The 310 portfolio companies with APIs in the catalog, backed by
Index Ventures, 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.
