Sebastian
Founder & Head of Growth
Sebastian has spent his career running paid media accounts where the budget is real and the tolerance for guesswork is zero — managing multi-platform campaigns for a roster of consumer brands before founding Unmastered. He built the agency on a simple frustration: too many brands were getting reports that looked good and results that didn't. Based in Santo Domingo and working with brands across borders and timezones.
Every engagement starts and stays with the founding team. We cap the number of clients we take so that never has to change.
