Case Study: Markerstudy achieves 120% policy growth and £5M in claims savings with Cloudera Enterprise

Achieved 120% increase in policy count in 18 months

Markerstudy Group is a fast-growing UK insurer serving over 1.75 million customers and generating more than £1.4 billion in revenue. Facing explosive data growth from its Insurer-Hosted-Rating (IHR) hub—about 25 million quotes per day—the company struggled with costly storage, capacity limits, deleted older records, and siloed analytics that left actuaries and underwriters with only 5% of quote data for analysis.

Markerstudy implemented Cloudera Enterprise with SAS, using a Hadoop cluster with Spark and Impala to ingest 20,000+ messages per second and make 100% of quote data available within seconds. The platform delivered rapid ROI: a 120% increase in policies (500k to 1.1M) in 18 months, approximately £5 million saved through improved fraud detection, 20% annual savings on rate updates, a 60% reduction in fraudulent applications, and a 50% drop in customer cancellations.
