Maybe "cloud native" will have a pull for game companies, but I am not so sure. I think a lot of studios would want to self-host.
"Git compatible" is an interesting phrase; does Diversion use the same type of backing store? If so, I am not so sure it will handle large files as well as hoped.
I had to solve this problem myself, and I did, but it required a different storage design.
Can it handle binary files? Is there a plan for doing so beyond "commit the entire file every time" or "use xdelta"?
I think this is how fourth gen version control systems will be defined. Game studios have a lot of binary assets, so this will be important.
All in all, I could see a product like this succeeding, but I think taking VC money was a mistake because there may not be enough space in the market for a company that has to keep growing to satisfy investors. I am taking zero VC, and that will allow me to make money on as few as three clients.
Anyway, I wish you both the best of luck!
