Case Study: Rookie achieves 5,000% ROI from creator partnerships with GRIN

How a nutritional supplement brand generates over 5,000% ROI from its creator program

Rookie, a health and wellness supplement company founded in 2021, needed a way to build a world-class creator program with a very small team. With only one person managing about 50 active creator partnerships per month, the team struggled to discover aligned creators, follow up consistently, track partnership performance, and nurture long-term relationships.

GRIN’s influencer marketing software gave Rookie a platform to manage every step of the creator workflow, including creator search, email sequences, relationship tags, affiliate deep linking, and report building. With GRIN, Rookie generated over 222K video views, 1.4M+ impressions, and $53 in earned media value for every $1 spent, helping the brand scale creator partnerships while staying organized and efficient.
