Salesforce.com
When Salesforce.com got into the online CRM business, it was 100 percent of the online CRM business. Today, there are tons of newcomers and latecomers to the party, but Salesforce started the party, and that is a fact that should always be remembered by those who are considering which CRM makes sense for them. With more than a decade of experience where other brands have months behind them, Salesforce has the corner on the online CRM market, and they deserve to have it. Their features and interface are built upon experience and not hunches, and their many thousands of clients are happy to use what Salesforce provides to them.
