They did beat out Myth by 5 months (or 3 months if you go by the official announcement date). It's really impressive that they nailed down Rosuuri and Nacho before Hololive and VShojo made them huge names in the VTuber sphere.
>>21903921You can't compare Holo/Niji/VShojo numbers to the smaller startups. No one outside those three has any brand power, so they're living in complete different universes. Shiki at PRISM has 118k subs but can't crack 100 ccv sometimes. Miori getting 500+ for non-milestone streams is about average considering her sub count. The huge outlier in that regard is Amiya, who barely has 6k subs but regularly has over 100 viewers for normal streams. That's easily the best ratio for any of the startups
