Money & Payments
How instant payment systems and AI agents actually work: Pix in Brazil, and how Nim finds savings and guides your decisions.
This cluster covers two different kinds of infrastructure that both do the same thing: remove friction from moving and managing money. Pix is Brazil’s instant payment rail, processing 63.8 billion transactions in 2024 across 170+ million users, and it is the clearest real-world example of what an instant, universal payment system looks like at national scale. Pix for gringos covers the practical side for foreigners.
Nim is Liminal’s version of that same idea applied to financial decisions rather than payments: it can save on your behalf and find the idle cash and forgotten subscriptions you would otherwise miss. Both Pix and Nim solve the same underlying problem: manual, friction-heavy money management does not scale to how people actually live and spend.
