What happens when the agency you’ve built is just… stuck? Or when you hit a revenue ceiling, lose a major client, and start wondering if you’ve been playing the wrong game entirely? Those moments either break you or become the pivot points that redefine everything.

In this episode, you’ll hear from an agency owner who’s lived through the grind growing his agency from scratch, riding out recessions, choosing a niche that would help him get out of “no man’s land”. He’ll discuss the strategic bet that broke through plateaus, why he still refuses to hire a COO, and the million-dollar risk that could have sunk him but ended up being a worthwhile bet on his vision.

Alex Membrillo is the founder and CEO of Cardinal Digital Marketing, a 100-person specialist agency in healthcare performance marketing. Based in Atlanta, Alex launched Cardinal 16 years ago fresh out of college driven by equal parts ambition and desperation. Over the years, he’s navigated economic downturns, client churn, plateaus, and tough hiring markets, ultimately transforming it from a generalist digital shop into a niche powerhouse serving multi-site medical and dental groups nationwide.

In this episode, we’ll discuss:

• Riding out recessions.

• Breaking plateaus and choosing a niche.

• Why he still prefers not hiring a COO.

• Alex’s million-dollar bet on himself.

That first chapter didn’t exactly go as planned. The websites flopped, but an SEO win for a kayak tour company gave them the confidence (and proof) they needed to double down on search. From there, they expanded into paid ads and built a reputation on a simple promise: If we suck, we’ll give you your money back.

Riding Out Recessions & Staying Hands-On
