How a 1M-user AI tool doubled qualified signups without raising CAC

They were scaling spend but not paying users. We rebuilt tracking, cut the waste, and pointed the budget at people who actually convert.

The challenge

Busy account, flat revenue

The tool had scale, over a million users and a healthy ad budget, but the paid account was optimising toward free signups. Volume looked great on the dashboard while paying conversions stayed flat.

Spend was climbing and nobody could say which clicks were actually turning into revenue. The brief was simple: stop paying for signups that never convert.

What we did

Three moves, in order

1

Rebuilt conversion tracking

We reconciled the account against the CRM, killed the soft conversions, and set it to fire on a real paying event with values attached, so bidding finally had a true signal.

2

Plugged the spend leaks

Brand searches were split out, a living negative-keyword list went in, and Performance Max got real guardrails so it stopped harvesting traffic they already owned.

3

Rebuilt the signup path

Message-matched landing pages and a lower-friction trial turned the same expensive clicks into far more qualified signups.

The Heureux approach

Once the bidding chased revenue instead of raw signups, the same budget started finding paying users, not tyre-kickers.

The result

More paying users, same budget

Within a quarter, qualified signups more than doubled while cost per signup fell by over a third. Because bidding was finally pointed at revenue, the trial-to-paid rate climbed too, so the growth was in paying users, not vanity numbers.
