Jack Conte has been doing patreon full-time for years now, it’s unlikely he’ll have more work than when he was actually trying to get the thing off the ground.

The current pomplamoose setup is probably not going to change. You can find old vlogs where they explain the setup they were intending, and Jack posted a video somewhat recently where he explains the thing, but basically they arrange and record a month worth of songs in a day.

Well, as I understand it, Pomplamoose is mostly run by Nataly, not Jack (who's the CEO of Patreon).

Seems to be wider than that e.g. I know Ben Rose & others have handled production of many of the songs, arrangement is done live in the studio.
