Paradigm
Paradigm is a research-driven, frontier-technology investment firm founded in 2018 by Coinbase co-founder Fred Ehrsam and former Sequoia Capital partner Matt Huang. Headquartered in San Francisco with offices in New York and Washington, DC, the firm began as one of the largest crypto-focused venture funds and has since expanded to build and invest across crypto, AI, robotics, and other technical frontiers "from first check through to public markets." Paradigm is unusual in that it is both a builder and an investor: alongside its fund it ships open-source software (Reth, Foundry, Alloy, Artemis) and incubates companies. The firm has made 130+ investments and reported roughly $12.7B in assets under management as of April 2025; it raised a $2.5B first venture fund in 2021 and announced a new $1.2B fund in July 2026 aimed at the "technical frontier" including AI and robotics. Notable portfolio companies and protocols include Uniswap, Coinbase, Stripe, Optimism, Chainalysis, Fireblocks, Blur, Monad, Kalshi, and Zipline. Managing partners include Matt Huang and Alana Palmedo.
Paradigm has 103 portfolio companies tracked on the APIs.io network, of which 103 (100%) publish APIs indexed here.

Cohort brief
Auto-generatedThe 100 portfolio companies with APIs in the catalog, backed by Paradigm, scored on the Kin Score. Every figure below is computed from the catalog — nothing here is written.
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Developer Ergonomics | 34.9 | 17.9 | +17 | 100 |
| Contract Quality | 28.7 | 17.5 | +11.2 | 100 |

| Contract Governance | 9 | 6.4 | +2.6 | 100 |
| Access Clarity | 22 | 22.3 | -0.3 | 100 |
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) | 35% | 16% | +19 |
| MCP server (first-party) | 16% | 7% | +9 |
