Citrix Systems, Inc. is an American multinational software company that provides server, application and desktop virtualization, networking, software as a service (SaaS), and cloud computing technologies. It was founded in Richardson, Texas in 1989 by Ed Iacobucci, who served as chairman until his departure in 2000.
The company began by developing remote access products for Microsoft operating systems. It licensed source code from Microsoft and has been in partnership with the company throughout its history. Citrix came to prominence in the 1990s as a leader in thin client technology, purpose built for accessing remote servers. The company had its first initial public offering in 1995 and, with few competitors, experienced large revenue increases between 1995 and 1999.
The company acquired Sequoia Software Corp. in 2001 and ExpertCity, a provider of remote desktop products, in 2003. Between 2005 and 2012, Citrix acquired more than a dozen other companies, allowing it to expand into server and desktop virtualization, as well as cloud, Infrastructure as a Service, and SaaS offerings. In 2014, Citrix acquired Framehawk and used its technology to improve the delivery of virtual desktops and applications over wireless networks. In 2016, Citrix and LogMeIn announced a $1.8 billion product deal that would spin off Citrix's GoTo products into a new business entity, entitled GetGo, which would combine with LogMeIn's products.
Citrix is based in Fort Lauderdale, Florida and Santa Clara, California, with subsidiary operations in California and Massachusetts, and additional development centers in Australia, Canada, Denmark, Germany, India, and the United Kingdom. It currently services around 330,000 organizations worldwide. In 2014, the company was ranked 741 on the Fortune 1000. Citrix reported $3.28 billion in revenue and a net income of more than $300 million in 2015. In December 2015, Citrix employed approximately 9,500 people, but noted that its November restructure was due to eliminate nearly 700 full-time jobs. Former Microsoft executive Kirill Tatarinov became its CEO in January 2016.
Citrix was founded in Richardson, Texas in 1989 by former IBM developer Ed Iacobucci with $3 million in funding. Following its initial setup and development, Iacobucci moved the company to his former home of Coral Springs, Florida. The company's first employees were five other engineers from IBM that Iacobucci convinced to join his team. Iacobucci served as chairman of the company and Roger Roberts became the CEO of Citrix in 1990. Citrix was originally named Citrus, but changed its name after an existing company claimed trademark rights. The Citrix name is a portmanteau of Citrus and UNIX.
The company's first product was Citrix Multiuser, an extension of OS/2 developed over two years. Citrix licensed the OS/2 source code from Microsoft, and developed its own Independent Computing Architecture (ICA) protocol for Citrix Multiuser. Multiuser allowed multiple users working on separate computers remote access to software on a server, even from computers not built to run OS/2. Three days before the product launched in 1991, Microsoft announced they would be switching from OS/2 to Windows. The switch made Multiuser nearly unusable without significant changes to make it compatible with Windows or DOS. The company discussed closing in 1991, but investments from Intel, Microsoft and Kleiner Perkins Caufield & Byers among others, allowed the company to work on a new version of Multiuser.
Multi-Win version 2.0 was released in 1992. It was compatible with DOS applications and allowed up to five users. In 1993, Citrix released a new remote applications server, WinView, which had the ability to run DOS and Windows applications. By 1994, the company's yearly revenue equaled US$10 million.
Rise in popularity
Citrix had its initial public offering in December 1995. The company's share price doubled from $15 to $30. During the mid-1990s, Citrix became the leader of its growing industry with very few competitors, and the company's revenues doubled year over year between 1995 and 1999.
In 1997, during negotiations to extend licenses of Windows NT 4.0 source code to Citrix, Microsoft stated it would develop its own competing software to WinFrame. Citrix stocks dropped 62 percent after the announcement. Following weeks of discussions, Iacobucci was able to persuade Microsoft to agree to license Citrix technology for Windows NT Server 4.0, which resulted in Windows Terminal Server Edition in 1998. This agreement allowed Citrix to keep its position in the marketplace and be NT 4.0 compatible. Citrix also earned $75 million through the agreement, along with a royalty arrangement that was valued at approximately $100 million.
Citrix released MetaFrame 1.0 in conjunction with Terminal Server Edition. Due to weaknesses in Microsoft's Remote Desktop Protocol (RDP), Terminal Server Edition worked best using the ICA protocol developed by Citrix and found in MetaFrame. This meant that Citrix technology was purchased and installed on most machines running Terminal Server Edition.
In 1997, the company opened a new headquarters in Fort Lauderdale, Florida. It also opened offices in Sydney, London and Paris that same year. In 1998, Mark Templeton became the CEO of Citrix after serving as vice president of marketing. Also in 1998, it licensed its ICA protocol to IBM and Key Tronics. Citrix licensed its ICA protocol to Motorola for use in digital wireless handsets in 1999.
During 1999, the thin-client model Citrix used became a software trend and the company's customers increased to 15 million. Major clients included Sears, AT&T, and Chevron. A sudden drop in stocks in 2000 led to Iacobucci leaving the company and CEO Mark Templeton being demoted to president and senior executive officer. Templeton was later reinstated in 2001.
