Excel Solutions with Real Impact
At de Havilands, we believe Excel should be the tool that brings financial services teams to the next level—not something that holds them back. In a field where time is money, our mission is simple: to free finance professionals from the “soul-crushing” manual tasks they deal with every day so they can focus on what really matters—getting results.
Whether you work in asset management, banking, FX trading, private equity or one of the many other financial service niches, we’re here to make your work life smoother and more efficient.
What We Stand For
We know firsthand that small teams often bear the weight of large, complex Excel processes, and it’s our goal to change that. Our approach is personal, hands-on, and focused on relationships. We’re not just about solving Excel issues; we’re about understanding your unique challenges and finding ways to streamline the entire workflow.
Why de Havilands?
What makes us different? For one, experience—Marcus Syben, our Principal Consultant, has been working with Excel in the financial sector for over 25 years. He’s been awarded Microsoft’s MVP status for Excel, which just means he knows his stuff when it comes to helping clients get the most out of this powerful tool.
With de Havilands, you’re not getting a one-size-fits-all solution. Instead, we bring:
Marcus Syben
Principal Consultant & Microsoft Excel MVP (Most Valued Professional)
Meet Marcus, Principal Consultant
Marcus has spent the last two decades providing Excel solutions to financial services firms worldwide, from Australia to London. His work includes a whopping £170 million reduction in Risk Weighted Assets (RWA) for one of Europe’s largest investment banks—a project that brought an estimated £11 million P&L boost. But Marcus will tell you the best feedback comes from team members who are relieved to have fewer “soul-crushing” hours spent on repetitive work.
And if you’re part of the Excel community, you might recognize Marcus from his clear, helpful advice on online forums. Tom C., one of his community followers, once commented, “Kudos to Marcus Syben. That’s the most elegant, well-structured explanation I’ve seen for this sometimes maddening function!”
Client Success Stories
We’re proud to work with clients who’ve valued our approach and solutions. Jamie C., a former client, once mentioned, “I didn’t appreciate how easy it was to work with Marcus until I had to work with other developers.” Another client, Frank F., put it this way: “Very rarely can someone interpret ideas so well as Marcus has.”
