Calista Technologies

Calista Technologies was a desktop and GPU virtualization startup founded in 2006 in San Jose, California by Neal Margulis, backed by Lightspeed Venture Partners, Greylock, and Western Technology Investment. Its software improved the user experience of 3-D and multimedia delivery for virtualized desktop deployments and server-hosted applications running on Windows Server Terminal Services (Remote Desktop). Microsoft acquired the company in 2008 and folded its GPU-virtualization technology into RemoteFX. The company is defunct and publishes no live developer, documentation, or API surface; its former domain (calistatechnologies.com) is now a parked domain listed for sale.
