Arun Rupesh Maini (born October 24, 1995), better known as Mrwhosetheboss, is a British YouTuber who is best known for his technology-related content. His two YouTube channels have collectively earned over 25 million subscribers and 9 billion views.

Early life
Arun Rupesh Maini was born on 24 October 1995 in Nottingham, England and is of Indian origin. His mother is from India, and moved to the UK when she was 15. Maini's father is from Leicester, England. As a child, he attended two schools. On weekdays, he would attend a regular English school, and, on weekends, he would attend a Hindi school, in order to learn Hindi. He was educated at the fee-paying Nottingham High School; after completing his GCSEs, he studied economics at the University of Warwick in Coventry, England.

Career
He started uploading video game content to YouTube. When he was 14 years old, his brother gave him his first smartphone, a ZTE Blade. Maini made a video about it, which did much better than he expected. From there, he turned his attention to creating videos about smartphones, which ultimately led to the trajectory of his channel.

When Maini was studying at the University of Warwick in the United Kingdom, he was on an economics track. During the course of his studies, he had an internship at Pricewaterhouse Coopers, an accounting firm in London. He considered these eight weeks "rather mundane and boring". When there, Maini would often complete his work "really quickly" and begin jotting down ideas for new YouTube videos to be recorded that evening. At the conclusion of his internship with Price Waterhouse, Maini was offered an entry-level job that made a salary of about £35,000 (about $44,285). However, he turned down the job and prioritized his career on YouTube.

Maini initially focused on videos about smartphones, including smartphone reviews. However, as the channel's following expanded, he extended his video premises to covering laptops, cars, and even a vacuum cleaner. He has also made videos where he gives his opinions about topics such as manipulation of the media by tech companies and the metaverse. In 2015, Maini uploaded his first viral video which was a tutorial on creating a makeshift 3D hologram projector by crafting a pyramid composed of reflective material and placing it on a smartphone screen. The video received coverage from The Daily Dot and CNBC. The video is his second most viewed YouTube video, with his collaboration with youtuber MrBeast being the only video to have more views than his hologram projector video.

In May 2021, Maini signed with Night Media. In September 2022, Maini released a video claiming that Samsung phones may have problems with swelling batteries after he found that his Samsung Galaxy Note 8, Samsung Galaxy S6, and Samsung Galaxy S10 had all experienced the issue. Similar claims were corroborated in the video by YouTuber Marques Brownlee.

Personal life
Maini has restless legs syndrome. On 6 February 2023, he got engaged to his girlfriend, Dhrisha. He announced it in a YouTube video on 4 March 2023. The couple married on 8 June 2024.
