Your landing page talks all about workflows, so I'm unclear how this meets your own stated goal of being focused less on workflows and more on helping the team close bugs faster. From reading your page, I don't see a single feature that isn't already in Jira. I also have no ideas why reminding people to do their work is an issue to be resolved by software - sounds like a cultural problem, not a tech problem.

In any case, I don't think your problem is that you are missing features. It is that you are aiming for table stakes, and aren't showing us anything new and exciting.

If you want to truly change how teams operate and present us with a new model for managing and closing bugs, then you need to live up to your own description, move away from workflows and "my bugs" listed on pages, and show us something completely new.
