It offers a tailored suite of services—fund startup, accounting, valuation, reporting, and tax—designed to handle back-office tasks so managers can focus on investing. It operates in the financial services sector and functions as a partner for managers seeking operational efficiency and regulatory compliance support across various fund structures. A recent development is a 2026 partnership with Capis to launch a coordinated outsourced model that integrates trade execution with investment operations for buy-side firms. The firm was previously known as Tower Fund Services and is now branded as STP Investment Services.
