I pay for 5 podcasts, I do it via Patreon, Memberful, and a custom (stripe-based) solution. I'm not really sure what problem needs to be solved in this space. I pay for 2 podcasts that I haven't listened to in months, I do it because I pay to support these creators. I don't need/want my listen history to directly correlate to sending money to hosts I like (nor do they, they'd much rather have the constant stream instead of peaks and valleys). Also, I actually hate the idea of "boosts", it just encourages bad behavior (just like IAP's that aren't one-time/DLC/remove-ads).
Patreon bans podcasters sometimes, you also have to be in one of the lucky countries to be able to use it - other people are excluded. There are annoying fees that Patreon (and credit card providers) take on each transaction (afaik around 10%), so the actual podcasters get quite smaller amount compared to what you send...
all those websites take their cut. and visa takes their cut. and still the podcaster can't "cash out" immediately, depending on settlement times and policies of the corporations. Essentially, the middlemen have the creators by the balls, lightning solves that.
