Marcus, the Digital Banking Product Manager at Monzo, has a problem that's keeping him up at night. Their customers are constantly calling support asking, "What was that $47.23 charge from 'SQ *COFFEE CORNER NYC' anyway?" or "Why do I have so many 'Miscellaneous' transactions in my spending report?"

The raw transaction data from payment processors looks like hieroglyphics: "AMZN MKTP US*TO4A23EF5", "SQ *DOWNTOWN YOGA", "PAYPAL *SPOTIFY". Customers see these cryptic descriptions in their banking app and get frustrated because they can't track their spending patterns or understand where their money actually goes.

Marcus knows that if they could automatically transform these mysterious merchant codes into friendly categories like "Shopping", "Food & Dining", or "Entertainment", customers would love their banking app and call support 60% less often. The technology exists - they just need someone to build it.
