Foundations Built on Collaboration

Thames Systems was founded in 1996 by Stewart Kirkpatrick, originally formed as a limited company vehicle for Stewart and a group of trusted friends and colleagues. The aim was to support one another in contract work and create a platform where skilled professionals could work together, share opportunities, and deliver quality outcomes.

From the very beginning, the business was built on collegial spirit, mutual respect, and professional collaboration, values that continue to shape Thames Systems today.

Launch of T100

Thames Systems launched T100 in partnership with a global clearing firm to solve the increasing complexity of KYC and AML obligations.
