Anecdote: I am an independent game developer who views git-annex as unproven, but who would also love to get away from Perforce. However, Perforce is free for up to 20 users, and right now my side project has one other person working on it - $400 for a year of GitLab is a non-starter.

More generally, I am curious how many of the "larger organizations" to which you refer in this context (clients interested in git-annex) are in the games industry, and how seriously interested your company is in trying to cater to that industry's needs? (Lots of game engines enjoy built-in first class support for Perforce due to how established it is in that vertical.)
