David Den Boer

Chairman & Founder
David Den Boer founded Column5 Consulting in 2005. A dedicated professional services practitioner and entrepreneur, he has applied his significant technical delivery experience and broad experience providing solutions across a wide variety of industries — and raising the standards for what success means within EPM. As a founding principal with the launch of Column5, David sought to extend the focus of EPM beyond just implementing technology, assembling a team of business process visionaries and senior product talent with unmatched ability to deliver world-class EPM solutions.

Under David´s leadership, Column5 has evolved beyond its reputation for technically superior solutions to be an influential global provider of high—value EPM solutions. His prior experience includes consulting experience as Director of Services at OutlookSoft from 2000 to 2005.

Steve delivers a wealth of experience through his highly educational, consultative approach. His unique ability to partner with visionary executives from a who´s who of leading global organizations has played a vital role in helping them transform their companies to achieve new heights. Under Steve´s direction, Column5´s sales team focuses on educating clients to appreciate sources of value, rather than strictly emphasizing technical specifications.
