WTW Partners with Klarity to Integrate Wearable Data in Life Insurance Underwriting
WTW has formed a strategic partnership with health data analytics provider Klarity to integrate wearable technology data into life insurance underwriting processes. Klarity has developed a sophisticated risk scoring tool that produces individual mortality scores by leveraging over six million life years of data gathered over 12 years, complemented by external health data such as metrics from smartwatches and other wearable devices. This innovative approach addresses the shortcomings of traditional underwriting models, which often miss critical health indicators, by incorporating AI-driven insights and diverse health and behavioral data, including activity levels, heart rate, and sleep patterns.
WTW has independently validated Klarity's mortality scoring model using the National Health and Nutrition Examination Survey (NHANES) data, confirming its capability to offer granular assessments of individual mortality risks. The enhanced risk stratification enabled by this model supports more accurate insurance pricing and could potentially transform underwriting accuracy in North America. Key executives from both organizations emphasize that this model not only improves the precision of mortality predictions but also enhances customer engagement and loyalty through personalized pricing strategies.
The adoption of predictive analytics that utilize wearable data marks a significant evolution in life insurance underwriting, promising more tailored pricing and improved risk assessment. This approach not only refines mortality prediction but also opens opportunities for improving the overall customer experience and engagement within the insurance sector. The collaboration reflects broader industry trends toward the integration of advanced data analytics and AI to drive more dynamic and responsive underwriting processes.
WTW, which recently reported a notable 134% year-over-year increase in net income for Q2 2025, is advancing its consulting and technology capabilities through partnerships like this. The initiative aligns with the growing emphasis on leveraging real-time health data to enhance business intelligence, compliance, and risk management within the life insurance industry. This collaboration underscores the insurance sector’s ongoing shift towards AI-driven, data-rich underwriting solutions that aim to balance risk accuracy with customer-centric offerings.
