About Castlight Health, INC.

Castlight Health, Inc. is a U.S. healthcare technology company focused on healthcare navigation and employer health-benefits optimization. Its core customer base has historically consisted of large employers and health plans that want to steer members toward appropriate care, improve engagement with benefits, and help manage healthcare spend. Founded in 2008, Castlight initially became known for healthcare price-transparency tools and later expanded into a broader digital navigation platform supported by clinical and member-support services.

As a result, CSLT should be viewed today as a legacy public-company ticker rather than an actively traded listed equity, even though the business and brand remain in use within a larger healthcare group structure. The company has been associated with San Francisco historically, while more recent public references also point to Sandy, Utah as an operating location; SEC filings have likewise referenced a San Francisco business address.

The company combines technology with clinical and benefits expertise, positioning itself as a navigation layer between employers, health plans, and employees. This places Castlight in a competitive segment that overlaps with healthcare benefits platforms, care-navigation vendors, and digital health ecosystems serving self-insured employers.

In April 2025, Castlight launched a virtual urgent care solution integrated into its healthcare navigation app, reinforcing its move toward more seamless digital access to care. In February 2025, the company was also named as one of the participants in an alliance supporting rural healthcare transformation efforts in the United States, highlighting its relevance in broader care-access and system-modernization initiatives. In April 2026, Castlight published new survey findings on employer health-benefits usage, underscoring that its go-to-market messaging continues to emphasize the gap between benefits design and real employee behavior.
