Congratulations on the product. I will suggest this to my colleagues at work. We're currently using Google Docs to share/work on knowledge and we're not happy with it. Although Google Docs style comments would be nice to have in the future.

Unfortunately your "Try it now for free" button doesn't seem to resolve at the moment.

I saw that you are supported by UnternehmerTUM and would be interested to hear about your experience. I am studying at LMU and I am currently in the process of starting my own gig. Especially the Techfounders program sparked my interest.

If you want to, you can also E-Mail me. My address can be found in my profile.
