"Functionality"...you're making the same mistake almost every platform before you made. Your UI/UX designer has less than 3yrs experience at his post but most of these systems require 6yrs of experience or more.

Design wise, your branding and site has problems to the extent of seeming rushed and like a fly by night scam. I think I saw your post on Medium. Your team really needs to work on your branding and with a UX designer with less than 3yrs experience and no body of work to validate your claim, I simply cannot invest or recommend anyone invest in your company until your past UX work has been validated.
