Castlight Health is a San Francisco based healthcare information company. The company was founded in 2008 and offers enterprise healthcare technology allowing employees to compare healthcare providers across a variety of metrics to optimize pricing and quality. The Castlight platform is licensed through a business-to-business-based subscription model.

In 2012 the company secured $100 million in investment funds. In 2014 the company had its initial public offering, valued at $2 billion, which attracted criticism for being part of a potential economic bubble.
