The original company was established in 1999 as the regulated Gibraltar member firm of Grant Thornton International.  

In 2006, the Fund Services firm was established to provide regulated fund administration services to a variety of funds.  This became the Grant Thornton Corporate and Fund Services group.

On 30 November 2017 the group was acquired by the Gibraltar Stock Exchange Group and formed part of the ecosystem being built by GSX. The group was renamed Juno Services.

On 23 December 2020, the GSX Group decided to divest all non-core businesses to focus its resources on the execution of its capital markets vision and Juno Services Group of Companies was acquired from GSX in a management buy-out.