In 2001 Citrix acquired the Sequoia Software Corp. for $185 million. That same year it released MetaFrame XP, a new platform using MetaFrame technology. This was later rebranded by Citrix as Presentation Server, in 2005.
Citrix acquired ExpertCity, a provider of remote desktop products, in December 2003 for $225 million in cash and stock. The acquisition was the largest for the company up to that date. Through the acquisition, Citrix gained ExpertCity's existing products GoToMyPC and GoToAssist, and ExpertCity became the Citrix Online division of the company. In 2004, the company introduced Citrix GoToMeeting.
Between 2005 and 2012, the company acquired over a dozen companies that allowed them to expand in new markets. Citrix acquired acceleration hardware maker NetScaler in 2005, which allowed the company to offer optimized application delivery. The company entered the server and desktop virtualization market with the purchase of XenSource in August 2007. Citrix expanded cloud and Infrastructure as a Service (IaaS) offerings in August 2010 with the acquisition of VMLogix. In February 2011, Citrix entered the European Software as a Service (SaaS) market with the acquisition of Netviewer.
The company became a leader in IaaS after the acquisition of Cloud.com, provider of cloud infrastructure for companies, in July 2011. Citrix began offering VDI-in-a-box to small and medium businesses with the acquisition of Kaviza in May 2011. The company acquired technology for cloud-based file sharing and storage through its purchase of ShareFile in October 2011.
In May 2012, Citrix acquired Virtual Computer, maker of intelligent desktop virtualization. The technology is used in the company's XenClient Enterprise edition. Citrix entered the mobile video and telecom markets in June 2012 when the company acquired ByteMobile. Also in 2012, the company acquired Zenprise. Zenprise's Mobile application management (MAM) technology was released as XenMobile in February 2013.
In 2007, the company opened a headquarters in Silicon Valley. In 2008, the company changed the name of its Presentation Server product line to XenApp. Also in 2008, Citrix announced an expanded alliance with Microsoft on desktop virtualization solutions. On January 29, 2009, Citrix announced that 460 employee positions would be cut, comprising 10% of its workforce. In August 2010, Citrix announced a partnership with Google to bring the company's products to Chrome OS devices.
Citrix acquired Framehawk in January 2014 in order to use the company's technology to improve the delivery of virtual desktops and applications over wireless networks, including cellular, where speed and quality may be poor. In May 2014, Citrix acquired Scalextreme to bolster its cloud capabilities for its core business unit of XenDesktop and Xenapp such as auto scaling, patching and automation of complex deployments from the cloud.
On January 29, 2015, Citrix announced that 700 full-time and 200 contractor positions would be eliminated. This constituted about 10% of its workforce. The cuts were expected to save between $90 and $100 million a year. Two hundred of the layoffs occurred in Fort Lauderdale, Florida, where the company is headquartered.
The company had 10,081 employees as of February 2015. In December 2015, Citrix employed approximately 9,500 people, but noted that its November restructure was due to eliminate nearly 700 full-time jobs.
Citrix reported net income of $251.7 million in 2014, down from $339.5 million in 2013. In July 2015, the company announced several changes to their Board of Directors including Robert Calderoni becoming executive chairman and adding Jesse Cohn, a senior partner of activist hedge fund Elliott Management. That same month the company announced that president and CEO Mark Templeton would retire after a replacement was found, and on October 21, the company named its executive chairman, Robert Calderoni, as interim president and CEO.
As of October 2015, Citrix announced that it is reviewing potential spinoff or sale options for its GoTo products, which include GoToMeeting, GoToWebinar, GoToWebcast, GoToTraining, GoToAssist and GoToMyPC.

The offerings include GoToAssist for remote IT support; GoToTraining, which supports online training; GoToMeeting, which facilitates online meetings; GoToWebinar for webinars and online conferencing; Podio, a cloud-based collaboration service; and OpenVoice, which provides audio conferencing.
The company's philanthropic activities include corporate giving—such as corporate donations of in-kind gifts—and employee match programs. Citrix provides discounted and donated products to non-profits and other qualifying organizations through TechSoup. In addition, Citrix employees are allowed to take two paid volunteer days each year and participate in the company's annual "Global Day of Impact"—an event that encourages Citrix employees to volunteer in their local communities.
Near its Fort Lauderdale headquarters, Citrix has provided business training to non-profit teams. In particular, the company helped a local non-profit organization launch a computer on wheels to offer training to low-income neighborhoods. In 2007, the company connected a Broward County, Florida neighborhood with Agogo, Ghana through donated technology and training. Using the technology, the "Cyber Sister Cities" work together to sell African organic honey in the United States. Furthermore, the company's Raleigh office began a program called "Project Code" in 2014, which leads youth from local Boys & Girls Clubs through coding exercises and teaches them about computer science.
In addition to its philanthropic activities, Citrix has donated some of its open-source technology to non-profit software organizations to continue its development and gain more contributors. Citrix gave Cloudstack to the Apache Foundation in 2012 and Xen hypervisor to the Linux Foundation in 2013.
