I have to be honest here, I hate signing up to test a product more so for invite on beta. Over the years of building online application I found out that is the case for a lot of people. You may want to consider providing a demo kinda open interface for your app.
Yes thanks for the comment. Eventually I'm going to have a test account that people can use. The issue is that I'm 100% tied to another application so I have to be careful with the data / functionality I use. They do have a sample account though.
