Ray Ozzie and Larry Moore both credit Sheldon Laube as the main reason for Lotus Notes initial acceptance and success. Sheldon was Price Waterhouse's first CIO, responsible for improving client services through technology. He purchased 10,000 units the day before the official product release. Until mid-2012, he was Chief Innovation Officer for the PricewaterhouseCoopers (PwC). He continues this work now as a consultant for various large enterprises across the globe.
