For more than 20 years, David Lewis has been a pioneering innovator in online marketing, marketing automation, and CRM systems and has overseen marketing for some of Silicon Valley’s leading technology firms. His career journey began at Microsoft, where he played a key role in launching the company’s groundbreaking Windows operating system and Microsoft Office applications.  Later, he moved to Silicon Valley to work with game-changing companies like Farallon, Netopia, and Ellie Mae.

Throughout his career journey, David has been at the forefront of the major disruptive waves that have transformed how companies offer their products and services to customers: the Web, marketing automation, CRM, search marketing, and social media.
