Cogmap

From CogMap:

CogMap is the Wikipedia of organization charts. It is an organization chart wiki that lets you see, edit, and create organization charts for companies on-line. CogMap is a tool for sales people, entrepreneurs, and recruiters to understand organizations and keep information up to date. If you are like us, you had some of these things happen to you when you worked at a company without a published organization chart and had no idea who worked for anyone else, tried to figure out who to call at a company and come up empty, bought a list of people to call and had all the information be wrong, and met people that all had different titles and been unable to tell who was the decision-maker in the room.
