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.

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.
