de Havilands' Story
From 25 years of in-the-trenches experience developing Excel solutions for financial services, Marcus Syben, our Principal Consultant knew firsthand that small teams at the coalface often bear the weight of large, complex Excel processes.
It was Marcus' goal to change that, allowing small teams in financial services do more, in less time, with less errors and remove the drudgery from repetitive Excel tasks so they can add more value where it matters.
