(02) — House

A calmer wayto handle money.

Zestrel began with the question from our film: where did the money go? We built the ledger we wished we had, one that answers it in real time.

(01)Who we are

Small house,steady hands.

Designers, engineers and former private-bank staff who care more about calm than charts. Every feature must pass one test: does it make the month feel lighter?

We keep the app spare on purpose. Fewer screens, truer numbers and savings that happen without a second thought.

(02)Principles

I.Privacy

Private by default.

Read-only connections, encrypted data and no selling of your information. Ever.

II.Clarity

Clear over clever.

One number you trust beats a dashboard you never open.

III.Real life

Built for real life.

Shared rent, uneven paychecks and surprise bills are the normal case, not the edge case.

(03)Milestones

How we got here.

I.
A spreadsheet, a whiteboard and the first “left to spend” number.
II.
Live categories and the first savings ring.
III.
Auto-save launches, with safe-to-save checks.
IV.
Family budgets, bill reminders and our first film, made with Advaire.
