Yeah, Jerome worked for Manga for quite a while, but Manga went down the crapper (I seem to recall Jerome had a social media meltdown at one point too) and they parted ways. Jerome started Animatsu, and made enough of a success of it, that when Manga hit the skids, he was able to buy it and bring it back to life, working pretty much in lockstep with Funimation.
The rest is misery/history.
