Cohort brief
Auto-generatedThe 172 portfolio companies with APIs in the catalog, backed by Balderton Capital, scored on the Kin Score. Every figure below is computed from the catalog — nothing here is written.
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Access Clarity | 28.2 | 26.5 | +1.7 | 172 |
| Operational Transparency | 13.3 | 13.2 | +0.1 | 172 |
| Contract Quality | 17.5 | 17.7 | -0.2 | 172 |
| Contract Governance | 6.2 | 7 | -0.8 | 172 |
| Developer Ergonomics | 22.8 | 23.8 | -1 | 172 |
| Discoverability | 56.8 | 58 | -1.2 | 172 |
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.
| Artifact | This cohort | Catalog | Difference |
|---|---|---|---|
| MCP server (any) | 19% | 15% | +4 |
| MCP server (first-party) | 17% | 13% | +4 |
| Agent Skills | 0% | 0% | 0 |
| OAuth scopes | 16% | 12% | +4 |

mcp_pct counts any mcp/ artifact including ones API Evangelist derived from the provider OpenAPI; mcp_first_party_pct counts only servers the provider publishes. Prefer the latter.

Coverage caveat. 154 of 172 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.
