Case Study: ThredUp Drives New Purchasers with Haus

ThredUp lifts new purchasers 1.53% with Haus

ThredUp, one of the world's largest online resale platforms, wanted to attract more new customers and scale its presence on Pinterest, a channel where it believed its target audience was highly engaged. To accurately measure the platform's true impact, which was difficult with their existing attribution methods, they turned to vendor Haus and its GeoLift product to design a test.

Haus implemented a two-cell holdout test for ThredUp that ran for five weeks with a two-week post-treatment window. The test results exceeded expectations, driving a 1.53% lift in new purchasers and achieving a cost per incremental action that was 40% lower than their goal. Based on these decisive results, ThredUp plans to significantly scale its investment in Pinterest, with Haus becoming an integral part of its growth marketing strategy.
