Every employee has a voice at this San Francisco-based provider of hosted CRM applications. The IT department leverages company products like Force.com to create custom apps for their teams' projects. And the company's internal social network, Chatter, allows people to share ideas and collaborate with colleagues on different teams. Executives notice which employees are most active on Chatter, sparking discussions about new technologies and products, answering questions and challenging other staffers to take their ideas a step further. These employees are sometimes invited to sit in on executive meetings, share what they've been working on and weigh in on what is being developed behind the scenes.
