My guest on this episode of the podcast is Olivia Kory , the Chief Strategy Officer of Haus , an advertising measurement platform. Against the backdrop of tariffs and economic uncertainty, Olivia and I discussed how firms can think about assessing the efficiency of their marketing spend. Among other topics, we cover: Why the open web is so foreign to many performance advertisers; The right way to conceive of platform A/B testing tools that automatically optimize targeting; How advertisers are auditing their measurement solutions in light of the tariffs and economic volatility; What steps marketing teams can take to "get fit" ahead of a potential economic recession.
