Our Story

Built by advertisers,
for ambitious
brands

Growth Harbor LLC was founded with one belief: every dollar you spend on advertising should work as hard as possible. We're the team that makes that happen — with data, creativity, and radical transparency.

Our Mission

Performance advertising shouldn't be a black box

Too many agencies hide behind jargon and vague promises. We built the agency we wished existed when we were on the client side — one that shows you exactly where every dollar goes.

Founded in 2019 by ex-Google, Meta, and agency veterans, Growth Harbor has grown to a 45+ person team managing over $50M in annual ad spend for 300+ clients.

True partnership
We treat your budget like it's our own. Your wins are our wins. We're invested in your long-term success, not just retainers.

Results shouldn't take six months. Our agile process means meaningful improvements in weeks, not quarters.

FAQ

Common questions

No. Our fees are flat monthly retainers. This aligns our incentives with your results, not your budget size. We'll never encourage you to spend more than you should.

We start with a 3-month initial engagement — paid advertising takes time to properly optimize — then move to month-to-month after that. We earn your business every single month.

Most clients see meaningful improvement within 30 days. Major results typically take 60–90 days as we gather data, test, and optimize. We set clear milestones upfront.

A complete review of your ad accounts, competitor landscape, and opportunity gaps — delivered in a 60-minute call with a senior strategist. Free, no strings attached.

Absolutely. We work with clients across North America, Europe, Australia, and Southeast Asia. Our team operates across multiple time zones for responsive service.
