Case Study: Sweaty Betty achieves a 2.3% AOV uplift with Fospha’s causal measurement

Sweaty Betty lifts AOV 2.3% with Fospha

Sweaty Betty, a female-first activewear brand, faced a challenge in proving the long-term commercial impact of its brand investment. Without causal evidence, defending this budget to internal finance teams was difficult. The marketing team needed a data-driven solution to bridge the gap and establish a single, shared view of how brand spend drives results, which led them to partner with Fospha.

Fospha implemented its Glow product, a causal measurement layer that uses Bayesian network modeling to connect awareness spend to downstream outcomes. The solution identified engaged visits and branded search impressions as leading indicators of success. This provided measurable proof of brand impact and led to a 2.3% uplift in average order value among new customers. Fospha gave both marketing and finance teams a shared evidence base, changing the internal conversation and allowing Sweaty Betty to confidently scale its brand investment.
