Hi Brendan
I loved the elevator pitch even though I have little knowledge in your field. It is clear what you are working on.
The venture pitch is also detailed and rich with statistics. My only concern is that you are targeting the wrong purchaser. I would recommend that you approach the content authors such as Person, Cambridge…etc. I think if you offer your product with an SDK to allow educational content developer to integrate it within their authoring it will allow you to scale faster and make money.
