Jacksepticeye, the energetic Irish YouTuber known for his high-volume commentary and infectious positivity, is currently 36 years old. He was born Seán William McLoughlin on February 7, 1990, a date consistently verified across biographical databases and major publications including Forbes . This makes him one of YouTube’s most enduring creators, having built an empire over more than a decade of consistent content creation.
The man behind the “Top of the morning” greeting grew up in Cloghan, County Offaly, Ireland, before relocating to Athlone and eventually settling in the United Kingdom . His journey from a rural Irish upbringing to international stardom is a testament to the transformative power of digital media. Today, his main channel boasts over 31 million subscribers and nearly 18 billion total views, making it the most subscribed channel originating from Ireland .
The Origin of a YouTube Icon
McLoughlin created his YouTube channel on February 24, 2007, but did not begin uploading videos until November 2012, with his first upload being a Metal Gear Solid 4 impression of Solid Snake . He originally wanted the channel to be dedicated to impressions, a far cry from the gaming and variety content that would eventually define his career. Lacking friendships and living in a remote area, he turned to YouTube to create an online community, despite being pressed for time as he was also studying for exams in college .
The nickname “Jack” comes from his childhood, as in Ireland, another name for Seán is John, and a common nickname for people called John is Jack . The term “SepticEye” originated from a school injury where he sustained a severe infection to his eye, leading a friend to call him “Jack Septic Eye” after learning that his mother called him Jack . He would later adopt this unusual moniker as his online username, creating a brand that would become globally recognized.
In his early videos, McLoughlin spoke using an American accent out of worries that no one would take an Irish YouTuber seriously . Eventually, he embraced his natural Irish accent, which has since become one of his most recognizable trademarks. He initially lived beside his parents in a cabin, which caused issues with his internet connection affecting his uploads, and he had to use a camera as his microphone .
The Breakthrough and Rise to Fame
The turning point in McLoughlin’s career came in September 2013 when he entered a shout-out competition hosted by PewDiePie, then the world’s most popular YouTuber . He was one of several channels who won, and his subscriber count skyrocketed from 2,000 to 15,000 almost overnight. He pounced upon the opportunity to improve, dedicating himself fully to content creation. Shortly after, Markiplier noticed Jack by writing on Twitter that he had entertaining videos, resulting in their first collaboration being “Gmod Sandbox w/ Markiplier” .
In 2014, McLoughlin moved to an apartment in Athlone for better internet access and graduated from college that same year, earning a degree in hotel management . He had previously attended college for Music Technology but did not finish, making the hotel management degree a significant achievement . By this point, he was uploading two videos per day, seven days a week, a grueling schedule that would continue for years.
McLoughlin’s influence grew to the point where he received recognition from major media outlets. In September 2017, he was included in Forbes’s list of the Top Gaming Influencers . The following year, Forbes estimated his earnings at $16 million, ranking him the eighth highest-paid YouTuber . In 2019, he was again estimated to be the eighth highest-paid gamer by Forbes, with earnings of $11 million . His consistency has remained remarkable, with Forbes ranking him at number 35 on the 2026 Top Creators list with estimated earnings of $18 million .
Career Milestones and Major Projects
Throughout his career, McLoughlin has expanded far beyond simple gaming videos. In October 2018, he and Markiplier launched Cloak, a clothing brand aimed at gamers . The brand later welcomed Twitch streamer Pokimane as a third partner and creative director in June 2020 . In 2020, he also created his own coffee company, named Top of The Mornin’ Coffee, further diversifying his business portfolio .
McLoughlin toured throughout September and October 2017 in the United States with his How Did We Get Here tour, and later in the UK and Europe with the Game Grumps on their Ready Player 3 tour . The How Did We Get Here show consisted of a biographical retelling of his childhood in Ireland to his rise as a popular YouTuber, alongside segments in which he would play games with his fans . In February 2018, he released dates for a US and Canada run of the tour, and that July, he performed the show at the Just for Laughs comedy festival in Montreal .
