Forerunner Ventures
Forerunner Ventures is an early-stage venture capital firm founded in 2012 by Kirsten Green and headquartered in San Francisco, California. Forerunner backs founders building category-defining companies, investing with early conviction at the seed and Series A stages (with selective pre-seed), typically writing initial checks in the $1M-$15M range. The firm invests across consumer, commerce, health and wellness, consumer finance, marketplaces and services, personal systems, and platforms and infrastructure, increasingly viewed through AI lenses (AI as agent, AI as infrastructure, AI as intelligence layer). Forerunner has raised nearly $3B in assets under management across seven flagship funds, with its most recent Fund VII a $500M early-stage vehicle. Its portfolio includes category leaders such as Chime, Warby Parker, Glossier, Hims & Hers, Oura, Faire, The Farmer's Dog, Dollar Shave Club, Curology, Away, Ritual, and Chime, along with a growing cohort of AI-native companies including Decagon, Suno, Slingshot AI, and Monarch Money.

Its highest-rated API providers on the network are Natural AI, Oura, Viewpoints AI, Chime, MagicX.

Cohort brief
Auto-generatedThe 74 portfolio companies with APIs in the catalog, backed by Forerunner Ventures, scored on the Kin Score. Every figure below is computed from the catalog — nothing here is written.
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Access Clarity | 27.6 | 26.4 | +1.2 | 74 |
| Contract Governance | 4.1 | 6.3 | -2.2 | 74 |
| Discoverability | 54.9 | 58.2 | -3.3 | 74 |
| Operational Transparency | 6.8 | 13.6 | -6.8 | 74 |
| Developer Ergonomics | 14.2 | 23.1 | -8.9 | 74 |
| Contract Quality | 5.4 | 17.6 | -12.2 | 74 |
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) | 16% | 15% | +1 |
| MCP server (first-party) | 14% | 12% | +2 |

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. 70 of 74 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.
