Marc BenioffIโve seen how important this concept is in business. To be truly successful, companies need to have a corporate mission that is bigger than making a profit.

By integrating philanthropy into our business model our employees feel that they do much more than just work at our company. By sharing a common and important mission, we are united and focused, and have found a secret weapon that ensures we always win.
