Nu Mexico improved paid
performance and achieved
8x ROI with CHEQ
The challenge
- As a division of NuBank, Nu Mexico is laser-focused on maintaining its edge in a hypercompetitive space.
- Nu Mexico spends significantly across paid media channels including Google, Meta, and TikTok.
- Concerns grew around a lack of visibility into targeted audiences and potentially wasted ad spend.
The solution
CHEQ protects Nu Mexico’s paid marketing channels from invalid traffic, including malicious bots and fake users.
During an initial 30-day trial period, CHEQ’s security platform revealed that up to 10% of traffic driven through paid channels was invalid, with malicious bots and automation tools depleting digital marketing budgets. With this vital information, the Nu Mexico team quickly implemented significant and impactful performance improvements by reallocating wasted ad spend.
“CHEQ has been an amazing partner every step of the way. They’ve helped us improve the efficiency of our ad spend and we’re seeing 8X ROI from the investment.”
