How Finstack came to exist

As a former CFO in the fast-paced world of scale-ups, I have personally experienced the challenges and inefficiencies that finance teams face, particularly in the realm of financial consolidation and planning.

Believe me, I understand the frustrations of managing complex financial data, reconciling accounts across subsidiaries, and the stress that accompanies the month-end close.

When I was working at a company with 150 people on its payroll that, overnight, lost over 90% of its revenue due to COVID, it became clear to me how broken the process of reporting & financial planning for SMEs really is.

That there was a pressing need for a better solution – one that would streamline financial processes, reduce manual workload, and alleviate the burdens faced by finance teams.

It was from this realisation that Finstack was born.

At Finstack, our mission is simple yet powerful: to transform the world of finance. We are committed to providing innovative financial technology that enables finance teams to be strategic partners within their organisations.

"Our platform offers automated consolidation, real-time insights, and a user-friendly interface, empowering finance professionals to work more efficiently and effectively."

Our vision? We want to make finance easy, actionable, and collaborative, giving finance teams the tools and insights they need to add real value to their organisations. The goal is to create a world where finance is not just about numbers, but about strategy, insights, and collaboration.

With Finstack's cutting-edge technology, you will have all the tools you need to elevate your finance department to new heights.

I invite you to join us in redefining this financial landscape. Let's work together to create a future where finance teams are empowered to drive change, make informed decisions, and become valued strategic partners in their organisations.
