Growth Case Studies

Proof Brand + Performance Drives More Profit Than “Performance” Alone

These case studies show the full system in practice: brand media, paid media, creative, CRO/web merchandising, retention, LTV analytics, planning, and Marathon Data measurement. The proof is contribution dollars, scalable demand, and operator-led growth from the Chubbies founders and operators who built the brand past $100M/year, lived the direct-response plateau, made the hard brand transition, and came out the other side through a nine-figure exit.

Brand + Performance Drives More Profit in the Long Term AND the Short Term

Contribution margin (total revenue − product costs − ad spend) measures the dollars your business actually keeps. It’s the clearest measure of whether growth is profitable — and it’s how we hold ourselves accountable. A media mix can look worse in platform ROAS and still be better for the business if it creates more incremental contribution dollars.

We're Operators, Not Theorists

  • We built Chubbies past $100M/year and through a nine-figure exit, so the work is grounded in founder/operator reality
  • We lived the soft months, board questions, false starts, and attribution fights that make most brands abandon brand investment too early
  • Losing money for six months while waiting for brand to “kick in” is not a luxury any business owner has
  • In every case where we’ve taken over, we’ve seen immediate improvement — not loss
  • We start conservatively and expand as results confirm

Better Allocation, Not Added Budget

  • Reallocate the least efficient dollars first — no additional budget required
  • Orient spend toward incremental new customer growth
  • Contribution dollars and margin growth have improved within the first month across our clients

Brand IS Better Performance

  • These results come from a proprietary brand-building playbook — not traditional direct response
  • Brand campaigns drive stronger incremental ROAS than anything on the DR side
  • Brand + performance can create more profit even when the platform dashboard reports lower ROAS
  • Marathon’s measurement infrastructure captures brand impact in real time — not quarterly. Every campaign is optimized continuously, which is why the results are both large and repeatable
  • The data below proves it across media, merchandising, CRO, retail, and wholesale outcomes

Profitable Growth, Proven — Not Promised

Across the portfolio, Marathon grows the business on the metric that matters — contribution dollars and incrementality — not vanity ROAS.

We do CRO, too — and it compounds into the P&L.

Beyond media, Marathon runs a continuous, structured on-site testing program — and only validated winners ship to 100% of traffic. It’s the most under-rated lever in growth, and it compounds harder than any paid-media incrementality test: an incrementality test measures the return on one channel’s spend, while a CRO win lifts the value of every session — paid or organic — permanently, right at the bottom of the funnel where intent is highest. A single win keeps paying across all traffic, from every channel, long after the test ends — and the downside is capped: a test that doesn’t graduate never ships and costs nothing but a sharper read on what does.

Are these numbers good?

Measured brand advertising can drive more profitable growth than direct response — and the gains show up quickly, in the number that matters most: contribution dollars.

Brand Drives More Revenue Than DR

1.93x – 2.39x iROAS on Brand Campaigns

Brand outperformed the direct-response tactics tested in the same accounts, in the same windows. Measured by rigorous causal geo-holdouts — 90% confidence interval lower bound above 1.0x on one test; 97% probability of positive return on the other. The platform dashboard made the brand mix look less efficient. The actual business result was more incremental profit.

No Trough, Immediate Profit

Contribution Dollars Rose From Month One

The industry says brand investment means months of losses before any payoff. The data says otherwise. In the engagements we’ve measured, contribution dollars and margin improved within the first month — no trough, no observed revenue drop. We reallocate the least-efficient spend first, so the profit shows up immediately while the business keeps growing.

Why these results are so important: Measured brand advertising can drive more profitable growth than direct response — and it shows up fast. Same accounts, same windows, brand outperformed the DR tactics tested, and contribution dollars rose from the first month with no trough. Direct response stops when the ads stop. Brand compounds. The hard part is proving when a lower platform ROAS is actually the more profitable choice, then helping the leadership team keep acting while the old dashboard objects. That is the founder-level playbook Marathon Engine was built to run.

Results at a Glance — by Brand

The results below come from work Marathon Engine actually runs when the DTC dashboard stops explaining the whole business: paid media, brand campaigns, CRO/web merchandising, retention and LTV strategy, analytics, growth planning, and Marathon Data measurement.

