In 1995, Shuttleworth founded [[Thawte Consulting]], a company specializing in [[digital certificate]]s and [[Internet security]].

In the 1990s, Shuttleworth participated as a developer of the [[Debian]] [[operating system]].<ref>{{Cite web |title=Developers LDAP Search |url=http://db.debian.org/ |access-date=20 April 2010 |publisher=The [[Debian]] Project |quote=User Mark Shuttleworth (login "marks", PGP/GPG key id 0xD54F0847)}}</ref> According to the Official Ubuntu Book, he was the first to upload the [[Apache HTTP Server]] "into the Debian project's archives".<ref name="histubuntu"></ref>

In 2004, he returned to the free-software world by funding the development of [[Ubuntu (operating system)|Ubuntu]], a [[Linux distribution]] based on Debian, through his company, Canonical Ltd.<ref name=":0" />

In 2005, he founded the Ubuntu Foundation and made an initial investment of US$10 million.

On 17 December 2009, Shuttleworth announced that, effective March 2010, he would step down as CEO of Canonical to focus on product design, partnerships, and customers.

==Spaceflight==
[[File:Mark Shuttleworth NASA.jpg|thumb|Shuttleworth on board the International Space Station]]

Shuttleworth gained international attention on 25 April 2002, becoming the second self-funded space tourist (after [[Dennis Tito]] in 2001) and the first South African in space.{{Efn|name="african"|Shuttleworth is the first citizen of an independent African country to go into space.

Two days later, the [[Soyuz spacecraft]] arrived at the [[International Space Station]], where he spent eight days participating in experiments related to [[AIDS]] and [[genome]] research. On 5 May 2002, he returned to Earth on [[Soyuz TM-33]].
