An ecommerce growth partner who treats your store like their own.
Performance marketing for DTC, retail, and marketplace brands. Meta, Google, TikTok, Pinterest, Shopify CRO, and lifecycle email built around your real unit economics, not a generic playbook.
Book Intro →Ecommerce marketing is unit economics with extra steps
Every decent ecommerce brand eventually faces the same wall: paid CAC climbs until it hits your first-purchase margin, and now you can't scale without either cutting margin, expanding LTV, or finding a channel mix that actually works. Most brands try to solve this at the ad-account level. That almost never works.
The brands that break through are the ones that treat paid media, CRO, email, and retention as one connected system. A 3% bump in PDP conversion rate changes what you can afford to bid on Meta. A stronger post-purchase email flow adds $18 of LTV, which changes your break-even CAC, which changes everything downstream. The agencies that operate in silos can't pull those levers together.
At Noble Growth, one person - Mattimore Cronin - runs the whole picture. Coast Sports grew revenue 153% in one year under this model. EVCS cut CPA by 95%. The case studies are specific. The unit economics are real.

LTV and cohort tracking
What's your 90-day LTV? Your 12-month? Your repeat-buyer rate? We track cohorts and use them to justify CAC targets that let you scale.
How Noble Growth runs ecommerce growth
Onboarding week focuses on the economic picture: AOV, gross margin, shipping cost, first-purchase contribution, 90-day LTV, repeat-purchase rate, and SKU-level margin variation. This is the math that determines what a good CAC looks like and where the biggest leverage points are. Most ecommerce agencies skip this step and optimize to platform-level ROAS instead, which leads to the "profitable on paper, broke in real life" problem.
Weeks 2-4 are diagnostic across channels. Meta architecture, Google account structure, Shopify conversion rate benchmarks by device and source, email flow coverage, SMS consent rates, pixel health. We produce a ranked list of leverage points and attack the top 3-5 first.
From month two onwards, it's iteration. Creative tests on Meta and TikTok, feed optimization on Google Shopping, split tests on PDPs, subject line tests on email campaigns. One connected system, one scoreboard, one senior practitioner on the account every week.

Who this is best for
Noble Growth's ecommerce work is right for brands that:
- Do $500k-$20M in annual revenue with ambitions to scale to the next tier
- Have product-market fit (you're generating sales, just not enough or not profitably)
- Sell physical products with at least 50% gross margin or a clear repeat-purchase story
- Have a founder who will still weigh in on positioning, offer, and creative direction
Less ideal for: brands with total monthly ad budgets under $5k (the architecture work doesn't pay back), dropshipping operations with unsustainable margins, or businesses that need a full agency team of 8+ people across specialists (that's a different agency).
One flat monthly retainer. Every channel included.
No hidden fees, no percentage-of-spend markup, no long-term contracts. Month to month with 30-day cancellation.
Less than most agencies charge for a single channel. We share the number on the intro call.

What ecommerce platforms do you work with?
Primarily Shopify and Shopify Plus - that's where 80% of our ecommerce clients run. We also work with BigCommerce, WooCommerce, Magento, and custom stacks when needed. For marketplaces (Amazon, Walmart, Etsy), we typically coordinate with specialist partners rather than running marketplace ads directly - Amazon PPC, for instance, is a different craft and we're honest about the handoff.
How is Noble Growth different from specialist ecommerce agencies?
Most ecommerce agencies either specialize deep in one channel (Meta shop, Google shop, Klaviyo shop) or run a generalist model with a team of 6-10 people behind the scenes. Noble Growth is different: one senior practitioner runs every channel for every account. The coordination between paid, CRO, and email - the piece that usually lives in handoff emails - is internal to one brain. That's the entire operating advantage.
What's your approach to creator and UGC content?
For most DTC brands, creator content now outperforms produced brand video on paid social. We handle briefing, creator sourcing from our network, whitelisting setup, and content rights. See Why UGC Ads Outperform for our full philosophy. Budget: typically $500-$2,000 per creator piece, 3-8 pieces per quarter for most clients.
Do you manage Amazon or marketplace ads?
Not primarily - we focus on owned-channel acquisition (Meta, Google, TikTok, email). For Amazon PPC and marketplace optimization, we usually recommend a specialist partner or run the marketplace separately from the owned-store growth system. We can coordinate the two but we won't pretend to be experts at something we don't run every day.
Can you help us model LTV and build a cohort view?
Yes. For any client doing $1M+/yr, we build a cohort-based LTV model in the first month: what's the 30-day, 90-day, 12-month LTV by acquisition channel? What's the repeat-purchase rate? Which SKUs drive the highest LTV on first purchase? This math determines what CAC you can sustain, which determines what campaigns you can profitably scale.
What about international expansion?
We've launched and scaled brands into UK, AU, CA, and parts of EU. The playbook is: replicate the paid mix, localize landing pages and email, set up per-region pixel and conversion tracking, and run a 90-day ramp with conservative CAC targets until data matures. Shopify Markets makes the back-end logistics manageable for most brands.
