Ecommerce Playbook: Numbers, Struggles & Growth

Most 7-figure brands are stuck in the same loop. They've outgrown guesswork but can't justify a $15K/month agency retainer. Every dollar has to work, and there's no infrastructure to know if it is.

Joy Sharma breaks down how the Prophit Engine system adapts for brands in the 7-figure range.

What this episode covers:

• Why "just use AI" doesn't replace the PE - the difference between general advice and accountability backed by 12 years of data

• The 3 core services: forecasting, strategy, execution - all in one operator

• Why creative strategy lives inside the PE (and why that's controversial)

• The "ruthlessness of the forecast" - how modeling drives every decision

• Creative scoring: why making more ads doesn't help if they all look the same to Meta

• How the growth strategist connects creative to the marketing calendar, not just to ROAS

• Units of growth: marketing calendar, creative, landing pages, offers

The Prophit Engine 7 uses the same methodology, same data models, and same system as the full PE8 - calibrated for the stage your brand is at.

The PE doesn't replace your internal team. It gives them the infrastructure they've been missing.

Every brand wants more capacity from their growth team. Most try to solve it by adding people or plugging data into ChatGPT. Neither works.

In this episode, Luke breaks down the 3-layer infrastructure behind the Prophit Engine that actually creates capacity:

Layer 1: The Database

Order-level, finance, marketing, and cost data aggregated in one place. Living in the context of your targets and forecast, not just historical performance. Informed by a data set across hundreds of brands and billions in GMV.

Layer 2: Methodology & Context

The layer most people skip. Drop a Statlas dashboard screenshot into an LLM with no context and you get useless output. Layer in CTC's hierarchy of metrics, outlier methodology, and 12 years of pattern recognition across the DTC landscape and the output transforms completely.

Layer 3: The Tech-Enabled Operator

The Prophit Engineer sits on top of both layers. Not just a person with a dashboard. A person with aggregated data, informed methodology, and AI tooling that multiplies their capacity to make decisions and execute in real time.

This is why one Prophit Engineer outperforms a traditional 4-person growth team. The infrastructure does the heavy lifting. The operator makes the decisions.

Most brands have a media buyer, a strategist, and a creative lead. Everyone's doing their job. Everyone has a dashboard. But when you ask "are we on plan this week?" you get three different answers.

In the episode Luke breaks down the three pillars of accountability inside the Prophit Engine:

1. We create the forecast AND execute against it. No handoffs between planning and doing.

2. One person owns the entire workflow. Every lever is at their disposal, from media mix to creative strategy to Meta campaign builds.

3. Skin in the game. Our compensation is tied directly to hitting your contribution margin target.

This isn't about adding more people. It's about collapsing the workflow into one operator with the full picture, backed by infrastructure that handle

Most ecommerce brands are making slower, worse decisions than they realize, and it's not because of bad people. It's because of a broken structure.

In this episode, Richard sits down with Luke and Tony to break down one of the most important benefits of the Prophit Engine: total clarity. From fragmented data and siloed teams to a single operator with a full end-to-end view of the business, they unpack exactly why consolidation leads to better decisions, faster action, and stronger results.

They also walk through a real-world sale that crushed projections, and explain why having three people with three partial views of the same problem is often worse than having one person with the complete picture.

In this episode:

• Why siloed teams lead to degraded decision making

• The 3 layers of clarity the Prophit Engine provides

• How a single operator outperformed a multi-person workflow over a live sale weekend

• Why your Meta media buyer needs to understand your inventory position

• What the biggest ecommerce opportunity looks like in 2026

The litmus test: How much of your weekly marketing meeting is spent figuring out what's going on — versus actually making decisions to change it?

If most of your time is in the first bucket, this episode is for you.

What if one person could replace your entire ecommerce growth team, and get better results? In this episode Richard and Luke break down exactly how the Profit Engine works and why it's changing the way DTC brands scale.

Luke walks through the four core functions every ecommerce brand needs — forecasting & target setting, creative strategy, media measurement, and Meta media buying — and explains how one person, enabled by the right tools and data models, can own all four. The result? A leaner, faster, more profitable growth operation.

What we cover:

• What the Profit Engineer role is and why it exists

• The 4 data models powering the forecasting system (Spending Power, Retention, Event Effect & Creative Demand)

• How to build a daily forecast accurate to within 3% of target

• How the Ad Plan determines exactly how much creative you need and who should make it

• How Media Mix Modeling (MMM) and geo holdout incrementality testing optimize budget allocation across channels

• How the "Push to Build" feature launches Meta ads in seconds instead of hours

• Why reducing time from insight to action is the real unlock for ecommerce growth

Everything you need to understand the Profit Engine system — from the data models to the media buying — is in this episode.

Common Thread Collective just launched the Prophit Engine to the public—and in this episode, Richard and Taylor break down what it is, why it exists, and how it helps DTC brands forecast more accurately, grow contribution margin, and simplify their growth stack for less cost. 

