Startup Idea: UX Design Approval and Management Platform

Startup idea to develop a software that integrates functionality of both Invision and zeplin.io to create a system where UX designers can share multiple prototypes and clients can visually indicate the approved versions.

I am a ux designer for a startup that has nearly 100 employees. During the ux process, I prototype different designs using Invision.

I send that prototype to the client. Unfortunately, while it is possible to have Invision links sent to clients, there's no way to mark 'approved' for the final version. I would love a solution that is a mix of zeplin.io and Invision where my clients could view all the prototypes and then move the prototype they want into the 'approved' section.

This is impossible now, and so the links get lost in a sea of texts and slack chats.

I solve it now by opening a google doc where I have the 'approved' prototypes with their links. But this is not visual, and people don't check it that often.
