we made an editor that tries to solve document versioning issues

Document versioning is orthogonal to text editors and text editors are a mostly solved problem for most people anyway. Solving people's document versioning issues means meeting them where they are and providing additional capabilities not sending them back to ground zero. To put it another way, if a customer adopts your solution and your company goes out of business, the customer should be no worse off than if they had not adopted your solution.

The minimum viable product is not a text editor because text editors are complicated -- never mind Vim or Word or Emacs, the current state of even Notepad and Nano reflect many years of development.

The great news is that you have people who will talk to you. Ask them what their current versioning problems are. Become an expert in actual document versioning problems before deciding on a solution. Solve one organization's document versioning problems first. Go deep before going broad.

Good luck.
