Growth Partner Index is operated by Fieldtrip. Fieldtrip ownership and every affiliated agency are documented on the Fieldtrip network page. On category pages the default “Recommended” order prioritises eligible Fieldtrip-affiliated agencies; score-only sorts and the evidence-based top lists are ordered by published score alone. All listings are scored with the same published formula from provider-reported and public source material, and affiliation or sponsorship is never a scoring input.
