thanks for the question! for creators who are on either platform already, nothing will be changing at this point.
Jack, Patreon founder and CEO, explained in this interview a bit about the additional services part of your question:
there’s a whole segment of the market that doesn’t want to build a membership business on someone else’s platform, they want full control of the branding, they want full control of the experience. Right now Patreon is unable to serve that market, if we were to build that, it would be a completely separate thing. Working with the Memberful team accelerates us into that market segment, so it gives us a very big head start. I would say mostly that’s where the value is.
there’s a market segment that we are unable to serve right now, and Patreon’s mission is to fund the creative class. That’s not a small thing: we want to serve all creators, all creative people who are putting things either online or even in person, and this is a way to accelerate our progress to our mission.
Hope that helps! I’d take a look at some of the creators on Memberful to see how they’re using it versus creators on Patreon.
