We agree more than it might look.
1. Contact mgt is a necessary function in CRM. It's essentially merging into email and Soc Media message capture and management. Contatta has an excellent interface to that need. You can't really do any other CRM functions without that
2. It wouldn't be outrageous to say that 85% of CRM usage is contact management. That doesn't really mean that 85% of people only use CM. CM is a necessary route to get at the opportunity and support management. That said, many CRM's, and especially salesforce, force a user to deal with more application overhead than is really necessary.
3. There is a HUGE difference between the way an in-office salesperson and an outside rep uses CRM. As in, ""the outside guy uses is far, far less."" Robust mobile clients, with voice rec, will likely change this. Automatically channeling relevant social data into the contact/account records will also affect this. But the focus of both types of reps is to make sales and to do this in a way that enables forecasting and exception management. So, it can't be just contact management, but the non-CM operations are certainly a minority.
4. It's hard to imagine Contatta reaching a size enabling an IPO. (I am using Zoho as an anchor in this mind experiment.) Sullivan't no idiot (although I'm not convinced he has the skills to get beyond the startup phase.) So you know they must think that acquisition is their investor's likely exit strategy.
Who would buy it? One possibility is an outfit like Infor that doesn't really have a decent CRM for its ERP systems, but then you run smack into the problem of whether Contatta actually fit the needs of those customers.
Another possibility is an existing CRM, such as salesforce as you mentioned. But this would only happen for the UI, as I don't see complementary tech lurking within Contatta. And that only makes sense if the UI turns out to be really hard to do.
Which leads to my key question about Contatta. Is this really a radical offering that buys it several years head start before others can copy enough of it to level the playing field, or is the UI just a creating implementation of existing technology that can be readily copied by a CRM firm that knows what it's doing in state of the art web UI?
Right now, I think it's the latter. But it is early.
