The short answer
To find Amazon influencers, scroll to the "Videos for this product" section on your competitor's Amazon product pages — every creator listed is an Amazon Influencer. Browse Amazon Live by category for more. For scale, use a creator database like Hubfluence to filter thousands of TikTok, Instagram, and YouTube creators who already link an Amazon storefront in bio.
The winning offer is product seeding + inclusion on their storefront + an on-product review video, letting them earn the standard Amazon Associates commission. Some creators also take a $50–$300 flat fee for video production.
