Vertex42 - Origins

Vertex42 was originally an experiment and outlet for Jon to apply his love of both Excel and web design. His initial experience with Excel came from developing various engineering models and using VBA to automate them. As time went on, he created more and more spreadsheets for whatever need came his way, including calendars, budgeting, project planning, time tracking, loan calculations, etc. Jon left his engineering job in 2008 to work on Vertex42 full time. His brother, Jim, joined him on this quest by providing his expertise in graphic design.

The slogan "The Guide to Excel in Everything" refers to our goal of helping people achieve excellence as well as the fact that spreadsheets can be used for a lot more than just lists and numbers. Fans of Douglas Adams' book, The Hitchhiker's Guide to the Galaxy, will recognize that the number "42" has a special meaning.
