# Growth Partner Index

> Growth Partner Index is a source-backed market map for evaluating performance growth agencies across paid media, influencer marketing, Amazon ads, retail media, performance creative, UGC, SEO/AI search, and B2B demand generation. The directory is operated by Fieldtrip, and Fieldtrip-affiliated listings are clearly disclosed.

Growth Partner Index uses a public Growth Partner Confidence Score methodology based on public evidence, category fit, proof of outcomes, creative-media integration, reputation, operating maturity, buyer fit, and freshness. Sponsored placements do not determine methodology scores.
