Our history

Whistlebrook has specialised in providing innovative, back office, software systems to the financial services sector since 1997. In that time, we have become a long-established and trusted supplier to the sector, with an ever-growing number of customers using our software. In the process, we have built up a very successful portfolio of software applications that can each be installed on their own, or as an integrated suite of two or more applications that can deliver extra benefits by sharing information.

Our customers range from investment management firms, through banks of varying size, to two of the three largest building societies.

Whistlebrook’s highly functional software can provide solutions for operational problems, insightful performance enhancement and financial analysis, leading to improved efficiency and profitability.

Whistlebrook develops all of its own software, in the UK, with major input from our customers. As a result our applications are specifically built for the financial services sector with tailored functionality, which really helps our customers to run their business more efficiently. It also means that we regularly enhance our software and introduce new applications following customer suggestions, our own on- going analysis, or regulatory changes
