Management Team

David Macdonald, President

Mr. Macdonald has founded a string of successful high tech startups that have created dozens of bestselling software products. At Vertex, Mr. Macdonald has overseen the development of a number of Web-based software applications, including the popular online driving course sold to DefensiveDriving.com. Prior to founding Vertex, Mr. Macdonald founded Arion Software, a home productivity software company that created the MasterCook series, the world's best-selling cooking and nutrition software. The MasterCook series featured numerous co-branded bestsellers, including the Betty Crocker, Cooking Light, Jenny Craig, and Graham Kerr digital cookbooks. Arion was sold in 1995 to Sierra On-Line, at the time the world's largest maker of PC game and home software titles. Before founding Arion, Mr. Macdonald co-founded Styleware, which pioneered GUI and integrated software for Apple II computers. Styleware was sold to Claris Corporation, Apple Computer's former software subsidiary. Styleware's final product, AppleWorks GS, was the #1 best-selling software program in early 1989, and the Styleware team went on to create the best-selling integrated software package, ClarisWorks, for Macintosh and Windows (now sold by Apple under the resurrected name AppleWorks). Mr. Macdonald is also founder and president of TeamSys Corporation and co-founder of Synk, Inc.
