Cost per new customer cut by a third
Kubera Health. How a creative testing habit brought profitable spend back.
Why it mattersMost brands lower CAC by spending less. Cutting it a third while spend went up means the creative finally did the work.
Where they started.
Kubera Health had scaled paid spend fast and watched the cost per customer climb with it. Creative was stale (the same three ads had run for months), the landing pages hadn't changed since launch, and the Meta account structure fought itself every time the budget moved. The goal wasn't to spend less; it was to make growth profitable again so spend could keep climbing.
“We doubled the spend and the cost per customer still fell. I didn't believe creative testing would be the thing, but it was.”
Every engagement is different; results shown are not a guarantee. How we present results
What we did about it.
The 30-Day Plug-In audit pointed at creative, not targeting: the account had burned through its audiences with the same three messages. The plan put creative on a real testing cadence (new angles every week, judged on cost per new customer, not clicks) and rebuilt the landing pages and account structure so winners could scale without breaking. It is the kind of work we run for founder-led startups.
Cost per new customer came down by a third while profitable spend roughly doubled. The testing cadence surfaced a winner about one ad in six, average order value rose 14%, and the rebuilt account structure let the winners scale without falling apart. By the first 90-Day Rebuild, the question had flipped from "why is CAC climbing?" to "how fast can we feed this?"
