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.
SV Angel has 141 portfolio companies tracked on the APIs.io network, of which 92 (65%) publish APIs indexed here. The remaining 49 are tracked as profiles without a published API on the network.
Its highest-rated API providers on the network are Twilio, Anthropic, io, Stripe, ElevenLabs.

Cohort brief
Auto-generatedThe 136 portfolio companies with APIs in the catalog, backed by SV Angel, scored on the Kin Score. Every figure below is computed from the catalog — nothing here is written.
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Operational Transparency | 28.9 | 13.2 | +15.7 | 136 |
| Contract Quality | 32.8 | 17.7 | +15.1 | 136 |
| Developer Ergonomics | 34.8 | 23.8 | +11 | 136 |
| Access Clarity | 36.8 | 26.5 | +10.3 | 136 |
| Discoverability | 62.3 | 58 | +4.3 | 136 |
| Contract Governance | 11.3 | 7 | +4.3 | 136 |
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.
| Artifact | This cohort | Catalog | Difference |
|---|---|---|---|
| MCP server (any) | 34% | 15% | +19 |
| MCP server (first-party) | 33% | 13% | +20 |
| Agent Skills | 0% | 0% | 0 |
| OAuth scopes | 19% | 12% | +7 |

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.

Coverage caveat. 103 of 136 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 2 November 2026, across 37080 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.
