Our point of view

We don't pretend Meta's number is real.

Every ad platform reports inflated, self-serving numbers. Chase them and you scale spend that isn't making money. We optimise against one honest metric instead: blended marketing efficiency - true revenue (or pipeline) divided by total spend, across every channel.

Whether you sell DTC products or B2B contracts, the discipline is the same: diagnose, produce, measure - judged on outcomes, not the platform's fairy tales.

Meta says 8.2x ROASYour bank says 3.1x

Platforms claim credit for sales they didn’t cause. We measure blended efficiency across every channel - not each platform marking its own homework.

Last-click attributionTotal spend ÷ true revenue

One honest number you can run the business on: MER for ecom, true cost per qualified lead and pipeline for B2B.

Pretty in-platform dashboardsOne view, reconciled to outcomes

Meta + Google for ecom revenue; LinkedIn + Google for B2B pipeline. Each channel reconciled to real outcomes - never blended into a number that doesn’t make sense.

How it works

The whole loop, in one place.

Whether you sell DTC products or B2B contracts, the engine works the same way.

01

Diagnose

We run your account and competitors through the engine - honest MER, attribution gaps, and the proven creative angles you’re not running yet.

02

Produce

Tusk Design turns those gaps into fresh ad concepts every week, grounded in the Creative Vault of proven, long-running winners.

03

Measure

Everything is judged on blended efficiency - real revenue or pipeline ÷ total spend. Budget follows what actually works.

The agency

Solo-but-superpowered. Boutique team, platform leverage.

Most agencies sell you hours and hope. We sell you an engine. Because we build our own tooling, a lean senior team runs accounts with intelligence and creative output bigger shops can't match - and we're honest about what's actually working.

  • Senior, ex-Ogilvy strategists - no junior account handlers learning on your spend.
  • We built our own intelligence and creative-production platform - so a small team operates at the scale of a much bigger one.
  • One team owns diagnosis, creative, and measurement end to end.
