Venture Capital

CRV

CRV (formerly Charles River Ventures) is one of the oldest venture capital firms in the United States, founded in 1970 to commercialize research coming out of MIT. The firm invests early — primarily at the Seed and Series A stages, with occasional Series B — leading rounds in enterprise, consumer, developer tools, security, data infrastructure, AI, and bioengineering companies. CRV has backed more than 750 companies since inception across 18 funds, raising over $4.3 billion (including a recent $600M early-stage fund), and has seen 80-plus of its portfolio companies reach public-company status. Notable investments include DoorDash, Airtable, HubSpot, Datadog, Zendesk, Patreon, Mercury, Vercel, Cursor, Postman, Kong, Tailscale, Ring, and PillPack. The firm is headquartered in San Francisco (52 Zoe Street) with a long-standing Bay Area presence and offices in Menlo Park, CA and Cambridge, MA.

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 154 members; 141 resolve to a provider in the catalog and 138 carry a score (98%). The figures above describe the scored members only.
Coverage caveat. 109 of 138 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.
