Cut Your CAC by 20% in 90 Days. Without Increasing Ad Spend.
The Profitable Growth System is a full-funnel growth system built for DTC brands tired of watching CAC eat their margins. We plug in as your fractional head of growth and fix the system behind your acquisition — paid media, conversion, and retention — so every dollar works harder.
Every DTC brand hits the same wall, and it's not the wall they think.
You've built something real. Product-market fit. A paid media presence. A team that ships. But at some point, the economics stopped working in your favor and no single fix is making them work again.
CAC keeps rising. Margins keep shrinking.
You're not spending recklessly. You're spending exactly the way every agency told you to. More budget. More channels. More creative. But every new dollar costs more to recoup. Scaling feels like a treadmill that just goes faster.
You're paying to acquire customers who don't come back.
Half your CAC math should be retention working in the background. But it isn't. So every month you're paying full freight to replace customers you already won, but the unit economics never get better.
Your "fixes" aren't fixing it.
You've tried new creative. New audiences. A different agency. Better attribution. Some of it helped a little. None of it solved the real problem, because the real problem isn't any single channel.
Revenue grows. Profit doesn't.
The top line moves. The bottom line stays flat, or worse. Contribution margin is the number that doesn't lie, and it's been telling the same story for months.
The problem isn't your ads.
It's the system around them.
Most DTC brands run a collection of disconnected tactics: paid here, email there, retargeting somewhere else. Tactics without a system don't compound. They just cost money. The longer you operate without one, the more expensive it gets to build one later.
The Profitable Growth System
A complete growth system built for one outcome: profit. Three integrated pillars. One result: lower CAC, higher LTV, and growth that compounds month over month.
Acquire
Paid acquisition that knows exactly who to target, what to say, and what it should cost to bring them in.
- Multi-platform paid acquisition (Meta, Google, YouTube, TikTok)
- Creative testing system that fights creative fatigue before it hits performance
- Audience and angle optimization tied to ICP and purchase intent
- CAC benchmarks per channel so every dollar has a target to beat
The Outcome: A paid acquisition engine that knows exactly who to target, what to say, and what it should cost to bring them in.
Convert
Higher revenue per visitor, turning the traffic you're already paying for into more customers.
- Landing page and PDP audits to identify friction and conversion gaps
- Offer architecture: pricing, bundles, AOV optimization, guarantees
- Systematic A/B testing on creative, copy, and conversion experiences
- Funnel-stage CAC tracking so you always know what's working
The Outcome: Higher conversion rates across the board, without spending more to get them.
Monetize
Customers who buy more, buy again, and refer others. Driving LTV growth that makes your CAC numbers work harder over time.
- Lifecycle email + SMS systems engineered for repeat behavior
- Post-purchase flows that increase second-order rate
- Segmentation and win-back campaigns that re-activate lapsed customers
- Loyalty frameworks that reward high-LTV cohorts
The Outcome: Customers who buy more, buy again, and refer others. Driving LTV growth that makes your CAC numbers look better and better over time.
What separates a vendor from a partner
Plus a fractional head of growth embedded in your business.
Most agencies optimize their channel and call it a day. We optimize the entire growth equation, and we're accountable to the same number you are.

What Our Satisfied Customers Are Saying About Us
"We couldn't recommend him more"
Palm has been working with Coast Summit Growth for several years now. While the decision at first was motivated by budget, the sustained relationship has been for the diligence and reliability of detailed information, strategy and implementation helping us navigate the incredibly difficult but necessary ecosystem of paid media that we rely on so much.
Carlos has always been deeply passionate about performance and growth for our business as though he’s part of our team not just an extension of it. We couldn’t recommend him more.
Joe Ciafardoni
Co-Founder at Palm Golf Co.
"Our sales doubled, and we didn't add a dollar to our budget"
When we brought Coast Summit Growth on, we were leaning too hard on the wholesale channels and our own website was underperforming. They came in, cleaned up our email list, built smarter campaigns, and the results spoke for themselves. Our daily and weekly sales on AtlasTickets.com doubled, and we didn't add a dollar to our ad budget to get there. Open rates climbed 44%, click rates doubled, and our bounce rate went from 50% to under 1%.
After 37 years in this business, I've worked with plenty of marketing folks. CSG is the real deal.
Vince Martinico
Partner at Atlas Tickets
"He approached [our growth] like a partner, not a vendor"
RWTP Supply Co. came to Coast Summit Growth as a small brand just getting its footing in paid media. We needed someone who could not only build our Meta campaigns from scratch but also help us understand the strategy behind them.
They showed genuine investment in our growth by walking us through budget strategy, optimization priorities, and the necessary prerequisites for maximizing ad performance. He approached it like a partner, not a vendor. For any brand navigating the complexity of paid social, we'd point them to Coast Summit without hesitation.
Cooper Lopez
Founder at RWTP Supply Co.
We Work With DTC Brands at a Specific Stage
The Profitable Growth System isn't for everyone. It's built for brands where the system can actually perform.
Revenue: $2M–$20M
Established DTC brands with proven product-market fit and a real customer base worth scaling. You've figured out what sells, now it's about scaling profitably.
Ad Spend: $20k+ Monthly
You're serious about paid acquisition and have the budget to build a real system, not test a theory. Paid media is already part of your growth strategy; we make it perform better.
Goal: Scale Profitably
Not just revenue growth: profitable growth, with strong unit economics and sustainable contribution margin. You're done celebrating revenue that costs more than it makes.
Behind the system
Built by operators who've scaled both sides of the equation.
Coast Summit Growth was founded on a simple insight: most DTC brands don't have a CAC problem or an LTV problem; they have a system problem. The team behind the Profitable Growth System has spent over 15 years proving exactly that.
On the lifecycle side: 7+ years building retention engines at scale, including owning the lifecycle program at GOVX, a $10M ecommerce marketplace with hundreds of thousands of customers on its email list. That's the kind of operational depth most agencies don't have access to, as it exists only in operators who've actually run the systems in-house.
On the acquisition side: $100M+ in paid media managed across dozens of DTC brands: apparel, CPG, fintech, pet food, online auctions, home goods, golf. The anchor proof point is Palm Golf Co, where our founder led the program that grew them from $100K to $2M in revenue. Same product. Same category. The difference was the system.
Coast Summit Growth exists to bring both of those disciplines together so DTC brands can stop optimizing channels and start optimizing economics.
Selected results across $100M+ in paid media managed and 7+ years of lifecycle program ownership. Includes work led during prior agency tenures (2015–2024) and at Coast Summit Growth.
Selected wins—when the system fixed the math.

