Whistlebrook Corporate Overview

Since our inception in 1997, Whistlebrook has been committed to delivering innovative software solutions to the financial services industry. In 2025, we proudly became an employee-owned business, operating as an Employee Ownership Trust (EOT). This model ensures that the people who know our products and customers best, our employees, have a direct stake in our success, strengthening our long-term commitment to customer service, innovation, and sustainable growth.

We believe that software innovators make the greatest impact when they collaborate. That’s why we work in close partnership with our clients to shape our growing software portfolio. Each module’s strategic roadmap is proactively developed with our customers’ evolving needs in mind.

Our sole ambition is to empower financial services businesses to focus on customer engagement, while our suite of integrated modules handles their regulatory reporting, financial accounting and forecasting, and financial risk management. Our software solution orchestrates data from core systems of record and customer engagement platforms into a consistent, unified view.

While there are many competitors, both large and small, none offer as comprehensive a suite of modules as Whistlebrook. We provide the financial services industry with a holistic view of their organisation, whether they are assessing their financial and risk position in the past, present, or future.
