer upward | Open work does not need to claim regulatory standing. It only needs calculations that are reproducible, versioned, inspectable, and bounded: schemas and receipt envelopes, SDK and verifier, model input manifests and run lineage, reference examples, allocation and duplicate-claim controls, jurisdiction profiles, reliance bundles. | Proprietary software then competes against a public baseline. Buyers can ask what value remains above the reproducible reference implementation. |
| Stage 4 Insetting becomes claim allocation | One intervention can support several forms of institutional reliance at once. The question becomes who may legitimately rely on which portion of an outcome, under which accounting system, without double claiming. | If that question is answered at the evidence layer, the marketplace becomes modular. Transaction, financing, and aggregation still matter; custody of the allocation logic does not have to. |
| Stage 5 Portable verification escapes the platform | A verifier that runs outside any single platform can check structure, signatures, temporal provenance, model versions, source lineage, allocation rules, duplicate-claim controls, and profile conformance independently. | The trust boundary moves. Instead of asking a platform for assurance, a buyer, processor, auditor, university, or administrator inspects the bundle itself. |
