Anyone interested in a startup2startup collab?

Hi makers and hunters! I'm working on a tool that can work on top of your SaaS app (perfectly if it’s a CMS or any managing system :-)) My tool cuts down the repetitive task of form-filling to a bare minimum. So it is pretty useful for web devs. It has some unique features as well: you can share it with your teammates and manage from UI easily. What I need to do right now is test my tool on as many web apps as possible. So, straight to the point, I'm looking for startup products we could use to do such tests. Your web app can appear in my tutorials, screenshots and case studies! If you’re willing to collaborate, comment or drop me a line maciek@fill.ly
