HBV angle: a LatAm version with Pix/boleto categories and a mascot-led, privacy-first positioning, entered through ASO and SEO. Saturated category; weakest of today's existing entries.

Jobs to be done

When my spending is spread across Pix and several cards, I want a private tracker that logs entries from receipts, so I can know where my money goes without sharing bank logins.

HXC

Marcos · 31 · São Paulo: Uses Pix for everything, loses track of spending across cards. Frustration & buying signal: Wants a private, simple tracker that reads Pix receipts; would pay a small yearly fee.
