Case studies

Verified results, not promises

Eight engagements, written up honestly: what the situation was, what we changed, and what it produced. Where a number is a platform-reported metric we say so; where it is contribution margin, that is what it says.

Alder & Oat

Supplements
Situation

Spend was growing 20% month on month while contribution margin went backwards.

What we changed

Rebuilt attribution in Triple Whale and found 31% of spend was acquiring customers who returned on first order.

Outcome

3.4× contribution return in 90 days

The collaboration felt clear, structured, and refreshingly straightforward from the very beginning. Our ideas were not only understood but translated into a design that genuinely reflects who we are.

Casa Verde

Home & Garden
Situation

One winning video from eighteen months earlier was carrying the whole account.

What we changed

Moved to 48-hour production cycles and tested 40 angles in six weeks, with hooks varied independently of body.

Outcome

Creative refresh cycle cut from six weeks to 48 hours

Six weeks of production turned into forty-eight hours. We now test more angles in a single week than we used to ship in a quarter.
Sofia MarchettiCo-founder, Casa Verde

Northline

Beauty
Situation

Creator costs of $300 per video capped testing at four assets a month.

What we changed

Replaced the creator pipeline with custom AI avatars and put the saved budget into media.

Outcome

10× more creative angles tested per month

We were paying three hundred dollars a video and waiting on creators. Now we produce unlimited variants and the only bottleneck is how fast we can test.

Trail & Peak

Outdoor
Situation

Platform-reported ROAS was healthy but the brand was not profitable at scale.

What we changed

Restructured campaigns around profit contribution, killed the prospecting campaigns that never paid back, and rebuilt retargeting around margin.

Outcome

−31% CAC, held through two seasonal spikes

They rebuilt our account structure from the ground up. CAC dropped inside the first month and it has held through two seasonal spikes.
Jonas WeberEcommerce Director, Trail & Peak

Sable Studio

Jewellery
Situation

High ROAS masked cash burn from returns and discount dependency.

What we changed

Switched optimisation target from ROAS to contribution, removed two permanent discount codes and re-cut the creative to sell on product rather than price.

Outcome

2.8× average order value on retained creative

Every recommendation came with the numbers behind it. Nothing was guesswork, and the conversion lifts compounded faster than we projected.
Priya RamanCMO, Lumen Skincare

Northbeam Health

Health
Situation

Feedback loops were too slow to find winning creative before budgets exhausted.

What we changed

Installed a 48-hour testing engine with a fixed decision rule: scale at threshold, kill below it, no debates.

Outcome

34% average ROAS lift across nine brands

The speed of iteration is the part that surprised us most. Feedback on Monday was live by Wednesday, every week, without a single dropped deadline.
Charlie NguyenFounder, Halo Coffee

Porter & Lane

Furniture
Situation

Founders were making tactical media decisions between other work.

What we changed

Embedded a strategist in Slack with weekly optimisation calls and a written weekly read of the numbers.

Outcome

24/7 strategic access, zero order-taker meetings

They untangled a reporting mess four agencies had left behind. For the first time we can see exactly which channel pays for itself.
Sarah WhitfieldMarketing Director, Fieldwright

Multi-brand portfolio

Ecommerce
Situation

Nine brands managed with inconsistent process and no shared learning.

What we changed

Standardised creative testing, attribution and reporting across the portfolio so a winning angle in one brand was tested in the rest.

Outcome

$500K+ monthly spend managed at 3.1× average multiple

We doubled spend and kept efficiency. That is the whole game, and they made it look routine.