Monthly retainer
The Profitable Growth System
Starting at $6K/mo
Full execution across all three pillars — paid media, conversion, lifecycle — plus the strategic layer (fractional head of growth, weekly syncs, CAC:LTV reporting).
Most engagements run $6K–$10K/month based on scope and ad spend. Pricing reflects the full system, not à la carte.
The cost of waiting isn't zero
Every Month Without a System Is a Month You're Paying for It.
The DTC brands that build a real growth system now are the ones with the data advantage, the retention flywheel, and the CAC efficiency 12 months from now.
The ones that wait are spending those same 12 months paying to acquire customers they won't keep, running campaigns that don't compound, and watching contribution margin stay flat while revenue grows.
There's no neutral position here. The absence of a system has a cost; it just shows up on a different line of your P&L.
❌ Ad spend that generates less than it should
❌ Customers who buy once and don't come back
❌ Competitors building the infrastructure you don't have yet
❌ 12 months of learning you could have had behind you

We're selective about who we take on. Not just because capacity limits it, but because we only partner with brands where we're genuinely confident the Profitable Growth System will perform.
You might be wondering...
Frequently Asked Questions
We've tried paid ads before and it didn't work. Why is this different?
The channel is rarely the problem, it's the system around it. Most failed paid programs lack the right creative strategy, the right conversion layer underneath them, and the retention infrastructure to make the long-term math work. We don't just run ads. We build the complete front-end and back-end system that makes paid acquisition profitable at scale.
How is this different from every other agency saying the same thing?
Most agencies optimize a channel — paid, email, creative — and report on that channel's metrics. We optimize the system that drives growth economics across all of them. The difference shows up in the math: agencies tell you "ROAS improved 15%." We focus on things like "CAC dropped 18%, LTV climbed 14%, and contribution margin moved from 32% to 41%."
We don't have the bandwidth to onboard another partner.
That's exactly why partners exist. We embed as your fractional head of growth; meaning we're doing the work, not adding to your to-do list. Onboarding takes 60-90 minutes of your time across the first two weeks. After that, you show up to a weekly sync and approve direction.
We've tried lifecycle and email before... it didn't move the needle.
Most "tried lifecycle" actually means a welcome flow and an abandoned cart. That's the bare minimum, not lifecycle. Real lifecycle is segmentation, post-purchase, win-backs, replenishment, and behavioral triggers. Coordinated as a system, tied to LTV cohorts. That's the version we build.
What's the minimum ad spend required to work with you?
We work with brands running $20K+ in monthly paid media. Below that threshold, the full system - acquisition, conversion, and retention working together - doesn't have the volume to compound the way it needs to. If you're not there yet, we'll tell you honestly and point you in the right direction.
What if our CAC is already pretty efficient?
Then we'd lead with LTV, not CAC. The Profitable Growth System doesn't force a CAC reduction onto a brand that's already efficient there. It works on whichever side of the equation has the most leverage. The audit identifies which.
What's the contract length?
Three months initially, then monthly thereafter. The changes we make to implement and optimize the Profitable Growth System require time for the results to kick in. If we're not delivering after the first 90 days, you don't owe us until we deliver efficiency improvements.
Schedule time below to see exactly how The Profitable Growth System can work for your business.
Most DTC brands at your stage are sitting on more profit than they realize, it just needs the right system to unlock it.
The Profitable Growth System is how we do it. We plug in as your dedicated growth partner and build the three things that drive predictable, profitable scale: a paid acquisition engine that lowers CAC, a conversion system that turns traffic into buyers, and lifecycle marketing that grows customer LTV over time.
More profit. Stronger margins. Less on your plate.
