Manage rolling rosters of micro-influencers (5k–50k followers) for niche B2C apps and products, handling outreach, contracting, performance tracking, and roster culling. Charge app founders a management fee or per-placement fee to run their UGC campaigns, since this channel consistently outperforms paid ads for niche products. The founder credits this as the single highest-ROI channel that scaled the app from hobby revenue to sustainable income.
