Social Entrepreneurship[edit]

SOSV has taken an interest in furthering innovation in Education and Computing.

The Khan Academy[edit]

The O'Sullivan Foundation supports the Khan Academy,[30] the not-for-profit online learning platform whose goal is to change education for the better by providing a free world-class education for anyone anywhere. The Khan Academy is the brainchild of Salman Khan,[31] who brought the idea of educating young people, self-starters & people who learn at their own pace — online. The educational startup now counts over 2,600 videos in its library, with sessions or classes on everything from arithmetic to physics, including 211 practice exercises, to let students watch videos and learn at their leisure.


SOSV supports CoderDojo, a global network of clubs that teach young people in areas specializing in computer programming and computer technology. There are now dojos in 22 countries,[32][33] teaching 10,000 children to write computer code and programs each week.[34] Youth learn from one another about computer languages and tools including Xcode and CSS.[35] Founded by James Whelton and Bill Liao, a partner at SOSV, in 2011 as a not-for-profit organisation. The first dojo was held in the NSC (National Software Centre), Mahon, Cork on Saturday 23rd 2011. By February 2012, there were 12 dojos around Ireland and September 2012 saw the first CoderDojo open in Silicon Valley. At this point there are over 16,000 children worldwide learning to code every Saturday.[36]
