“Trust is paramount. You must find a partner who treats your resources and vision as their own.”
Craig Harris and Gareth Broekmann came together in 2014 to co-found Charles Square, with Barry Cohen joining in 2017. Their extensive knowledge of the finance sector and their internal values, culture, and ethos have been the driving force behind Charles Square’s growth and grab of the market share. Together the three entrepreneurs have been able to provide the finance sector with a level of service, knowledge, and expertise that they struggled to find at other Managed Service Providers whilst working in-the finance sector for the past 20 years. Now in its 6th year, the firm has been named the “Best Specialist Financial IT Support Provider – London”.
