I’m a huge fan of 37Signals and have followed them ever since they were a usability company through their transformation into a product company. Anyway about a year ago I heard they were working on a CRM product called Sunrise, which they have apparently agonized over, scrapped, and reworked. I think we can safely assume that Highrise is the next instantiation of that product.

I heard about this through the webworkerdaily which has a pretty good write up about it. Love to hear peoples thoughts, I have yet to check it out.
