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.
