I work with lots of Edtech startups via Emerge.education. I support them with coaching, mentoring, business and brand advice. I can also help build websites and apps, so perhaps we should have a chat.

My advice is not to dive into the tech side of things until the value proposition is right. Sounds like you're well on your way though.

Let me know if you want chat.
