Great idea. There are few things more frustrating in business than unproductive meetings, and so often they could easily be fixed with better preparation, focus during the meeting itself, and/or follow-up. This seems like the kind of tool that could genuinely help and could pay for itself very quickly while still generating plenty of returns for you.

I have two hopefully constructive and slightly meta suggestions:

1. Your tour page could benefit from some TLC. I looked at it on a large monitor, and it was so spaced out and the text so large and poorly rendered that it was actively unpleasant to read through. I’m happy to give more specific feedback if it would be useful. (I’ve just realised that despite being interested in your project and having reached the end of that page, in the time it took to write this comment I have already forgotten almost everything it said except for a couple of features I guessed would be there anyway.)

2. You’re writing a tool where business people are presumably going to discuss work, potentially including all kinds of sensitive information about current status and future plans. I lost track of how many deal-breakers your current privacy policy contains in that context, but it was lots.
