The business

A Series-A SaaS company, under real pressure to demonstrate pipeline to its board, had poured paid budget into brand-term search and retargeting. Both lines reported strong conversion rates and were treated internally as the safe, efficient core of the media spend — the campaigns you never cut because the dashboard always showed them working hard for the money.

What triggered the audit

Fresh board scrutiny on burn rate prompted a hard question about whether paid marketing was genuinely creating demand or merely taking credit for it. Brand-term search and retargeting are precisely where that distinction tends to blur, so the audit focused on separating incremental, paid-created demand from demand the company already owned.

What the audit found

The two "safe" lines turned out to be largely buying customers the company had already earned. The brand-term and retargeting conversions were overwhelmingly people who already knew the product — inbound demand generated by sales conversations, word of mouth and organic discovery — and who would have converted through those owned channels anyway. Paid simply intercepted them at the last click and invoiced for the result. Because the reported conversion rates were high, the spend looked like the most efficient in the account, when in reality it was the least incremental. The company was paying roughly $41k a year to re-buy demand it already had, while genuine top-of-funnel growth went comparatively underfunded.

How we produced this finding

MarginFix arrived at the brand/paid overlap finding by refusing to take attribution at face value — the SaaS spend was run through the agentic AI audit framework and tested for real, incremental impact, then checked and signed off by a named senior auditor before anything was reported.

Data sources: Spend by channel, campaign, creative and audience, joined to conversion and revenue data — plus a geo-holdout test built to isolate what brand/paid overlap genuinely caused rather than what it merely claimed.

Key frameworks: Geo-holdout incrementality testing, Marketing Mix Modeling (MMM) and attribution-correction and inflation-factor analysis, cross-checked against Analytic Partners ROI Genome, Google Meridian and Meta Robyn.

Human validation gate: Every incrementality read is re-run against your own data and signed off by a named senior auditor before it ships — no automated output ever leaves the building unreviewed.

What we changed

Cut brand-term defense spend to the minimum genuinely needed to hold position against real competitor bids on the company’s own name.

Paused the redundant retargeting that was intercepting already-committed buyers, and redirected that budget into genuine net-new demand generation.

Applied incrementality tracking to the remaining paid spend, so efficiency is measured against demand actually created rather than clicks conveniently harvested.

Reframed the marketing narrative for the board around incremental pipeline, giving a cleaner, more defensible efficiency story ahead of the next raise.

The result

$41k a year freed from spend buying demand the company already owned, redeployed into real growth — a 7× return on the $5,950 Audit + Sprint fee. For any founder defending burn to a board, the sting is that brand-term and retargeting were the “safe” lines nobody questioned. If your most efficient-looking campaigns simply intercept demand you’d win anyway, you are paying to re-buy your own customers — and that spend looks great right up until you test it. A fixed-fee audit gives you a defensible, incrementality-based story in days, ahead of your next raise.

From kickoff to signed-off findings: 5 days — inside our fixed 5–7 day window.
