Anyone created a micro mobile-game studio?

I'm thinking about partnering with a graphic designer, and build ""small" mobile games (hypercasual/casual). Then I will try to find publishers for those games and we do revenue shares.

Anyone doing it over here? Can it be economically viable? From what I heard mid-successful games can already rake in $100k-$300k per month, which would make it an interesting business.

Anyone has experience on this?
