He previously resided in Ireland, and now currently resides in Brighton, England. He moved to L.A. for two months from July 12th 2018 until August 23rd 2018. He proclaims himself to be the "most energetic video game commentator on YouTube". He currently has 19.6 million subscribers, 9 billion+ views, and 3.8 thousand+ videos as of July 2018.

Personal life

McLoughlin was born on 7 February 1990, in Athlone, Ireland, in Co. Westmeath. His mother is Aideen McLoughlin (b. 1969) and is Roman Catholic. He is the youngest of five siblings, having two older sisters and two older brothers, one of whom is Malcolm, a writer.

He was a former drummer of an indie heavy-metal band named Raised to the Ground. In the late 2000's, he graduated high school with a degree in Music Technology.

In the early 2010's, McLoughlin dropped out of college after 2 years. However, after meeting a person on Interpals, he decided to study English. He finished up college around autumn 2014, the same year that his channel reached 1 million subscribers.

He started dating Danish YouTuber Wiishu around early 2015 and she is currently living with him.

The Jacksepticeye Foundation was established on January 30, 2017.

Origin of the Name

In Ireland, "Jack" is a common nickname for the name "Sean", and both his mother and friends called him this. His friends started calling him "Jacksepticeye" after a football accident where he got an eye laceration from a friend's glasses. According to him, the wound bled for quite some time and became infected after a few weeks, hence the name "Jacksepticeye". (Septic is a medical term referring to a systemic infection).

Channel history

Jack created his YouTube channel on February 24th 2007, although he didn't start making his own videos until November 2012, his very first upload being a Metal Gear Solid 4 impression on Solid Snake. According to Jack in a 2017 video, he explained he originally wanted the channel to be dedicated to impressions.

Whilst playing Battlefield 3, Jack searched for tips online and came across LevelCapGaming. Jack was also a fanboy of Markiplier and PewDiePie, becoming part of his inspiration to start his own channel. After finding out that making your own content on YouTube was a "job", he did just that, despite being pressed for time to make videos since he was also studying for exams in college. Mark noticed Jack by writing on Twitter that he had entertaining videos and Felix gave him a shout out in a competition.

From 2012 until 2014 Jack lived beside his parents in a cabin in Co. Offaly, resulting in issues with his internet affecting his uploads. He had to use a camera as his microphone and attempted to hide his Irish accent by pretending to be American for fear of being made fun of. In his May 2018 livestream, Jack revealed that he was on benefits at that time and lacked friendships.

In 2014, he moved to an apartment in Athlone for better internet access. He graduated from college that same year and earned a degree in Hotel Management. In 2016, Jack hired Robin as an editor.

Jack mainly focuses on game plays on a variety of different games, from indie to horror to upcoming releases, and occasionally vlogs. He is known for his loud, bouncy but caring personality and constant positivity, but tones down to seriousness on some occasions when something needs to be talked about. He shows his appreciation for his fanbase multiple times, such as making a subscriber milestone video thanking them and more recently Septic Art, admiring fans creativity on their works.

Video schedule

Jack uploads two videos daily, at 17:00 and 20:00 (upload times differ depending on the viewer's time zones), but there have been some instances where his schedule has been interrupted:

  • For the first time in five years, between October 4th 2017 until October 20th 2017, there were no uploads due to Jack touring with the Game Grumps.
  • December 25th and 26th 2017 had no uploads because Jack wanted a break.
  • April 5th until April 11th 2018 there were no uploads due to Jack touring.
  • When Jack livestreams for charity, there are no videos during the allotted time since Jack streams from 4 p.m. until 1-2 a.m.
  • Beginning May 23rd 2018 until June 7th 2018, Jack uploaded one video per day due to touring Canada and the West Coast of America.
  • June 23rd 2018 until June 25th 2018, there were no uploads since Jack was unwell.
  • July 12th and July 13th 2018 had no uploads because Jack wanted a break and moved to L.A. for two months.


As Jack got more well known for his videos, he earned various opportunities worldwide, such as attending Indy Pop Con in 2015, Insomnia 62 in Birmingham, UK in December 2015 and PAX East and PAX West every year in America. He dyed his hair green alongside Mark in September 2015 for charity. In March 2017, he co-hosted the D23 gaming event in California alongside YouTuber Strawburry17. Jack was a special guest and antagonist for Scare PewDiePie: Season 2, which was eventually cancelled due to Felix making offensive jokes. In late September 2017, Jack began his very first tour How Did We Get Here? and in October 2017, he toured Europe with the Game Grumps for Ready Player 3.

He was interviewed on the Late Late Show in Ireland on February 23rd 2018 and met some fans there. In May 2018, Jack uploaded a video of him playing Deadpool with Ryan Reynolds. Over the course of five charity streams so far in 2018, Jack and his fans have raised over $752,000 for charity.
