We're joined by Brook Shepard, Founder of Mason Interactive, who brings 12 years of performance marketing experience scaling brands across ecommerce, education, and healthcare. Brook's focus on data-driven acquisition and AI-assisted creative testing gives him a grounded, practical view of where AI is actually moving the needle in paid advertising. Tune in to discover more about why most B2B marketing teams are either avoiding AI in their paid campaigns entirely or applying it without a clear system and wondering why it isn't working. Brook shares how to build a proper AI-assisted creative workflow, what a testing framework that produces a real signal looks like, and how lean startup teams can use AI to operate more efficiently without losing control of quality.
