I interned at salesforce. They have quite a few products so its hard to say what is they do in one sentence. But their target market is basically enterprise, they provide cloud infrastructure, they provide employee performance app (work.com - previously was startup Rypple they acquired). Their core product is the CRM (customer relation management) which is not really CRM now but more of a platform that you can add 3rd party apps to (such as work.com). Other products is a yammer-like thing called chatter (not a fan of it) but they give it out as a freebie last i checked. Summed up, i would say they are like the iOS/appstore platform but on the cloud and only for businesses. So i can use it to track my customers then i can add an app that does appointment scheduling for me for those customers, for example.
