Case Study: Drawbridge achieves 97.3% cross‑device identity precision and 200% marketing uplift with Cloudera Enterprise

Drawbridge Uniting the User Experience Across Three Billion Digital Devices with 97.3 Percent Precision

Drawbridge is an anonymized cross-device identity company that maps one billion consumers across more than three billion devices. Its challenge was to unite user experiences across PCs, smartphones, tablets and connected TVs by ingesting and processing trillions of observations and billions of daily requests to create accurate single digital identities at massive scale.

Using Cloudera Enterprise (with Spark, Hive, Kafka, Giraph) and probabilistic graph and machine-learning models, Drawbridge links devices into single user profiles and cut time-to-actionable insights from one hour to ten minutes. The solution achieved 97.3% precision (Nielsen), delivered more than a 200% uplift in advertising performance, produced a telecom campaign with 2.5x mobile and 3x in‑store efficiency, and helped the company double revenue each year for three years.
