Personal finance for people whose income is irregular, whose costs are rent and whose main assets are potential and student debt. It skips the advice written for mortgages and pensions and deals with what is actually in front of them.
What a v1 does5 features
- Budgeting that survives irregular and multiple incomes
- Student debt handled as a first-class part of the plan
- Rent, deposits and moving costs planned for properly
- Emergency fund built at a pace this income can sustain
- Plain explanations of the things nobody teaches
The market
Monarch has roughly 1.8M monthly users and YNAB about 1.4M, at $99.99 and $109 a year. Mint's closure left the largest gap in consumer finance and three paid products grew into it. This is costed at $7 a month.

Why this audience
A large part of this audience is early in earning, with irregular income, rent rather than a mortgage, and advice written for somebody twenty years older. The content speaks to that stage specifically. Money software built for it is rarer than it sounds.

Fifty thousand paying users is the ceiling every one of these pages is drawn against, not a forecast. It opens at a thousand, the bottom of the range, so the first figures you see are the modest ones. What the cap buys is comparability: the same range on every app, and the percentage of the audience it takes as the number that moves.