Incremental Returns & Web Revenue

Beauty & Skincare (~$100M)

2.39x

97% confidence across Shopify, Amazon, and TikTok Shop. Brand beat every DR tactic tested in the same account, in the same window.

Outdoor Gear (Wholesale)

2.5x

Causal holdout at a major retailer proves brand building materially drives wholesale. 2.5x incremental retail partner revenue lift on brand media alone.

~$40M Food & Bev

1.93x

6-month causal geo-holdout. 90% CI: 1.45x–2.41x, 2.1x higher than blended DR ROAS, with brick-and-mortar lift 2x larger than e-commerce.

Modern Consumer Brand

~$2M Annualized

Nearly $2M in annualized incremental revenue in the first months from web merchandising and CRO work powered by Marathon Data.

Operating Leverage

Core Lever

Revenue Per Session

A 10% lift in revenue per session improves revenue and direct response economics without changing the media tactics.

Team Model

Senior Operators

Founder-level strategy and seasoned brand operators stay close to the work: creative, media, CRO, retention, measurement, analytics, and business decisions.

Operating System

Marathon Data

GA4, Shopify product economics, COGS, retention cohorts, and LTV data inform which tests matter, how to prioritize them, and when to scale.

What We Heard From the Industry — and What the Data Actually Shows

What the Industry Says

  • Brand investment means adding budget on top of what you’re already spending
  • There will be months of losses before any payoff materializes — it’s a long-term play
  • Performance media means direct response — top-of-funnel doesn’t drive measurable returns
  • No one has proven this works at scale — results like these are a one-off that cannot be replicated

What the Data Actually Shows

  • Top-of-funnel brand campaigns drive stronger incremental ROAS than direct response — proven across multiple brands by rigorous causal holdout tests
  • Reported platform ROAS can fall while contribution margin, new customer demand, and total profit rise
  • Contribution margin improves in weeks because the least efficient DR dollars are reallocated first — no budget added
  • Brand searches, new customer acquisition, and community growth respond in days and weeks, not months
  • The results have been replicated across multiple brands, categories, and channels — it is not a one-off

Every incrementality result below was measured by direct response standards — the hardest standard there is. The brand perspective upside is additive: while driving incremental revenue, these campaigns simultaneously build audience, brand searches, and baseline. A 2x return on brand spend is fundamentally more valuable than a 2x return on DR spend — the brand version compounds. That is why Marathon Engine is brand-building first, not ROAS-first.

Modern Consumer Brand · Web Merchandising + CRO · First Months

Nearly $2M in Annualized Incremental Revenue from Web Merch & CRO

Marathon Engine treated web merchandising and CRO like a growth function, not an e-commerce backlog. The work was powered by Marathon Data web merchandising analysis and a decade-and-a-half of operator experience knowing which tests are most likely to move revenue.

Annualized Lift

~$2M

Nearly $2M in annualized incremental revenue from the first months of the engagement.

Timeline

4 Months

Structured test selection, implementation, and monitoring produced early measurable lift.

Core Metric

RPS

Revenue per session became the operating lever, not a buried e-commerce metric.

Why It Worked

  • Marathon Data exposed where site behavior, product economics, and traffic quality were misaligned
  • The team prioritized the tests most likely to lift revenue per session, not the easiest tickets to ship
  • Senior operators monitored the work closely enough to keep momentum through implementation
  • Learnings fed back into media, creative, retention, and growth planning decisions

Why It Matters for Paid Media

A 10% increase in revenue per session is directly related to a 10% increase in revenue and a 10% improvement in every direct response metric that depends on revenue output. That is one of the few levers that can counter rising ad costs without asking the media team to find a new hack.

The takeaway: web merchandising and CRO should sit inside the growth system. When it is left to junior operators or buried behind product launches, brands miss one of the highest-leverage ways to make paid media scale faster and more profitably.

Where They Started

Total Revenue

Volatile

Up and down week to week — inconsistent YoY comps with no clear growth trajectory

New Customer Revenue

Under Pressure

New-customer acquisition under pressure with inconsistent year-over-year performance before the brand-campaign work

Contribution Margin %

~18%

A lot of wasted ad spend — heavy investment across Google brand keywords, CTV, podcast, and Reddit with diminishing returns

Decision Framework

Gut Feel

No contribution margin visibility, no incrementality measurement, budget decisions made on platform ROAS

“It’s not formulaic. It’s a gut decision.” — VP Marketing, December 2025

Same Budget. Better Allocation. Better Results.