In 2021, McLoughlin appeared as a cameo in the movie Free Guy, starring Ryan Reynolds . He provided director Shawn Levy with advice on how to make the film authentic to video game culture, and Reynolds had previously appeared in a video of McLoughlin’s where they played the video game Deadpool together . In 2025, he played the supporting character “Punch Up” in a voice role for the video game Dispatch, starring Aaron Paul, and in 2026 he appeared in Markiplier’s self-funded horror film Iron Lung .
Philanthropy and Mental Health Advocacy
McLoughlin has become known as one of YouTube’s most prominent philanthropists, with Business Insider calling him “one of YouTube’s most well-known philanthropists” . He has raised millions for charitable causes through his livestreams, particularly for mental health organizations. His charity streams have become legendary within the YouTube community, with fans donating substantial amounts to support causes he champions.
In 2018, McLoughlin kickstarted a new motto, Positive Mental Attitude, which became a merchandise line released in August of that year . This emphasis on mental health awareness has been a recurring theme throughout his career. In a video released on July 2, 2020, McLoughlin announced he was taking a month-long break due to mental health concerns and the situations going on with YouTube and Twitch, explaining that he did not want to upload daily content because he needed to, and was taking a month off because he did not want to make YouTube videos at that time . He returned to his YouTube channel on August 11, 2020, with a livestream announcing his return to uploading content .
McLoughlin has been open about his personal health journey as well. On March 9, 2022, he was diagnosed with ADHD, and on November 28, 2024, he tweeted that he had also been diagnosed with autism after having an assessment for it weeks prior . In March 2025, his doctor informed him that his cholesterol was getting very high, prompting him to diet and exercise, and he successfully reduced his weight from 80 kilograms to 70 kilograms by June 2025 .
Personal Life and Relationships
McLoughlin’s personal life has occasionally been in the public eye. From early 2015 to October 2018, he was in a relationship with Signe Hansen, also known as Wiishu, a Danish artist who often posted fanart of him on her Tumblr . They met because she was a fan of his, started talking on Tumblr, became friends, and eventually entered a romantic relationship . Signe moved in with McLoughlin, and the two lived together in Brighton, UK . On October 9, 2018, McLoughlin announced that he and Signe had broken up, stating that it was not an easy decision to make .
On March 15, 2019, it was announced via photos on their respective social media accounts that McLoughlin is in a relationship with Dutch YouTuber Gab Smolders, formerly known as GirlGamerGab . She is also a content creator, and the two have appeared together in various videos and social media posts.
Despite his overwhelming popularity, McLoughlin has remained grounded. He admits that he does not describe himself as a celebrity or famous, as those terms make him feel uncomfortable . He still often interacts with fans, be it on Tumblr reblogging fanart and adding thank you comments, or responding to replies on Twitter . He largely interacts with his community and has definitely shown he cares about his audience.
The Future of Jacksepticeye
At 36 years old, McLoughlin shows no signs of slowing down. In a July 2022 episode of the Trash Taste podcast, he said that he would likely not continue streaming on Twitch because he wanted to focus more on his edited YouTube content . This strategic decision reflects his understanding that long-form, carefully produced content may have more longevity than the ephemeral nature of live streaming. In 2023, he and Chris Redd co-hosted The Gamer and the Mouth, a show featuring gaming creators and comedians in a mixed gaming and comedy event .
McLoughlin’s ability to adapt and evolve has been key to his continued success. His upload schedule has decreased from two videos per day to one, and occasionally he resumes his former schedule . While his main focus remains on gameplay videos spanning a variety of 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 addressed .
His fans, who have grown up alongside him, remain fiercely loyal. The 36-year-old Irishman has transformed from a shy college student hiding his accent to a global icon who has appeared in Hollywood films, launched successful businesses, and raised millions for charity. His age is not just a number but a marker of longevity in an industry where creators often fade after a few years. For over a decade, Jacksepticeye has remained relevant by staying authentic, adapting to change, and never forgetting that his success ultimately comes from the community that has supported him from the beginning.Is Jacksepticeye older than Markiplier?
