The Salesforce.com Culture
Salesforce.com operates very differently than most other companies I cover. It keeps most of the leaders it picks up from acquired companies, for example, and these leaders remain in charge of their business units. The leaders of IBM's acquired companies tend to split, and Oracle and SAP have mixed records on this front at best.
Benioff is also more immersed in scoping out and personally using state-of-the-art technology than any CEO I've encountered. Sit in on a Q&A and it's quickly obvious that he's a student of technology leadership and innovation. He's constantly trying to bring the best ideas into Salesforce.com -- not as an add-on but as part of the DNA of the company.
As this article points out, it's hard to create connective tissue between very different technologies -- like Force.com and Heroku, for example -- but Salesforce1 is an attempt to unify that's just getting underway.
