These include Bytesquad – six top TikTok creators who lived and created from Europe’s first TikTok House during the first 2020 lockdown. Bytesized creators provide brands with direct connections to their hugely engaged Gen Z audiences. Brands can work directly with the Bytesized team, or Fanbytes clients can tap into the Bytesized managed talent at any point.

Fanbytes can name multiple high-profile clients, including Burger King, H&M, Samsung, Deliveroo, Clinique, Vestiaire Collective, McVitie’s, Ubisoft, and Universal Music Group.

They are also proud to have launched the Fanbytes Impact Fund in 2020. This is a £250K fund dedicated to helping black-owned businesses and black creators get to the next level.
