Case Study: Fortune 500 Fast Casual Dining Brand achieves 144% increase in marketable audience and optimized paid media attribution with Amperity

Fortune 500 brand uncovers unknown audiences, significantly increases reach, and optimizes paid media

Fortune 500 Fast Casual Dining Branding Company turned to Amperity to solve a major data blind spot: roughly 100 million in-store customers were non‑loyalty, PII‑sparse credit‑card transactions, preventing personalization, customer activation, and paid‑media attribution across the brand.

Amperity deployed its Customer Data Platform—using patented identity resolution and proprietary audience expansion—to build an always‑on Customer 360 that probabilistically stitched fragmented records and created marketable audiences from sparse transactions. The solution delivered measurable impact: 8% deduplication in the loyalty database, a 144% increase in marketable audience, the ability to reveal 30–50% of previously unknown in‑store purchasers, and a unified Customer 360 ingesting billions of historical records plus 30M+ new records daily, enabling improved targeting, attribution, and optimization of paid media.
