About PerfectXL

Our team

Located in Amsterdam and Delft in the Netherlands, our team members each specialize in different disciplines. There is, however, one important thing that connects us: we all love spreadsheets!

Passions, work ethic,
and love of great software

One of the many things that binds our team together is a love for board games. Figuring out the intricacies in human interaction and discussing optimal strategies is something that carries over into our work style perfectly. We stay competitive, focused, and determined while also lifting each other up, discussing optimal strategies, and enjoying ourselves. As a real team each individuals victory is a victory for all of us as we strive to point out each others strengths, and support each other in our weaknesses. Our collective goal is to make great Excel related software for great clients that will truly see and experience the value of PerfectXL.
