Ask HN: Recommendations for combined CRM/support software?

Maybe this is more of a dream than a reality, but I am looking for software that can act as both a CRM (categorizing leads, people, keeping track of follow-ups) and support software. So at one glance, I could see every communication that my team has had with a person, since the beginning.

Right now, we are tracking this with email and Zendesk, and it's becoming cumbersome. Is something like this out there?
