Keel
Treasury software for finance teams that has to look as dependable as a bank. The product appears as a real interface with numbers that add up, and not one filler illustration.
- Type
- GeistGeist Mono
- Palette
- Near black, very light grey, emerald green and pale mint.
- Interaction
- A 13-week cash forecast: switch scenarios and drag the controls to redraw the quarter.
Problem
A fintech lives or dies on trust. Generic illustrations or numbers that don’t add up break it instantly.
Direction
Neutrals with a single green, and the product interface built in HTML so every figure is real text.
Key decisions
- Mockups with real domain data: SEPA and Zengin rails, masked accounts, approval rules.
- The forecast is an honest model: the pessimistic scenario really does break the cash buffer.
- On mobile the chart stays pinned above the controls, so you see the effect while you drag.
