The problem
Two ex-bank operators had a thesis about cash-flow forecasting for agencies, a Figma file, and an investor meeting nine weeks out. Two dev shops had quoted them five months and six figures. They needed something real in front of users before the meeting, not after it.
What we built
A cash-flow forecasting platform that syncs bank transactions, categorizes them, and projects runway 13 weeks forward. Multi-entity support from day one — their target customers all run three or four legal entities, and every existing tool forced them into spreadsheets to consolidate.
We scoped hard. The forecasting engine, bank sync, and one clean dashboard shipped in v1. Client portals, invoicing, and the reporting suite were mapped and deliberately deferred to v2 so the core loop could get in front of real users first.
Categorization was the piece that decided whether the product felt magic or tedious. Rather than ask users to tag six months of history, we match recurring transactions against their own past behavior and surface only the genuinely ambiguous ones — typically a dozen out of several hundred.
Results
- Live with paying users in 4 weeks
- 137 signups in the first month with no paid acquisition
- Raised a $1.4M pre-seed off the working product
- Cut client cash reporting from roughly 6 hours a month to 20 minutes
