Case Study: ONE/SIZE achieves 35% YoY blended revenue growth with Fospha

How ONE/SIZE turned platform fluency into Q4 performance and 35% YoY blended revenue growth backed by daily measurement

ONE/SIZE, a TikTok-native beauty brand, faced the challenge of entering the Q4 peak season without reliable measurement to validate bold channel moves on Meta and TikTok. Their Meta account was fragmented and misaligned with platform algorithms, while on TikTok, a lack of conviction around the new GMV Max program made aggressive scaling a hard internal case to make. They partnered with Fospha for clear, actionable measurement.

Fospha provided full-funnel attribution that gave ONE/SIZE the confidence to act. On Meta, this meant consolidating campaigns based on Fospha's data, and on TikTok, it proved GMV Max's cross-channel halo effect. The results included a 35% YoY blended revenue growth, a 164% uplift in Meta ROAS, and a 421% uplift in TikTok ROAS. Fospha's measurement enabled these major platform shifts to deliver step-change results within a single quarter.
