About

The specialist you meet is the specialist you get. That's the whole org chart.

Founder-led
Every account, no handoffs
10+ yrs
Experience per specialist
Capped
Client roster, by design

Built by the people big agencies put on the pitch, then take off the account.

We kept watching the same thing happen from inside larger agencies: senior people win the client, junior people inherit the work. Unmastered exists to remove that handoff.

Founder-led

The person on the pitch runs the account.

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.

How the team is built

  • Ten-plus years of experience per specialist — that's the hiring bar, not an average we round up to
  • Every specialist has personally run serious budgets and shipped real campaigns — not supervised them from a dashboard
  • Discipline specialists — paid social, search, lifecycle, content — matched to what your brand actually needs
  • A small client roster on purpose — senior people doing the work doesn't stretch to 100 accounts, and we're fine with that
What we don't do

The short list of things we'll say no to.

Work we'd be mediocre at

No SEO retainers, no web development, no PR. We'll happily point you to specialists we trust — we just won't invoice you for work outside our lane.

Accounts we can't help

If the audit shows your real bottleneck is the product, the pricing, or the operations — not the marketing — we'll tell you on the first call, instead of taking six months of retainer to prove it.

Locked-in contracts

Month-to-month after the initial ramp-up. Your accounts, your data, your learnings — documented in your workspace, not held hostage in ours.
