This is great, well done. While at (now defunct) Dotscience we did a lot of work on Dotmesh which you might find interesting: https://github.com/dotmesh-io/dotmesh

I would also look at data science/ML as a potential use for the tool as there are real issues with using Git for training data.

Last point which is more of a tip: Show don’t tell. If you did some side by side workflow walkthroughs showing the difficulties with other tools it will make it easier for people to see that this problem is real (which it definitely is)
