CRM packages on Rails

A client of mine just asked me to recommend some lead tracking/CRM
packages built on Rails. He’s just looked at SugarCRM and seemed to be
impressed with it for whatever that’s worth.

So far, I’ve found:

Highrise from 37 Signals (
LeadsOnRails from Synap (

I looked at the Cadmio Web site and the product is still under
development. doesn’t come up.

Any others that anyone can recommend?
