Angel

SV Angel

SV Angel is a San Francisco-based venture capital firm founded in 2009 by Ron Conway, one of Silicon Valley's most prolific angel investors. The firm runs two vehicles: an early-stage Seed Fund that writes roughly $200k checks into pre-seed and seed rounds, and a later-stage Growth Fund that invests at Series B and beyond. SV Angel is a founder-first, high-conviction investor that deliberately does not lead rounds, takes no board seats, and writes smaller checks as part of a larger syndicate so it can act as a neutral "routing layer" and advocate for founders. It is famous for its "Inflection Point Approach" — showing up at critical moments around fundraising, M&A, and business development. The firm invests almost entirely in US-based, software-driven companies across consumer and enterprise, and its portfolio has produced dozens of unicorns and landmark outcomes including Google, Airbnb, Coinbase, Stripe, Slack, Instacart, DoorDash, Reddit, Pinterest, GitHub, Databricks, Anthropic, and OpenAI.

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.
