Expands to New San Francisco Headquarters to Support Increasing Demand for Health Care Transparency Solutions

SAN FRANCISCO – January 7, 2013 – Driven by strong demand for Health Care Transparency, Castlight Health signed a record number of new employers and payers as customers in 2012. To support its rapid growth and expanding headcount, which grew by more than 60 percent over the past year, Castlight has moved to a new, larger headquarters in downtown San Francisco.

During the past several months, Castlight added dozens of new customers, including ConAgra Foods, Indiana University, Butler University, Carlson, Celadon Trucking, Ivy Tech Community College, Phillip Services Corp., and Whitcraft Group. Through their employers and health plans, millions of people now have access to Castlight’s health care management suite, which provides access to the critical health care quality and pricing information they need to lower costs and improve outcomes.

The new headquarters, located at Two Rincon Center, will allow Castlight to accommodate its rapidly growing team, including planned new hires across engineering, sales, marketing and account management.

“2012 proved to be the most successful and exciting year in our company history,” said Dr. Giovanni Colella, CEO and co-founder, Castlight Health. “Our growing customer portfolio demonstrates the market desire for Health Care Transparency, as employers recognize the power of helping employees make more informed decisions about their care. The health care transparency groundswell is transforming health care, and Castlight is well positioned to be the leading force and innovator in the market in 2013.”

In addition to record customer acquisition, Castlight achieved a number of company milestones and added significant new enhancements to its leading health care management suite in 2012. This included securing $100 million in Series D funding to capitalize on the growing demand for Health Care Transparency solutions, and introducing Castlight Mobile, which enables users to access Castlight’s health care management suite on their preferred mobile devices. The company also strengthened its management and advisory teams with the addition of industry leaders and veterans.
