What we do
Paid ads, email, and SMS retention run as one connected system, not two vendors pointing at each other. Here is how we drive full-funnel growth for ecommerce brands.

We run Meta, Google, TikTok, and programmatic for ecommerce brands that want profitable acquisition, sharper testing, and reporting you can act on. Built to scale what is working, not to guess.

We build and manage Klaviyo and Attentive programs that lift repeat purchase rate and lifetime value. Strategy, flows, campaigns, and list health, all aligned to the same growth plan as your ads.
Explore retention →
Ad and lifecycle creative built from what the data says is working, then iterated fast. More testing velocity, stronger conversion, and winners that keep compounding across channels.
Explore creative →
One source of truth across every channel. MER, CAC, and contribution margin reported plainly enough to run the business on, so budget decisions stop being a debate.

The brands we work with stay for years, not quarters. One team running acquisition and retention, and numbers the owner can feel. Here is what a few of them say.
“
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.
★★★★★
“
I've worked with CSG for nearly 5 years and they've played a major role in taking our business from ~$100K to $2MM per year. Collaborative, proactive, and incredibly reliable - a true growth partner.

How it works
A clear path from audit to ongoing optimization. Most clients are live within the first month, not 90 days in.
01
We look at your numbers before we say anything. Spend, margins, list health, and where growth is actually stuck.
02
A plan scoped to your revenue stage. Channels, budget, offers, and lifecycle mapped as one system, not two workstreams.
03
Tracking, accounts, flows, and creative live within the first month, not 90 days in. You keep every system we build.
04
Weekly tests, monthly strategy, and transparent reporting on MER and CAC. No surprises, no vanity dashboards.
Who we are
Coast Summit Growth is a full-funnel growth team for ecommerce brands that are done with fragmented execution. Most brands run acquisition with one vendor and retention with another, then spend the quarter refereeing.
We run both, out of San Diego, for DTC and ecommerce brands scaling from $300K to $5M+. One team, one strategy, one number that matters.


Our approach
You work with the senior strategist doing the work, not a junior handoff behind an account manager. No slow layers, no bloated reporting, and every system we build stays yours, even if we ever part ways.
Plans
Choose exactly what you need. No cookie-cutter packages, no locked-in retainers for work you are not using.
