Social Case Studies
Build vibrant communities. Drive app downloads and user engagement through authentic creators who showcase the power of connection.
The Challenge
Stereo, a fast-paced social app built around viral voice notes and spontaneous conversations, needed a scalable way to continuously acquire new users while keeping CPIs low and ad fatigue under control. The challenge was clear: Traditional performance ads quickly burned out on TikTok and Meta Creative fatigue drove CPI up and retention down Stereo needed a constant flow of fresh creator content to test at scale They required data-backed creative insights to discover winning hooks Performance had to be maintainable month after month, not just campaign-based Stereo needed a partner that could deliver a repeatable UGC testing engine to find high-performing ad creators—fast.
The Solution
Stereo partnered with SHOUT to build an always-on creator testing pipeline. Each month, we: Recruited new creators across comedy, viral reaction, gaming, and lifestyle niches Delivered 56 UGC video ads monthly for continuous testing Focused on performance hooks, strong CTAs, and install-driven messaging Tested voice note reactions, duets, debate-style hooks, and conversation challenges Used data from ad performance to refine scripts and creative formats Scaled best-performers into paid campaigns while rotating in fresh content This system gave Stereo a constant stream of thumb-stopping creatives for TikTok and Meta, helping reduce CPIs and improve retention quality—month after month.
