Cohort brief
Auto-generatedThe 115 portfolio companies with APIs in the catalog, backed by Founder Collective, scored on the Kin Score. Every figure below is computed from the catalog — nothing here is written.
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Developer Ergonomics | 27.4 | 23.8 | +3.6 | 115 |
| Access Clarity | 28.8 | 26.5 | +2.3 | 115 |

| Contract Governance | 6.5 | 7 | -0.5 | 115 |
| Contract Quality | 16.9 | 17.7 | -0.8 | 115 |
A facet is averaged over the members that carry it, not over the whole cohort — the “Scored” column is that count. Averaging an absent facet as zero would score our own coverage gaps as the providers’ posture.

Coverage caveat. 101 of 115 scored members had under half their catalog-attributable points satisfied at all (catalog_earned / catalog_max < 0.5). They are INCLUDED in the mean above. A large share here means the cohort mean is partly a measurement of how far our enrichment reached, not only of how these providers publish.Generated from the catalog build of 2 November 2026, across 37080 providers, using the same computation served by the APIs.io cohort API. Briefs are published for rosters of 5 or more scored providers; below that a distribution is not meaningful.
