Show HN: We paused our best-performing ad

1 points by bmahir 12 hours ago

We paused a Google Ads campaign because the CAC looked too high. $140 per signup, while the others were under $100.

Seemed like a no-brainer. Cut the expensive one.

Six weeks later, we realized we’d made a mistake. Those “expensive” users actually stuck around, churned less, and upgraded more. Their LTV was double the others.

Turns out, we’d shut off our best-performing channel, because our data was scattered. Ad spend in one place. Revenue in another. No way to see the full picture.

We spent months optimizing for the cheapest CAC… not the most profitable growth.

That’s why we built Kruxel — a decision engine that helps you answer questions like:

Which channels actually pay back fastest?

Which campaigns bring in high-churn users?

Where should you put your next $10k in ad spend?

No dashboards. No guessing. Just clear answers.
