Hey there,
If you're already growing successfully (like spending at least $50K–$100K+/month on ads) and you've tested creative, audiences, and offers, but CAC is still stuck or creeping up, you're probably not dealing with an "ad problem."
You're dealing with a growth system problem.
Most of the time, the real constraints live in:
- Unit economics & pricing
- Positioning and offer structure
- Conversion funnel / onboarding
- Retention and payback dynamics
- Product–channel fit
The problem is that most agencies are structurally set up only to touch the ad layer.
Their scope of work covers targeting, bidding, and creative. So when CAC is off, they do the only thing they're scoped (and staffed) to do:
"Let's launch more creative, tweak bids, and try new audiences."
The issue isn't incompetence; it's misalignment. Their job ends at the ad click—they can't fix what happens after someone lands on your site or find deeper foundational issues.
How we approach it at Demand Curve
Using a simple example:
You're spending $120K/month on Meta and Google.
Your CAC target is $180. Actual CAC is $260.
Leadership wants you back to $180. They love the volume at the higher CAC, but the unit economics aren't sustainable.
A typical agency says:
"We'll bring CAC down by testing new angles and creative. Give us 90 days."
We start by asking a different set of questions:
- How much more leverage is created by reducing CAC vs. focusing on engineering the conditions to make the $260 sustainable?
- Where in the funnel is value leaking? (LP → signup → activation → retention)
- Is your packaging/offer forcing you into a too-tight CAC target?
Then we map the system:
- Diagnose the constraints (pricing, funnel, product–channel fit, retention).
- Fix what blocks paid from working—sometimes that's funnel changes, sometimes offer/positioning, sometimes activation and retention mechanics.
- Then scale the channels with senior operators who know how to push spend responsibly.
Ads are still part of the solution. They're just not the only lever we know how to pull.
Why we're able to do this when others don't
Two reasons:
- We've trained thousands of founders and growth teams through the Demand Curve Growth Program. The frameworks we teach there are the same ones we use with agency clients.
- No bait-and-switch. Most agencies claim to be a "strategic partner." But once you're a client, they pass you on to a team of juniors running a fixed playbook. With us, you're working with a strategist with 12-15+ years of experience. We don't employ juniors on the agency side.
What working with us looks like
- System-level audit first: economics, funnel, and channel fit before we promise scale.
- Dedicated senior strategist + media buyers + creative support: no junior team handoff.
- Funnel & LP optimization included: we don't ignore the pages your traffic lands on.
- Lean, async communication: no vanity decks; we'd rather spend time moving your numbers.
- Engagement structured around scale, not hours: we offer a mix of retainer- and performanced-based options.
Meet your team lead
Prash Brooks is a Senior Strategist with 15 years of scaling paid acquisition. A bit of a unicorn in the growth marketing world as he's been on the agency, brand, and platform side (he's seen how the system was built during his time at Meta).
He's not an account manager. He's not delegating the actual work to juniors. He's the operator who will be in your ad accounts, building your strategy, and accountable for moving your numbers. He becomes a part of your team.
A few examples of his work
- Videogen – 10x scale while maintaining CAC targets
- Plankk – Reduced CAC by 21% in less than 3 months
- AgelessRX – Increased monthly media spend by 147% whilst maintaining CAC
If you're already investing heavily in paid and feel like you've hit the ceiling of what optimization alone can do, we should talk.
We'll be honest if the constraint isn't something we can meaningfully move—and we only take on clients where we believe we can.