You’ll hear how CTC is combining data + methodology + AI-enabled tooling into a system (and a new “Profit Engineer” role) that replaces complexity with clear expectations and execution.

What we cover

• Why profit + predictability are harder than ever for DTC

• What the Prophit Engine is and the outcomes it’s built to deliver

• How the Profit Engineer role collapses growth strategy, Meta buying, and creative strategy into one operator

• What brands still own vs. what CTC takes off the plate—and who this works best for

In short: this episode introduces CTC’s Prophit Engine as a tech-enabled operating system for growth—built to replace a fragmented stack of people + tools with one clear forecast, tighter execution, and accountability to contribution margin. If you’re trying to run leaner without sacrificing performance, this is the blueprint for how CTC thinks the next era of agency services will work.

In this episode, Richard and Taylor Holiday discuss the rise of the “SEANs” — the Software-Enabled AgeNcy — and why it represents a fundamental shift in how eCommerce brands will build growth teams going forward.

Taylor explains how traditional agencies struggle to operationalize institutional knowledge across individuals, leading to inconsistent execution and diffused accountability. The solution? Embedding a clear point of view directly into software, turning ideology into infrastructure. Rather than offering neutral tools like Ads Manager, CTC is building software with an opinion: a system designed to unify marketing and finance around a daily, trackable path to predictable, profitable growth.

The conversation explores:

• Why “software with a point of view” is different from open-ended tools

• How declining SaaS gross margins and rising customer demands for outcomes are collapsing the line between software and services

• Why agencies are becoming more like software companies — and software companies more like agencies

• The impact of AI on compressing labor costs and increasing individual output expectations

If you care about the future of growth teams, SaaS economics, and how AI is reshaping both labor and leverage inside eCommerce, this conversation is a must-listen.

Incrementality tests are “in”… but the real problem is what you do after the read.

In this episode, Taylor sits down with Olivia Kory (Chief Strategy Officer at Haus) and George Davis (CMO at Cozy Earth) to unpack the messiest part of modern measurement: operationalizing incrementality when results swing, channels conflict, and “platform ROAS” can’t be trusted.

If you’ve ever asked:

• “Our holdout came back way lower than Meta… now what?”

• “Why don’t test results replicate month-to-month?”

• “How do I actually use an incrementality factor in real budget decisions?”

• “If everything is under 1.0 iROAS… should we cut spend or keep investing?”

…this one is for you.

What we cover

• Why incrementality requires a holdout (and why “spend up / spend down” isn’t enough)

• The replication problem: why results change even with “clean” tests

• The gap between measurement and optimization (platforms optimize for attribution, not incrementality)

• How operators use incrementality factors without letting them become a blunt instrument

• Why channel vs. channel is often the wrong fight (and why profit thresholds matter more)

• iROAS → IMR (Incremental Marginal Return): a more intuitive way to compare performance

• Budget cadence: daily realities vs monthly allocation decisions

• Long-term effects, “adstock” claims, and why post-treatment windows matter

• Practical levers that can improve results: creative, account structure, exclusions, distribution expansion (Amazon/retail)

Sales tax feels simple—until you hit nexus.

In this episode, Ryan Pinkham (VP of Go-to-Market at TaxCloud) breaks down why sales tax gets complex fast for growing ecommerce brands, what happens when you cross nexus thresholds in new states, and how ignoring compliance can turn into a painful (and expensive) distraction.

We cover:

• What sales tax nexus actually means for ecommerce

• The three “buckets” of brands (doing nothing, unhappy with current tools, or knowingly delaying)

• Why sales tax is a year-round operational load

• How modern brands approach checkout tax vs. filing/registration

• The Streamlined Sales Tax (SST) program and why 24 states matter

• A simple start-of-year checklist to get compliant and reduce risk

If you had a strong Q4 and expanded into new states, this is your sign to do a quick nexus and tooling review..

Acquisition is getting tighter! In this episode, we flip the script and talk about the lever most brands under-invest in: retention + lifecycle marketing.

Taylor is joined by Jennifer Peters, Director of DTC, MarTech & Digital Compliance at OLLY (a Unilever brand), to break down how they think about keeping customers coming back when the brand is sold everywhere — from Target and Walmart to their own DTC site.

We get into what retention really means beyond “subscription,” how to message customers when you don’t want to channel-shift them, and how OLLY is using loyalty (including receipt scanning) to better understand in-store shoppers.

What you’ll learn:

• How OLLY drives retention across DTC + retail

• Email vs SMS strategy, plus segmentation that prevents “list blasting”

• Using loyalty + receipt scanning to understand in-store shoppers

• Setting smarter KPIs for promos, launches, and content

• Why they chose Attentive, how they handled ESP migration, and where AI actually helps

• The first retention moves: audit flows, refresh creative, nail the basics

If you’re running ecommerce for a consumable, CPG, or multi-channel brand, this is a must-watch for building a retention engine that actually scales.
