mixxi is a personal-finance product for Australian households. Users upload a bank statement and the platform parses every recurring charge, identifies each provider, and benchmarks every bill against the live market, turning a shoebox of statements into a ranked list of switches worth making.

The challenge

Why it needed to exist

Most Australian households are paying ten to thirty percent too much on energy, mobile, internet and insurance. But proving it requires reading every statement, looking up every provider's current plans, and comparing line-by-line. Comparison sites monetise switching commissions, so the recommendations skew toward what pays best. The actual question (am I overpaying right now, and by how much?) goes mostly unanswered.

The approach

How it works

mixxi parses any PDF, CSV or screenshot from any Australian bank, recognises 1,400+ local providers, and benchmarks each recurring charge against thousands of live plans. The first savings report arrives in under 60 seconds. Every dollar found rolls into a user-defined goal like an emergency fund, a holiday, or a new laptop. Auto-allocation, progress bars and weekly digests turn passive savings into directed momentum. Price-change alerts warn before the next bill arrives, not after.
