# 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 publishes the Growth Partner Confidence Score (v1.1): Published score = proof (max 25) + category fit (20) + creative-media integration (15) + reputation signals (15) + operating maturity (10) + buyer-fit clarity (10) + evidence freshness (5), rounded once to one decimal. Ties are broken by name, A to Z. Most pillar points are legacy curated assessments, re-derived arithmetically and published as provisional public-evidence assessments. Affiliation and paid placement are not scoring inputs; ownership and every affiliation are documented on the Fieldtrip network page. Category pages default to a labelled "Recommended" presentation order which prioritises Fieldtrip-affiliated agencies; score-only sorts and the ranked top lists are unaffected. ## Core Pages - [Homepage](https://growthpartnerindex.com/): Overview of the directory and categories. - [Browse all agencies](https://growthpartnerindex.com/agencies): Filter and compare every listed agency. - [Methodology](https://growthpartnerindex.com/methodology): Growth Partner Confidence Score, source policy, disclosure policy, corrections process, and update cadence. - [About & disclosure](https://growthpartnerindex.com/about): Ownership, editorial policy, and the Fieldtrip relationship. - [Jake Jorgovan](https://growthpartnerindex.com/blog/authors/jake-jorgovan): Author profile — agency operations and B2B marketing; discloses a founder connection to Content Allies, a Fieldtrip-affiliated agency. - [Ioana Cozma](https://growthpartnerindex.com/blog/authors/ioana-cozma): Editorial reviewer profile — SEO and marketing content; discloses a contributor connection to inBeat, a Fieldtrip-affiliated agency.
