Turn your biggest fans into a word-of-mouth sales channel — ambassadors, affiliates & creators. Roster turns customers who love you into ambassadors, affiliates, creators — all in one platform built for Shopify. Recruit from your own buyers, launch campaigns that generate authentic UGC, and auto-issue Smart Links and leak-proof discount codes. Product seeding fulfills thru Shopify, automated payouts with 1099 handling, and every sale is tracked back to the ambassador who drove it. Scale word-of-mouth without the manual work and media spend — or the commission of a creator marketplace. 1.
