Case Study: Andie Swim Achieves 10X More TikTok Value Visibility with Fospha

How Andie Swim is Making Waves with TikTok Ads

Andie Swim, a US luxury swimwear brand, partnered with Fospha to overcome the limitations of last-click measurement as they scaled. Using Fospha’s Measurement OS/full-funnel attribution, the team gained clearer visibility into marketing performance and the true impact of channels like TikTok.

With Fospha’s modeling in place, Andie Swim discovered TikTok was driving 9.5X more conversions than last-click reported, and paid social overall was delivering 3.4X more conversions than previously credited. After relaunching TikTok ads, the brand increased TikTok spend from 5% to 13% of paid social spend in two months, grew weekly channel revenue by more than 5X, and saw 65% of TikTok conversions come from new customers, with CPA 25% below the cross-channel average by June.
