About the hosts
Peter Kang and Sei-Wook Kim are co-founders of Barrel Holdings, a company built around the idea that agencies can be both creatively excellent and operationally sound, with the right habits in place.
They started their first agency together nearly two decades ago. Since then, they’ve weathered feast-or-famine cycles, made their share of missteps, and slowly shaped a clearer, more sustainable way of running agency businesses.
Today, through Barrel Holdings, they support a growing portfolio of specialized agencies. But they still think like operators. They still wonder if the margins make sense. They still ask where the process broke.
The AgencyHabits Podcast is their way of sharing what they’re seeing and learning, not as blueprints, but as open-source reflections. If something they’ve tried helps you make a better decision in your own agency, that’s the whole point.
“Having known Peter and Sei-Wook for a long time, it’s great to hear them share their journey while providing useful insights for other agency founders.”