Smarter Spend Allocation

Reallocated the least efficient dollars into higher-impact campaigns — no additional budget required. Same total spend, fundamentally different outcomes.

Creative That Builds the Brand

Creative that reinforces who the brand is — not generic direct response ads that could have come from any brand.

Measured by Business Results, Not Platform Metrics

Every campaign held accountable by contribution margin, brand searches, and new customer revenue — not in-platform ROAS.

Same budget, better allocation. The returns don’t stop when the ad does. They compound through brand searches and baseline revenue that no direct response campaign can build.

Contribution Dollars Up Sharply Year Over Year — No Trough

Contribution Dollars

≈ +50% YoY

Contribution dollars grew roughly 50% year over year after the least-efficient spend was reallocated into brand campaigns — no added budget.

Contribution Margin %

18% → mid-20s%

Contribution-margin rate improved year over year every month of the engagement — from roughly 18% the prior year into the mid-20s%, about a 29% year-over-year improvement in the strongest month.

Revenue & New Customers

Climbing

Total revenue and new-customer revenue grew year over year through the engagement — no short-term drop while margin improved.

DTC Revenue

Up YoY

DTC e-commerce revenue grew year over year through the engagement, giving the brand-campaign work room to compound beyond one-week paid-click performance.

Contribution $ vs Prior Year

Well Above

Weekly contribution dollars ran well above the prior year across the engagement — every month outpaced the prior year.

CM $ YoY Growth

Accelerating

Weekly contribution-dollar year-over-year growth strengthened through the period, accelerating month over month.

No blind trough. No observed revenue drop in this engagement. These results came from brand-building campaigns — not more direct response spend. Contribution dollars grew sharply year over year while revenue and new customers kept climbing. This is what actually happened.

Better-for-You Wellness CPG Brand · DTC + Retail

New-Customer Acquisition Turned the Corner

Social Following

341x Growth

From ~2 new followers/day in January to 683/day by March.

Daily Social Shares

+629%

22 shares/day → 161 shares/day in two months.

This is what an immediate inflection looks like: new-customer acquisition turned positive within weeks of the engagement — no trough, no waiting two quarters for brand to “kick in.” This is why Marathon Engine is built around senior operators, creative judgment, and measurement instead of a junior account team. DR spend buys a click that disappears tomorrow. Brand-building creates compounding demand that keeps lowering acquisition cost long after the campaign ends.

Current results from an engagement that started mid-January 2026 — not projections. Margin and revenue grew immediately, with no trough.

This engagement started in mid-January 2026 — less than two months ago. Contribution margin is up 37% YoY and weekly revenue is up 20%, climbing every week since we started. These are current results — not projections — with no trough on the way up. Unlike direct response, the demand brand-building creates persists and compounds long after the spend.

~$40M Multichannel Lifestyle Food & Beverage Brand · DTC + Major Retailer

1.93x Incremental ROAS — Proven by Six-Month Causal Holdout

Adjusted Incremental ROAS

1.93x

Every $1 of brand spend returned $1.97 in proven incremental revenue. 90% CI: 1.45x – 2.41x — entire range above breakeven.

vs. Direct Response

2.1x Higher

Brand incremental ROAS was 2.1x higher than the blended in-platform DR ROAS (0.91x) during the same period. Brand outperformed DR by every measure.

Retail vs. E-Commerce

2x Larger in Retail

Brand is profitable in e-commerce, but twice as profitable in building wholesale. Incremental retail lift was 2x larger than DTC — revenue you cannot reach with direct response ads.

This is a 6-month causal geo-holdout — the most rigorous test available. The platforms said 0.91x. The real return was 1.93x. And here’s what makes this fundamentally different from DR: while generating that 1.93x incremental return, these campaigns were also building brand searches, growing the audience, and lifting retail sales in channels with zero ad targeting. No direct response campaign does that. This is the proprietary brand-building playbook — and it outperformed everything on the DR side by every measure. But we have five more case studies showing the same thing.

