Gio co-founded Castlight in 2008, along with Todd Park who’s since found different employment! Castlight changed its name several times, and was very secretive about exactly what it was up to. However, if you raise $80m in venture funds eventually someone will figure it out, and Castlight’s cover was blown in the NY Times in August. You’ll see that they have great ambitions to change the shopping experience of American health care consumers and are already working with Safeway. If you go far enough back Gio is a psychiatrist trained in Milan, but he’s best known pre-Castlight for founding RelayHealth and eventually selling it to McKesson. As for Castlight itself? You’ll have to wait until Launch! for that demo.
