Ybera USA was already running a mature Meta account with its own influencer whitelisting, seasonal sales, catalog ads, retargeting, studio creative, and AI-generated ads. The problem was the one every scaling brand hits: cold-traffic creative that converts well without a discount is rare, and as spend grew, cost per purchase climbed. Ybera needed a repeatable pipeline of authentic creator content that could hold efficiency at scale, without raising ad budgets or giving away margin.
Ybera activated 203 US micro-influencers on Instagram through Stack Influence over three months. 19 creator posts were whitelisted as Meta Partnership Ads, running from each creator's own handle to cold audiences. Ybera layered the ads in during the campaign, cut the losers within days, and scaled 4 winners for the seven months after the campaign ended.
Meta Partnership Ads cut Ybera's cost per purchase by 21% and lifted conversion rate 73%, delivering $288K in sales and a 4.6X return on a $6K Stack campaign and $56K in ad spend
