I'm the founder of Simul Documents (https://www.simuldocs.com) and about 8 months ago we posted our MVP to hacker news:

Bringing the features of Git and GitHub to Microsoft Word (https://www.simuldocs.com/blog/ben-morris/version-control-fo...)

We have since had 1300 BETA users upload over 7500 documents that have helped us to rebuild our product from the ground up. I wanted to say a big thank you to all the early adopters in this great community and we are excited to announce that we have left our BETA phase.

Your feedback has been invaluable, it has not only greatly improved our document comparison algorithms but directly led to the development of many new features including:

Document Copies / Pull Requests (https://www.simuldocs.com/blog/ben-morris/document-copies)

Task Tracking (https://www.simuldocs.com/blog/ben-morris/task-tracking)

Our focus is now on ensuring a stable and scalable platform and developing an enterprise edition allowing organisations to host Simul on their existing IT infrastructure.

Thank you again for helping us improve our product.
