Just launched the landing page & waitlist for Prism. It aggregates payment methods onto a single card and then smartly "routes" payments to the card with either the best reward or if they're all the same the cheapest fees following payment rules that the user has set. Any feedback is great and planning to launch late 2025.
The idea is pretty brilliant. I hope it takes off. Good luck.
Thanks for the positive reply, will 100% post here when it launches fully!
