Moonlighting to the Mainstage: Sam Piliero on Reinventing Media Buying for Challenger Brands

In this episode of Agency Alchemy, we speak with Sam Piliero, founder of The Moonlighters, a fast-growing performance marketing agency built for the $1–$10M e-commerce brand. From scaling BarkBox through an IPO to launching his own agency, Sam shares how he’s rewriting the rules of media buying—eschewing bloated teams, cutting wasted ad spend, and proving that founder-led content can outpace traditional agency marketing. Sam digs into the challenges small but ambitious DTC brands face, why Facebook and Google’s “easy mode” can cripple growth, and how The Moonlighters’ one-to-one senior talent model is changing client relationships. Sam also offers candid thoughts on AI’s potential in media buying, the power of giving away the “secret sauce” on YouTube, and his vision for sustainable agency growth.
