Syndicate was born Thomas George Cassell on 23 June 1993 in Manchester, England, according to his Wikipedia biography. He attended Blue Coat School in Oldham before studying software development and video game design at Hyde Clarendon Sixth Form College in Ashton-under-Lyne from 2010, subjects that fed directly into the Let’s Play career he was already starting to build. He has a younger sister, Alice, and his family, based in Greater Manchester, later became directly involved in his business ventures. Cassell has been in a relationship with Lydia Hewitt-Lee since 2016, and the couple have two children together.

Cassell launched his main channel, TheSyndicateProject, on 3 September 2010, uploading commentary-driven Let’s Play videos built around Halo, Grand Theft Auto and, most prominently, Call of Duty: Modern Warfare 2 and the Zombies mode of Call of Duty: Black Ops, per Wikipedia. He kept to a demanding schedule of two videos a day through his early years, a consistency he later credited as essential to standing out in the crowded gaming-commentary space. Once the channel passed 500,000 subscribers he began adding Minecraft content alongside his shooter Let’s Plays, a pivot that broadened his audience considerably ahead of the channel’s rapid growth phase.

TheSyndicateProject reached 1 million YouTube subscribers in June 2012 and passed 1 billion total views by late 2013, milestones documented on Wikipedia. His Minecraft output, including the collaborative Trinity Island and Mianite storylines made alongside creators Jordan Maron (CaptainSparklez) and Sonja Reid, helped cement him as one of the platform’s biggest personalities of the era. The breakthrough carried onto the newer platform Twitch, where on 17 August 2014 Cassell became the first individual video game broadcaster to reach 1 million followers, a milestone certified by Guinness World Records.

Cassell holds multiple Guinness World Records accumulated over his career. Beyond being the first person to reach 1 million Twitch followers, he and fellow YouTuber Dan TDM set a record for most goals scored in a single game of Rocket League by a team of two, netting 11 goals at the Insomnia gaming festival in December 2015, according to Guinness World Records’ coverage of the event. In September 2016 he was presented with a further certificate at Legends of Gaming Live recognising his Twitch channel as the most-followed on the platform at the time, with 2,457,382 followers, as reported by Guinness World Records.

In 2017, Forbes included TheSyndicateProject among its World’s Top 10 Gaming Influencers, a list built with analytics firm Traackr to rank creators by reach, audience size and engagement, as covered by CEOWORLD Magazine. His Forbes profile describes him as a Manchester-based digital content creator who amassed more than 10 million YouTube subscribers at his peak. He was also nominated for “YouTube Gamer” at the 2012 Golden Joystick Awards, for “Best British Vlogger” at BBC Radio 1’s Teen Awards in 2014, and for the Gaming category at the 2017 Shorty Awards.

Cassell’s highest-profile paid arrangement became the subject of a formal government investigation. On 7 September 2017, the Federal Trade Commission announced a settlement with Cassell and fellow YouTuber Trevor “TmarTn” Martin over their promotion of the CSGO Lotto gambling website, which they jointly owned without disclosing that relationship in their videos, and which they allegedly paid other influencers to promote without disclosure requirements. No financial penalty was imposed, but Cassell agreed to ten years of FTC compliance oversight, with future violations carrying fines of up to $40,654 each. Away from that case, his more conventional sponsorship work included a partnership with Activision to showcase the “Gunfight” mode of Call of Duty: Modern Warfare on Twitch in 2019.

Cassell co-founded the talent and entertainment company 3BlackDot in 2013 alongside fellow creators Evan Fong (VanossGaming) and Adam Montoya, along with two former Machinima executives, per Wikipedia. That same month, September 2013, he founded the apparel brand Syndicate Original, registered with UK authorities as Syndicate Original Limited, company number 08679880, according to Companies House, which lists Cassell as holding a 100% shareholding and serving as the company’s director. The brand is run day to day out of Greater Manchester by his family, with his sister Alice serving as chief operating officer. He also signed to the Jetpak multi-channel network in November 2014 and released a 12-track music compilation, “Sounds of Syndication,” through the Heard Well label in May 2016.

The best-documented account of Cassell’s living situation dates to his teenage years, when he and his father, who works as a construction project manager, purchased and renovated a property near the family home in Greater Manchester into an extensive custom gaming setup, as described by Streamerpedia. No deed, mortgage filing or purchase price for that property, or for any later residence, is publicly documented, and HMW was not able to verify claims circulating on lower-quality aggregator sites about a current Los Angeles mansion or a luxury car collection, so those figures are not counted here. His clearest documented major asset is his 100% ownership stake in Syndicate Original Limited, the apparel company confirmed by Companies House above.
