AI-Powered Performance Marketing

We turn paid on last, after discovery and data are fixed, because automation amplifies whatever shape your account is already in.

The problem

Optimising to revenue teaches the model to sell your worst products

Most accounts feed platforms revenue and get exactly what they asked for: volume on thin-margin lines. Feeding contribution margin instead changes the answer within a fortnight.

The second constraint is structure. On one account we consolidated 41 campaigns into 9 intent-shaped groups and the learning phase got 2.4 times faster, which did more work than the bidding model did.

What you actually get

Every engagement ships these. No line items you cannot point at.

Margin-fed bidding

Real cost of goods in the conversion signal, so the model optimises the number your finance team recognises.

Account restructure

Campaigns consolidated into intent-shaped groups with enough signal per group to learn in a week.

Guardrails and rollback

Frozen exclusions, a margin floor and a written rollback rule agreed before the model gets authority.

Incrementality testing

Geo and holdout tests on brand and retargeting, so you stop paying for conversions you already had.

How we run it, week by week

Weeks 1 to 2

Structure and signal

Account consolidation, conversion signal rebuilt on margin, guardrails written down.

Weeks 3 to 5

Exploration

The model widens deliberately. CAC can rise here, and the exploration budget is agreed in advance.

Weeks 6 to 8

Consolidation

Winners scaled, losers cut, creative testing framed on one axis per batch.

Ongoing

Monthly incrementality

A live holdout somewhere in the account at all times, so the reported number stays honest.

Stack we work in

Platform-agnostic. We work in whatever you already own and tell you honestly when it is the constraint.

Questions buyers ask us

Because paid traffic landing on a broken search box or a thin product page is the most expensive way to discover those problems. Fixing the surface first changes the economics of every click afterwards.
