This profile tracks Accel's identity and its portfolio graph across the API Evangelist network.
Firms are ranked by cumulative portfolio strength — how many highly-rated API companies they've backed, weighted by tier across composite quality and agent-readiness. The averages below are a secondary read on the typical company in the book.
Accel has 764 portfolio companies tracked on the APIs.io network, of which 316 (41%) publish APIs indexed here. The remaining 448 are tracked as profiles without a published API on the network.
Its highest-rated API providers on the network are Krux, Cdata, Algolia, Snyk, Ada Support.
Portfolio on the Network
Portfolio companies that publish APIs indexed on APIs.io, grouped by their
API Evangelist rating. Exemplar and Strong are expanded by default.
Exemplar28Complete, well-documented, and agent-ready
The 664 portfolio companies with APIs in the catalog, backed by
Accel, scored on the Kin Score. Every figure below is computed from
the catalog — nothing here is written.
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.

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.
This roster declares 764 members; 736
resolve to a provider in the catalog and 664 carry a score
(90%). The figures above describe the scored members only. Coverage caveat. 568 of 664 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
3 October 2026, across 28834
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.
