Roger Hart, a former trainee nurse, and Jack Hesketh, a UCL biologist working on his PhD, opened the first shop in October 2010. They were among the first London cafés to serve cold brew, matcha and guest espresso.
Square Mile Coffee Roasters is the main roaster. Four shops now trade: Store Street, Tavistock Place, Hammersmith, and Bishopsgate, which opened in January 2022.