The Results Replicate Across Categories and Channels

Both results below came from top-of-funnel brand-building campaigns only — no DR. Both outperformed direct response on the measured standards in these tests. Two more data points showing the pattern across categories. More case studies are being added continuously.

Global Outdoor Gear Brand · Wholesale + DTC

Causal Revenue Lift at Major Retailer

  • Creative iteration with true diversity — more shots on goal, not just DR variations
  • Larger funnel ready to capture demand — more people who already know and trust the brand

By day 60, you’re less dependent on the auction — because you’ve built a fundamentally larger body of people who proactively seek you out before they ever see a direct response ad. And the data is clear: this should not be a blind sacrifice. We look for contribution-margin proof in weeks, not months, and measure whether the full funnel is outperforming bottom-funnel spend alone.

The Information Is Public. The Execution Isn’t.

The Research

The Data Has Been Clear for Years

Binet & Field, Les Binet, James Hankins — decades of rigorous research showing brand investment drives long-term growth. The data is public. The findings are not controversial. Any agency can read the same papers.

The Gap

Most Agencies Won’t Do It

DR is easy to measure and easy to attribute. Brand is harder. Most agencies are structured, incentivized, and staffed to optimize for the metric that’s easiest to show in a dashboard — not the one that actually drives the business.

The Difference

We Built the System to Execute It

Measurement infrastructure that captures brand impact daily — not quarterly. Causal methodology that separates signal from noise. The operational capacity to run brand campaigns the same way most agencies run DR: rigorously, continuously, and accountable to real business outcomes.

This is better performance — not a tradeoff. The measured incrementality on brand campaigns consistently exceeds DR in every account we manage. The difference isn’t the insight — the research is public. The difference is the proprietary playbook and measurement system we’ve built to execute on it, measure it in real time, and prove it works.

What This Builds

What We Measure

Business outcomes, not platform metrics.

  • Incrementality — causal measurement of what’s actually driving growth
  • Brand Health — branded search volume as the leading indicator of compounding demand
  • Contribution Margin — the metric that actually matters for a sustainable business
  • Audience Growth — new people who know the brand, expanding the future addressable market

Creative That Compounds

Every piece of creative is measured against business outcomes. What works gets scaled. What doesn’t gets replaced. The learnings compound over time — building a creative system that gets stronger with every campaign.

The Compounding Effect

Every dollar of brand investment creates people who come to you without ever seeing or clicking a direct response ad. They search the brand. They memorize the URL. They come directly.

This stream of revenue grows and compounds over time — reducing dependence on the auction, increasing optionality, and growing owned audiences.

One client saw contribution dollars up 60% in 80 days. Another hit seven consecutive weeks of CM$ growth with no decline. This isn’t a long-term bet — it pays out in weeks.

What Success Looks Like

A fundamentally larger funnel of people who already know and trust your brand — less dependence on the auction, more control over your own growth.

That means: More demand to capture, less cost to capture it, higher margins, and a growth engine that keeps compounding after the holiday.

The Playbook Works. The Proof Is in the Data.

Across Marathon Engine customers — denim, wellness, footwear, food & beverage, outdoor gear, beauty, and web merchandising engagements — the pattern is consistent. The highest-leverage growth work improves business economics, not just channel dashboards. Brand campaigns have driven stronger incremental ROAS than saturated DR in these tests. CRO and merchandising lift revenue per session, making every media dollar more effective. These results come from a proprietary operating playbook and measurement infrastructure built around contribution dollars, not platform screenshots.

Early Improvement

These brands saw contribution margin, revenue, and new customer acquisition improve from the first weeks — driven by top-of-funnel brand campaigns, not more DR spend

Protected Near-Term Health

In these examples, we did not observe a revenue drop or contribution-margin decline while the media mix shifted. That is the point to prove before brand investment gets scaled.

Brand Outperforms DR — Every Time

1.93x–2.39x incremental return on brand campaigns alone — higher than every DR tactic tested in the same accounts, proven by independent causal geo-holdout tests with statistically significant positive lift (90% CI lower bound above 1.0x on one; 97% probability of positive return on the other)
