About this Episode

Most agency owners think about growth as winning more clients or hiring more people. This episode offers a different frame. Sei-Wook Kim, co-founder and Vice Chairman at Barrel Holdings, has spent years building a portfolio of independently operated, specialized agencies and the operating principles behind that work are just as relevant for owners who have no plans to acquire. You'll understand what makes an agency genuinely durable, how to read the true health of a business beneath its reported financials, and why the fundamentals — specialization, recurring revenue, strong leadership — matter whether you're buying or building. A grounded look at what sustainable agency growth actually requires.
