The $100B Problem That’s Costing Ecom Brands Big, with LEAF

Tash Courtenay-Smith

Gilbert Corrales and Wes Hartley, co-founders of LEAF, join Tash to expose a silent killer in the world of e-commerce: broken conversion tracking. 

With backgrounds in music tech and data engineering, Gil and Wes have built one of the most sophisticated performance agencies in the UK – one that isn't afraid to tell brands the truth.

In this deep-dive episode, they reveal how poor tracking is wasting billions in ad spend, why transparency matters more than ROAS, and how brands can take back control of their data. From running one of Latin America’s biggest music platforms to auditing 10,000 ecom sites, their insights are a wake-up call for any brand serious about scaling sustainably.
