One of the compelling aspects about Salesforce is the vast amount of integrations it has. It can sync with Facebook, LinkedIn, Google and many more.
Salesforce have also broken out their products by function like CRM, Marketing and Sales and of course each of their products integrates with each other too.
This huge network is very impressive and it appears to be an effective business strategy.
Why?
Because in order to see the full benefits of Salesforce you need to incorporate more Salesforce products into your systems and the more Salesforce you incorporate the more locked in you get and the harder it becomes to leave.
