Seán William McLoughlin, born February 7, 1990, known by his online pseudonym as Jacksepticeye or just simply as Jack, is an Irish YouTuber who creates videos on video games, sketches and occasional vlogs. He previously resided in Athlone, Ireland, and currently resides in Brighton, England. He previously proclaimed himself to be the "most energetic video game commentator on YouTube". He currently has 27+ million subscribers, 12 billion+ views, and 4k videos as of May 2021.

Personal life

McLoughlin was born on 7 February 1990, in County Offaly, Ireland. His mother is Florrie McLoughlin and is Roman Catholic. He is the youngest of five siblings, having two older sisters, Allison and Susan, and two older brothers, Malcolm and Simon.

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

In the early 2010's, McLoughlin dropped out of college after two years whilst studying Music Technology in Limerick, Ireland. He finished college the second time around fall 2014, the same year that his channel reached 1 million subscribers.

Between 2013 and 2014, Jack had an unnamed Korean girlfriend. He started dating Danish YouTuber Wiishu (real name Signe Hansen) in July 2015 and she previously lived with him; the pair split in August 2018 after three years. Since December 2018, he is currently dating Dutch YouTuber Gab Smolders (real name Evelien Smolders).

On January 27th 2021, Jack's father passed away. He revealed in a 2019 Twitch stream that his father was moved into a care home. Jack has moved house on three occasions: from a cabin to an apartment in May 2014, to Brighton in May 2017 and to a different house in Brighton in April 2021.

Name origin

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 received 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".


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 originally wanted the channel to be dedicated to impressions.

Whilst playing Battlefield 3, Jack searched for tips online and came across LevelCapGaming. He was also a fanboy of Markiplier and PewDiePie, becoming part of his inspiration to start his own channel. Lacking friendships and living in a remote area, he turned to YouTube so he could create an online community, despite being pressed for time to make videos since he was also studying for exams in college. In September 2013, he entered PewDiePie's shout out competition and was one of several channels who won, where he went from 2,000 to 15,000 subscribers and pounced upon the opportunity to improve. Mark noticed Jack by writing on Twitter that he had entertaining videos, resulting in their first ever collaboration being "Gmod Sandbox w/ Markiplier | DON'T WORRY....WE'RE SCIENTISTS."

From 2012 until 2014 Jack lived beside his parents in a cabin, causing 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 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 his first editor. For the first time in five years in October 2017, there were no scheduled uploads for a week due to him touring with the Game Grumps.

Jack kick started 2018 with the motto, Positive Mental Attitude (abbreviated as PMA), which turned into a merchandise line released in August 2018. Between July and October 2018 he took an extended break to Los Angeles. His previous upload schedule was two videos per day seven days a week, although has since decreased beginning on July 20th 2018; in August 2019 he resumed his former schedule. Throughout 2020 his schedule became sporadic; in his end of year vlog 2020 Almost Made Me Quit Youtube he explained he developed health issues which took a toll. Because of this he's chosen to step back from his channel and release videos once every few days.

While his main focus is on game plays of a variety of different genres, from indie to horror to upcoming releases, he occasionally does vlogs and sketch comedy. He is known for his energetic and caring personality, but tones down to seriousness when something needs to be talked about. He has shown his appreciation for his fanbase multiple times, such as making a subscriber milestone video thanking them.

As Jack became more well known for his videos, he earned various opportunities worldwide, such as attending Indy Pop Con in 2015, Insomnia 62 in December 2015 in the UK and PAX East and PAX West from 2015 to 2019 in America. He dyed his hair green alongside Markiplier in September 2015 for charity. In July 2017, he co-hosted the D23 Expo Level Up! panel in California alongside YouTuber Strawburry17. Jack was a special guest and antagonist for Scare PewDiePie: Season 2, which was cancelled due to Felix making unintended jokes. In October 2017, he and the Game Grumps toured Europe for Ready Player 3. In March 2018 until November 2018, Jack embarked on his first solo tour How Did We Get Here?.

He was interviewed on The Late Late Show in Ireland on February 23rd, 2018. In May, Jack uploaded a video of him playing Deadpool with actor Ryan Reynolds. In October, he unveiled his and Mark's own clothing brand Cloak.

Announcement tweet

On April 7th 2020, he and 100 creators participated in the 'Hope From Home' initiative against the COVID-19 pandemic. Throughout 2018 and 2019, Jack and his fans have raised over $3.9 million for charity. On May 18th, 2020 Jack posted on Twitter "Might f*** around and release a coffee company soon!" The company was later named 'Top of the Mornin'. The launch was set for June 1st 2020 but was pushed back due to the pandemic; the official date was changed to June 15th 2020.
