Castlight Health

What Castlight Health does

Castlight Health operates a healthcare navigation platform that serves as a digital front door to employer benefits ecosystems, combining a personalized member app with live Care Guides (including RN-led clinical advocacy) and an ecosystem of 30+ integrated digital health partners via 250+ pre-built, two-way data integrations. The platform's core technology is a predictive personalization engine, developed over nearly two decades on billions of aggregated health data points, which identifies member needs and surfaces tailored care, benefits, and program recommendations. Beyond navigation, Castlight has expanded into clinical services including Virtual Urgent Care, Behavioral Health, Health Coaching, a GLP-1 and Weight Management Program, Diabetes Education, Nutrition Education, and Advanced Primary Care (via the 2022 merger with Vera Whole Health into apree health), and in April 2026 introduced Prism, a generative AI conversational guide for benefits navigation.

The company sells primarily to large self-insured employers (Fortune 500 across 30 industries), health plans (often as a white-labeled front door), and benefit consultants, using a B2B enterprise sales motion with annual subscription contracts structured on a per-member-per-month basis. It claims 6M+ members served, customer NPS of 67, and Care Guide NPS of 86. Castlight was founded in 2008, went public on NYSE under CSLT, was taken private via its 2022 merger with Vera Whole Health to form apree health, and is led by CEO Jonathan Porter (appointed April 2025). It is headquartered in San Francisco with an R&D presence in India, and holds NCQA certification for its health assessments.
