Yep has several users, people I know personally have been beta testing it for a few months now. I haven't started marketing it yet because I have been dogfooding it since February in order to build exactly the CRM I personally want to use.

Also has > 800 automated feature tests, in app documentation, gone through security audits using tools like Zap, etc. I've built a lot of SaaS products over the years, and I'm building 6DollarCRM from the standpoint of having learned a lot of things the hard way. I'm currently working on data importers and browser extensions for easily adding new contacts.

Give it a spin and let me know what you think.
