Drift

Like Intercom, which is the darling of the startup set, Drift lets you communicate with site visitors in those cute pop-up windows that feature emojis, and in Drift’s case, a robot. But unlike Intercom, which only has a two-week free trial, Drift lets you run a barebones version for free on your site. That lets you test the concept for a much longer time.

Drift recently landed $60 million in venture capital, so a lot of money is riding on this company to provide a viable alternative to Intercom.
