Citrix Systems, Inc. is an American company that develops software solutions in networking, application and desktop virtualization, server technology, cloud-based computing, and offers software as a service (SaaS). Citrix was established in 1989, originally as Citrus, by Ed Iacobucci, a former IBM developer. The company soon developed Citrix Multiuser, a port for OS/2, which used Independent Computing Architecture (ICA) that allowed multiple simultaneous users to access server applications, even from computers not built to run OS/2. Citrix currently employs 9,000 people and is headquartered in Santa Clara, California, USA.
