If Your Agency Only Knows How to Run Ads, Don’t Expect Them to Grow a Brand.

Most brands don’t have a performance problem—they have a leadership gap.

15 October 2025


I’m a CMO who’s scaled a PE-backed DTC brand from the inside—driving 220% growth and overseeing $125M+ in paid media. I bring that and now the Fractional CMO perspective on agency partners with an operator’s lens and perspective on what makes agency partnerships actually work.

Built campaigns. Written briefs. Sat in ad accounts at midnight trying to figure out why something that should be working isn’t.

Here’s the truth: most agencies aren’t great.

Not because they’re lazy—because they’re not built for accountability.

Talent’s thin. They don’t really understand your business or your customers.

And too many come in convinced they can do it better than you.


The silver bullet that never is

Founders bring in agencies hoping for relief.

Someone to make marketing easier. Someone to “own it.”

Sometimes it’s a gut check for the team.

Sometimes it’s because the team’s maxed out.

Neither is wrong. But that’s where it starts to slide.

Because before long, the agency’s not supplementing your team—they’re replacing it.

And you’re paying people to relearn what your own team already knows.

Agencies should help you go faster, not reset the clock.

They should fill skill gaps, test new ideas, expand capacity.

Analytics? Always in-house. Always your source of truth.

Most agencies can perform.

But few understand how to build a brand that lasts.

They know how to spend your ad dollars.

Not how to make them compound. Not how to lower CAC and improve LTV.


Ads aren’t just ads

Too many agencies treat media like a finish line: launch, optimize, report, repeat.

Here’s the thing—ads don’t just drive the sale. They shape the experience.

Every ad is a micro-interaction with your brand.

The tone, the creative, the offer—it all teaches people what to expect from you.

When you pay attention, ads tell you what customers value and what keeps them coming back.

Too many agencies treat media like a finish line: launch, optimize, report, repeat.

But the best brands use ads as a live research loop.

Every impression, click, and conversion is unfiltered feedback.

It’s not just what people say—they’re voting with their wallets.

Smart teams feed that data back into everything:

Creative wins inspire product ideas & high-performing hooks reshape landing pages.

Retention campaigns get more relevant because the insights come straight from acquisition.

It’s all connected—brand, product, experience.

People don’t separate your ads from your brand; they are your brand.

Most agencies still stop at ROAS.They report spend, not signals.

And that’s the miss.

Ads aren’t just numbers on a dashboard—they’re customer truth in motion.

If you know how to read them, they’ll tell you everything you need to know about what to build next.


The real job isn’t delegation—it’s design

Stop outsourcing instinct.

Your team knows your customer better than anyone.

Your job as a founder isn’t to run the ads—it’s to build the system that runs without you.

Build a setup that flexes. Bring in partners for acceleration—not delegation.

That means building capability, tightening the loop between creative and finance, and owning your data.

Smart founders already get this.

They treat agencies like special ops—brought in for a single mission, not a forever role.

Test a new channel.

Scale creative.

Push innovation without losing control.

Everything else? You own it.


If I were your CMO

Here’s what I’d tell you before your next agency call:

Ask one thing—are they helping you own and optimize your marketing engine, or are they renting you theirs?

If they’re not showing up with insight, accountability, and strategy tied to your numbers, they’re not a partner. They’re a vendor.

Here’s what I’d look for:

1. Earned ad spend.

They should earn more budget by hitting CAC or CPO goals.

The bigger the spend, the smaller the % fee.

If that model doesn’t exist, ask why.

2. Measure on your terms.

Your data > their dashboards.

Track CAC, CAC:LTV, and Cost per New Customer—not ROAS slides.

3. Bring them in.

They should sit with your team. They should sit with creative not just marketing managers.

Show up ready with what’s working, what’s not, and what’s next.

4. Hire thinkers.

The people running your account matter more than the ones pitching it.

If your monthly ad spend’s six figures, you deserve senior operators.

5. Operators over order-takers.

They should talk retention, CAC, contribution margin, and compounding growth—not CTR.

If they can’t connect creative to cash flow, they’re not ready for your brand.


Marketing’s loud. Dashboards are pretty.

But most of it doesn’t move the needle.

Real growth is built, not bought.

You own your data, your brand, your customer, your results.

The rest? Rented attention.

That’s how you go from buying attention to building demand.
