Venture Capital

Amplify Partners

Amplify Partners is an early-stage venture capital firm founded in 2012 and headquartered in Menlo Park, California, with a second office in San Francisco. Amplify positions itself as "the first investor for technical founders" — engineers, researchers, and scientists who have felt a problem viscerally and are compelled to spend a decade solving it. The firm invests primarily at the seed and Series A stages, with check sizes generally ranging from roughly $1M to $10M (often around $3M at seed), and continues to back companies through growth and IPO. Its thesis concentrates on deep technical categories: developer tools and computing infrastructure, machine learning and artificial intelligence, data and analytics, cybersecurity, and digital biology. In June 2025 Amplify announced roughly $900M in new capital across three vehicles — Fund 6, Fund 6 Select, and Amplify Bio. Notable portfolio companies include Datadog, Fastly, dbt Labs, Temporal, Chainguard, LangChain, Runway, and Recursion.

Cohort brief

Auto-generated

The 100 portfolio companies with APIs in the catalog, backed by Amplify Partners, scored on the Kin Score. Every figure below is computed from the catalog — nothing here is written.

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.

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.

This roster declares 114 members; 105 resolve to a provider in the catalog and 100 carry a score (95%). The figures above describe the scored members only.
Coverage caveat. 83 of 100 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.
