How to be Profitable at Any Size, With Drew McLellan
About this Episode In this episode of the Agency Profit Podcast, Marcel Petitpas is joined by Drew McLellan, founder of Agency Management Institute, to unpack what profitability really looks like at different stages of agency growth. Drawing on decades of experience and financial data from more than 250 agencies, Drew explains why every agency can be profitable—regardless of size—and why many owners mistakenly believe their stage makes profitability impossible. Together, they explore common growth “breaking points,” the tradeoffs between lifestyle businesses and scalable firms, and why running an agency by the numbers is non-negotiable. From the realities of hiring, specialization, and management layers to how AI is reshaping what agencies should actually charge for, this conversation gives agency owners a grounded, experience-driven roadmap for building a more resilient, profitable business—without chasing hype or false benchmarks.
