Arun Maini (Mrwhosetheboss) Biography

Arun Maini, better known online as Mrwhosetheboss, is a British-Indian tech YouTuber from Nottingham. He rose from making early DIY phone videos to becomea

Early life and background

Arun Maini was born on 24 October 1995 in Nottingham, England, and grew up in the same city. He attended Nottingham High School from 2007 until 2014. From a young age he showed an interest in smartphones and technology; when he was 14 his brother gave him his first Android phone, and Arun began learning how to customize and optimize it. Those early experiments with software and performance would later shape the focus of his online work.

After finishing secondary school, Maini enrolled at the University of Warwick, where he studied economics. He completed his degree in 2017, graduating with a first-class honours bachelor's in Economics.

Career

Maini launched his YouTube channel, Mrwhosetheboss, with his first video on 22 April 2011. In the channel’s early phase he worked with what was available: devices he owned or items he could borrow, since he did not initially have industry contacts or financial backing to test new products. His format centered on practical tips, customization tutorials and reviews aimed at helping viewers get more from their phones.

A significant breakthrough came in August 2015 when a tutorial he posted explaining how to turn smartphones into hologram projectors reached a far larger audience than his typical uploads. At a time when most of his videos drew a few thousand views, that tutorial attracted hundreds of thousands overnight and later amassed millions of views. The spike in attention helped broaden his audience and accelerate the channel’s growth.

After finishing university Maini received a job offer from PwC, but he chose to continue focusing on his YouTube career instead. His decision paid off: Mrwhosetheboss reached 1 million subscribers on 15 February 2018. Since then Maini’s channel has become known for thorough smartphone reviews, explainers about new gadgets and formats, and opinion pieces on trends shaping the tech industry, such as the trajectory of foldable phones.

Maini has also collaborated with other prominent creators in the tech space, including India’s Gaurav Chaudhary (Technical Guruji) and Canadian creator Lewis Hilsenteger of Unbox Therapy. His channel blends hands-on testing with broader industry commentary and product guides.

Public profile

Arun Maini is frequently cited in mainstream outlets about his work on technology and consumer electronics. His coverage has included appearances and features on platforms such as The Huffington Post, The Daily Telegraph, Business Insider, Good Morning America, The 6:30 Show and BBC Radio. Those profiles reflect his position as one of the UK’s best-known tech creators and a recognizable voice on consumer tech topics.

Family and personal life

Maini comes from a family involved in the cosmetic industry: his father, Dinesh Maini, and his mother, Malti Maini, are listed with roles at cosmetic clinics, and he has two siblings, a brother named Karan Maini and a sister named Aanavee Maini. Public listings show that he is unmarried.
