How Underoutfit Gained Confidence to Scale Spend

Click-based models underestimate paid social

Prior to FosphaUnderoutfit used Triple Whale and focused on scaling their Meta conversion activity. However, over time they experienced limited scalability for growth in Meta and started running out of headroom to spend in their conversion-focused strategy. Their co-founder Felix realised they needed to a more diverse channel mix but they needed a full-funnel measurement tool that could prove the value of upper funnel spend. 

Click-based modelling significantly undervalues upper funnel activity, and in the case of Underoutfit, TikTok was having 9X greater impact on revenue than Underoutfits click-based model identified. 

Equipped with Fospha's evidence of the untapped value of their upper funnel, Underoutfit were able to adopt an omni-channel approach with brilliant results.
