Two people behind a simpler way to track your money.
We're Espen and Daria Larsson, the founders of Billy. We build an expense tracker that helps you see what you're paying for, what's coming up, and where your money goes.
Why we built Billy
Managing subscriptions and expenses can mean keeping track of a lot of small details: a renewal next week, an installment still to pay, or a receipt you need to find again. We wanted a simpler place to put those details.
That is the idea behind Billy. Add your expenses, organize them in a way that makes sense to you, and use the overview to decide what to do next.
You can start free, without connecting a bank account. Local expense tracking works offline. Pro adds optional cloud sync, household sharing, and tools for moving your data in and out.
