Ecommerce Playbook: Numbers, Struggles & Growth

Joy Sharma runs CTC's PE7 program for mid to high 7-figure brands. His claim: if you're stuck at a growth plateau, he can diagnose what's wrong without looking at your ad account. The answer is almost never creative. It's almost never ad structure. It's offer-market fit.
In this episode, Joy breaks down why Facebook's auction works against you as you scale spend, how the AOV-to-CAC ratio determines your ceiling, and why Q3 is the single most important window for 7-figure brands to get this right before Q4.
In this episode:
Why growth plateaus are a business problem, not a marketing problem

How Facebook's auction gets harder as you spend more

The AOV vs. CAC framework that reveals who you're actually competing against

Why Q3 is the window to solve offer-market fit before Q4 spend ramps

How CTC's Marketing Moments service guarantees incremental revenue

The sequence that matters: product-market fit → offer-market fit → creative strategy

Key insight: Creative strategy is a volume mechanism, not an efficiency mechanism. If you're trying to solve a business problem with a marketing solution, that's where 7-figure brands go to die.

Meta has fundamentally changed how it targets and delivers ads, and most brands are still operating on the old rules. In this episode, CTC's VP of Paid Media Tony Chopp breaks down the CTC Methodology for Meta advertising: why creative is now the targeting, how Meta's Andromeda and GEM systems make decisions no human operator can match, and the counterintuitive principle that defines how our profit engineers manage accounts every single day.
Topics covered:
How Andromeda and GEM replaced audience-first targeting

The breakdown effect and why historical ROAS doesn't predict future ROAS

Campaign structure: evergreen vs. marketing moment campaigns

Signal quality, CAPI integration, and event match quality scores

Budget liquidity and why day-to-day spend variance is a feature, not a bug

The four-phase framework for solving underspend

Why turning off ads is the single most common mistake brands make

Key stat: Meta's Andromeda enables a 10,000x increase in model capacity per impression opportunity.

Your platform ROAS is not the truth. It's a story your attribution tool tells you. Luke Austin, breaks down exactly how CTC approaches marketing measurement — and why the gap between platform-reported numbers and actual incremental revenue is where most brands make their worst capital allocation decisions.
This is Part 3 of the CTC Canon Series — our codified methodology across the core disciplines of ecommerce growth. In this episode, Luke covers the full measurement framework: why geo holdout tests are the gold standard, how CTC's database of hundreds of incrementality tests gives every new brand a head start, and what it means to build "progressive truth" over time instead of chasing a single source of truth.
Topics covered:
Why media efficacy is always in flux — and why any system that treats it as fixed is lying to you

The measurement gap: reality vs. fiction, and how to move closer over time

Geo holdout tests explained — how they work, why they're the gold standard

CTC's incrementality benchmarks by channel: Facebook acquisition (1.14x iROAS), Google Branded (0.27x iROAS), and more

Why Google branded search dramatically over-reports ROAS

How iROAS normalization enables true apples-to-apples channel comparison

The three-stage framework: aggregate benchmark, individual test, accumulated median

Why iROAS is always subordinate to contribution margin

Most brands forecast from gut feel and ROAS. CTC runs on four interlocked proprietary models that produce a daily P&L forecast with 3.1% accuracy across more than $3 billion in GMV. In Part 2 of the Canon series, Luke Austin breaks down each model, how they connect, and what a Profit Engineer actually does with them
Topics covered:
Why a single ROAS number can't run a business

The Spending Power Model — ACoNS curves and what spending power actually tells you

The Retention Model — forecasting returning revenue cohort by cohort

The Event Effect Model — how to get daily precision without breaking monthly targets

The Creative Demand Model (teased — full breakdown in the creative strategy episode)

How these four models wire together into a connected forecast system

What R-squared below 0.6 signals about your retention data

The three optimization points every brand should know: max CM, max revenue, max LTV CM

Key stat: 3.1% forecast accuracy across $3B+ in GMV managed — producing 30%+ revenue growth and 40%+ contribution margin growth.

Every dollar spent on SaaS is a dollar that does not go into ads.
In this episode, Luke Austin sits down with Gil Dyen, Head of Marketing at Rutsu Barefoot, to walk through a real email and SMS platform migration to Omnisend — what drove the decision, what the process actually looked like, and how a 60,000-contact list got fully migrated in under 30 days with less than a working day of direct involvement.
Gil runs marketing at a mid-7-figure DTC footwear brand that has sold 45,000 units in its first 18 months, with a clear mandate: keep SaaS costs lean, reinvest every freed dollar into Meta spend and creative, and build the retention engine that takes the brand from 12% returning customers today to 45% by year three.
Topics covered in this episode:
Why a bootstrapped DTC brand audits its SaaS stack constantly

The two criteria that actually drive platform decisions: cost and time

How Omnisend managed the full migration, from contact database to flow automations

What the QA process looks like after a migration (and how long it takes)

The warm-up mechanics: 9 days to re-engage 60,000 contacts

Why Q4 is the wrong time to switch email platforms (and when to do it instead)

How an ESP migration becomes a flow audit opportunity

CTC's Omnisend integration inside Statlas for forecast-connected email tracking
