Hololive shows the benefits of being part of a well run agency, with the most popular talents often having partnerships with popular brands or the ability to pursue their passions. A few of the music oriented talents are signed with labels, the sonic fan had many collaborations with Sega etc.

It's not uncommon to see their appearance in convenience stores since they've got so many campaigns with various brands kinda like any celebrity.
That promotion does seem to pay off though, one thing with Hololive is apparently the talents have to pay for the production of their own stuff such as music videos and merchandise. But as a result they get a far larger cut than the 2% figure thrown out for Nijisanji.

That said even Hololive will have its fair share of drama, like what happened with Rushia.
