Welcome to Agency Business.

This week, Olivia and Brian interview Josh Rosenberg, co-founder and CEO of Day One Agency, the creative shop founded 11 years ago to bridge the gap between earned media and brand storytelling. With offices in New York, Los Angeles, Chicago, and Portland, Day One works with clients including American Express, Chipotle, Nike, Converse, and e.l.f. Beauty.

Josh shares how Day One was built around what he calls “earned creativity”—an approach that pairs editorial thinking with culturally relevant storytelling. He explains why curiosity has become the most essential trait in the age of AI, how the agency’s apprenticeship program helps identify emerging talent, and why Day One created its Learning Fund, a $30,000 internal grant program for employees to pursue continued education.

The group discusses how Day One resists adding a media practice in favor of deeper creative partnerships, how editorial projects like Ask Gen Z and a new Gen Alpha research report inform client work, and why investing in in-house content such as podcasts and newsletters fuels both learning and new business. Josh also details how the agency’s structure—organized around its Shape, Share, and Fuel teams—keeps it nimble and “built for change.”
