Profitable growth, proven — not promised.
Across the portfolio, Marathon grows the business on the metrics that matter: contribution dollars, incrementality, and conversion-rate gains that compound across the P&L.
More profit in the long term — and the short term.
In every account we've taken over, we've seen immediate improvement — not the "trough of despair." We've made the expensive mistakes already, on our own money.
The scoreboard is revenue, contribution dollars, new customers, and MER — not platform-reported ROAS or last-click credit.
Geo-holdouts isolate brand-media lift, while CRO winners only ship when the test earns its way to 100% of traffic.
Proven incremental return on brand media.
Each result below is a controlled geo-holdout incrementality test isolating brand campaigns — every dollar of return is incremental, with the confidence range shown.
Real business impact — fast.
Recent examples across consumer brands where growth and profitability moved together, including several early-window wins from the first ~90 days with Marathon.
Most brands buy growth by giving up efficiency. This was the opposite: the business got bigger and more profitable at the same time.
Revenue, profit, efficiency, and new-customer growth all hit highs in the same window — broad-based real impact, not a cherry-pick.
New customer CAC has come down 30%.
After 2 months measuring with Marathon
Profit is up 4x. We just had our best day ever outside of BFCM.
After 6 weeks of brand-optimized spend
This ad has the lowest CAC of any ad I’ve run in 4 months—and it’s on my most expensive product.
An organic post they never would have used as an ad without Marathon
We do CRO, too — and it compounds into the P&L.
Beyond media, Marathon runs a continuous, structured on-site testing program. Only validated winners ship to 100% of traffic, so the upside keeps paying across paid and organic sessions while failed tests cost nothing but a sharper read on what works.
Conservative annualization from each winner's own page or segment GA revenue.
Two engagements, start to finish.
What the starting state looked like, what we changed, and the result.
From "gut-feel" allocation to measured contribution growth.
Thin, volatile contribution margin, and a decision framework the VP of Marketing described as "not formulaic — a gut decision."
Ran brand + performance as one system on Marathon Data; reallocated the least-efficient spend; defended brand investment with measured incremental return.
Contribution dollars +32%, revenue +39%, and new-customer revenue +37% — Mar–May 2026 monthly average vs the Jan–Feb pre-engagement baseline — with discount rate down 3.1pp. No trough.
Proving brand pays — 1.97x incremental, validated by a controlled holdout.
Performance-saturated, with brand spend that was unmeasured — and therefore impossible to defend or fund.
Ran a six-month geo-holdout isolating brand campaigns on Marathon Data, measuring incremental revenue against a matched control.
1.97x validated incremental brand ROAS; 2x larger lift in retail than ecom; more than 2x the return of saturated direct response; total-business revenue +28.7% YoY in January. No trough.
Why these numbers hold up.
Causal, not correlational. Incremental ROAS comes from geo-holdout tests — comparing matched markets with and without brand spend — not last-click or platform-reported attribution.
Contribution dollars, not vanity. Results are measured in profit (revenue minus variable costs), new-customer revenue, and LTV-weighted payback — the numbers a CFO can defend.
Confidence ranges shown. Every incrementality result carries its confidence interval. When the whole range sits above breakeven, the call is clear.
Traceable to the system of record. Every figure ties back to the brand's own data in Cube, Shopify, Amazon, and the platform ledger — not a slide we made up.

Brands anonymized to category to protect our customers. Contribution figures combine actual revenue with each brand's standard variable-cost assumptions. Pre/post YoY framing isolates Marathon's engagement period from the same months a year prior. CRO revenue is conservatively annualized from each winner's own page or segment GA revenue. Incremental ROAS figures are from controlled geo-holdout measurement; all figures trace to the brand's system of record.
