Mainspring was founded in 2010 to provide an outsourced administration service to small and medium-sized private equity and venture fund managers in the UK, where few viable service providers existed. Following demand from our clients that operated EIS and other tax-based funds Mainspring became authorised by the FCA to act as a custodian in 2013.
Since then, Mainspring has built two administration businesses. The first, Mainspring Fund Services, focuses on accounting and administration for private equity and venture capital fund managers with LP funds. This has become one of the leading administrators in this segment of the market and it has since then expanded into a number of key jurisdictions to service larger LP funds. Secondly, Mainspring Nominees Limited, a leading custody business for fund managers offering managed account investments such as EIS funds, which with the acquisition of the Share Centre’s EIS Division in 2020, is now the largest provider in this market. This has been evolving to provide services to other managed account based investing into private assets.
We pride ourselves on the numerous awards and industry recognition we have received including the globally recognised FIS Impact award for innovation, and the EIS Associations Best Administrator award.
