Mainspring prides itself on delivering bespoke services designed around the specific needs of each client. This covers the initial set up of the Fund; Investor KYC, set up and transfer agency; investor communications, delivering notices and reporting; managing drawdowns and distributions; banking and payments; the provision of standard quarterly, annual and tax reporting along with bespoke and ad hoc requirements; partner transfers and fund restructuring.
