Case Study: Nu Mexico achieves 8X ROI and improved paid-media performance with CHEQ

How Nu Mexico Improved Paid Performance & Achieved 8X ROI with CHEQ

Nu Mexico, a division of the largest digital banking platform, faced growing concerns about wasted ad spend across high-investment paid channels like Google, Meta, and TikTok and partnered with CHEQ to gain visibility and protection against invalid traffic. CHEQ’s solution — protecting Nu Mexico’s paid marketing channels from bots and fake users — was deployed to diagnose and stop fraudulent activity affecting performance.

During a 30‑day trial and subsequent engagement, CHEQ detected up to 10% invalid traffic, blocked roughly 8 million bad actors across paid campaigns, and enabled reallocation of wasted spend to real customers. As a result of CHEQ’s protection, Nu Mexico achieved an 8X return on investment in the first year and a 60% improvement in invalid click rate, substantially improving paid performance.
