After years on the media-buying side spending over $100M and selling for firms like Verve, Starcom and Conde Nast, he started Big Happy in 2019 on a simple conviction: creative is a performance lever, not decoration.

Big Happy raised a $2.5M strategic round from Infolinks in 2024, was named Best Overall Mobile Marketing Company in the 2025 MarTech Breakthrough Awards, and in 2026 launched dynamic creative optimization for 3D DOOH and formed a board of advisors to scale creative-led omnichannel advertising.
