When vtubers were barely a thing Cover (Holo parent company) took all their revenue sources and reinvested them back into the girls. While other corpos took the money and ran, Cover made sure that the vtubers under them were happy enough to remain via outlandish things such as regular payment and giving them the largest cut of their own superchats and membership fees and merch. It built a strong foundation with talents wanting to actually remain resulting in a pool of performers that reached many people. This created a feedback loop resulting in more money coming in, being reinvested, and talents trying harder inevitably causing more and more vtubers to try and join Hololive and inevitably causing only the best of the vtubing world to join. Last year some of these girls held over 12 in-person concerts.
It's why brands like them too because they're not a risk unlike some other corpos, one of which being so retarded that they quite literally exploded and died completely last night.
