Jujutsu is not "VC funded". But some of the developers, including me, work at East River Source Control (I worked on Jujutsu before that, too). The majority of the code in the project doesn't come from us -- or Google, for that matter. We don't allow people to approve patches when the author is from the same company, anyway.
(also at ERSC here, hi Austin!) Heck, I have not had enough bandwidth to do as much upstream work as I initially thought I would when I started there!
