Felicis Ventures
Felicis Ventures is an early-stage venture capital firm founded in 2006 by Aydin Senkut and headquartered in Menlo Park, California. The firm backs founders "who rewrite the rules," concentrating the majority of its capital at Seed and Series A while also participating in Series B and select growth rounds, with reported assets under management of roughly $2.4B and a tenth flagship fund (FV X) of $900M closed in June 2025. Typical checks range from about $2M to $40M. Felicis is thesis-driven across artificial intelligence, cybersecurity and defense, global resilience and energy, health and bio, infrastructure, and vertical SaaS, and invests globally (backing founders from 40+ countries rather than only Silicon Valley). The firm leads or co-leads a large share of its deals, sources most new investments through founder referrals, and is known for founder-friendly practices including a commitment to vote with founders on board matters and a "1% Founder Development Pledge." Its portfolio and exits include Shopify, Adyen, Canva, Notion, Credit Karma, Fitbit, Guardant Health, Docker, PagerDuty, Twitch, Supabase, and Runway.
Felicis Ventures has 211 portfolio companies tracked on the APIs.io network, of which 94 (45%) publish APIs indexed here. The remaining 117 are tracked as profiles without a published API on the network.
Its highest-rated API providers on the network are Plaid, Shopify, Canva, Diffbot, Adyen.

Cohort brief
Auto-generatedThe 202 portfolio companies with APIs in the catalog, backed by Felicis 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 | 33.4 | 26.5 | +6.9 | 202 |
| Operational Transparency | 16.9 | 13.2 | +3.7 | 202 |
| Developer Ergonomics | 26.5 | 23.8 | +2.7 | 202 |
| Discoverability | 59.7 | 58 | +1.7 | 202 |
| Contract Quality | 17.7 | 17.7 | 0 | 202 |
| Contract Governance | 6.4 | 7 | -0.6 | 202 |
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) | 29% | 15% | +14 |
| MCP server (first-party) | 28% | 13% | +15 |
| Agent Skills | 0% | 0% | 0 |
| OAuth scopes | 14% | 12% | +2 |
| Security | 100% | 98% | +2 |
| Arazzo workflows | 2% | 2% | 0 |
| Governance rules | 11% | 18% | -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. 179 of 202 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.
