The operating system behind profitable growth.
Marathon Engine combines fractional CMO judgment, Marathon Data measurement, and the operators who know how to turn the numbers into decisions. We plug into your team and agencies, then guide what to fund, stop, test, fix, and explain.
Seven components. One weekly decision system.
Most media partners optimize for their slice. We're built around a different question: where does the next dollar produce the most incremental contribution?
That takes more than a media buyer. It takes a measurement foundation that can quantify brand spend, a creative engine that feeds signal back into strategy, a retention lens that weights LTV against acquisition cost, and a founder-led operating cadence so the business keeps making disciplined decisions. Every component below is connected — the measurement tells us what's working, and the weekly rhythm turns it into budget, channel, resource, demand-planning, and finance decisions.
Seven components, one measurement core, one senior decision cadence. Every dollar's return is read by Marathon Data — so the system optimizes for incremental contribution, not seven separate dashboards.
What we actually do.
Each component is active from day one. None of them are bolt-ons.
Brand media management
Plan, buy, and optimize brand campaigns as part of one integrated media mix — not a separate "awareness budget" handed to a different team. Briefing, channel selection, frequency, and audience sequencing run in the same rhythm as performance.
Customers acquired with brand exposure convert better, churn less, and carry higher LTV — none of which shows up in last-click. We built the measurement to prove it, so the investment decision stops being an argument.
Direct-response paid media
Full management of performance media — Meta, Google, and beyond — with a contribution-dollar lens. We set the guardrails: the defensible MER floor for your margin and LTV, where incremental spend hits diminishing returns, and how to allocate on real incrementality, not platform ROAS.
Performance media generates revenue at any spend level. The question is whether it generates profit. We manage to contribution dollars and payback — and our pay isn't tied to how much we spend.
CRO · web merch · landing pages
Audit and prioritize conversion lift, build purpose-built landing pages for paid campaigns, run structured A/B tests, and advise on merchandising — what gets featured, how products are sequenced, how the site treats cold vs. warm traffic.
Revenue per visitor captures both conversion and order value, so a lift makes every future session more valuable. For one subscription CPG brand, our homepage hero A/B test increased revenue per visitor by 27.5% at 97% confidence; the winner is now live to all traffic.
Creative strategy & analytics
Run creative as a production process, not brainstorms: a defined testing framework, briefs grounded in performance data, structured analysis of what's driving incrementally better results, and a clear loop from analytics back into the next brief.
Creative is the highest-variance input in paid media — most brands are running on fatigue without knowing it. A disciplined analytics layer turns that variance into edge: the brand that learns faster wins the auction.
Retention & LTV (profit) strategy
Strategy and analytics for email, SMS, subscription mechanics, and post-purchase — built to grow contribution dollars per customer. We analyze cohort LTV, find where repurchase drops off, sequence retention to extend payback, and connect LTV assumptions to your acquisition ceiling.
Your acquisition economics are a function of LTV. Knowing what a customer is truly worth lets you spend to acquire at a fundamentally different cost than a brand guessing — retention doesn't just lift margin, it unlocks a higher ceiling for profitable acquisition.
Forecasting & demand-planning
Build and maintain the bridge between media forecasts and business-wide planning: scenario modeling for spend changes, guidance on framing projections for your CFO and board, and a disciplined process for updating forecasts as real data lands.
The brands that scale fastest are the ones where marketing and finance trust each other's numbers. Disconnected forecasts create stockouts, cash crunches, and reactive spend. A shared model prevents all three.
Founder-led CMO operating system
We sit in the weekly operating rhythm with your team and agencies: reviewing Marathon Data, deciding what to fund, stop, test, fix, and explain, and translating the plan into CFO, board, channel, resource, and demand-planning decisions.
The biggest risk in a brand + performance build isn't one tactic — it's bad decisions across silos. We built Marathon Data and the operating cadence because, as brand founders, we needed a way to keep capital allocation, customer quality, creative, site, retention, and finance aligned.
From day one to compounding growth.
The engagement can include execution, but the core product is the senior operating system: measurement, judgment, weekly decisions, and a practical plan your team can act on.
Measurement foundation
Before we spend a dollar, we know what we're measuring and why. We audit your attribution, establish incrementality baselines, and build the framework that tells us whether the build is working — in terms finance can trust, not platform metrics.
Engine architecture
We design the media mix, channel strategy, creative framework, and decision rules for your specific economics — margin profile, LTV curve, inventory reality, current efficiency, and channel mix. Not a generic plan; built from your numbers.
Weekly operating cadence
Every week, the system turns data into action: where to push, pull back, reallocate, brief new creative, sequence site tests, pressure-test demand planning, and explain the move to finance.
Execution compounds
Some brands have us execute the whole stack; others keep their team and agencies in place while we guide the system. Either way, learnings feed the next decision, and the operating cadence gets sharper as the data accumulates.
"Fast results, deep partnership. We stay in the room for the strategic and emotional parts of the transition — not just the workstream updates."
Built different. Compensated different.
We spent 15 years making these calls with our own company's money. That changes what we pay attention to.
