The story

It started as a spreadsheet.

I’m Guillaume, an engineer and the person behind Finzya.

I managed my finances with spreadsheets for years, and they worked pretty well. I could track what I wanted, organise things my way and build the analysis I needed.

Over time, I wanted to do more: manage more accounts, improve the charts, import transactions, build projections and look further ahead. The spreadsheet grew with it, and eventually maintaining the whole thing became a job in itself.

That’s where Finzya started. I wanted to keep the flexibility and control I had with a spreadsheet, while making the whole thing easier to manage and capable of doing much more.

Why Finzya

Why build another finance app?

I tried other personal finance apps, but never really found one that worked the way I wanted.

I didn’t just want to know how much I’d spent this month. I wanted to understand how my finances had changed over time, how my savings and investments were developing, and where I might be heading in the years ahead.

I also didn’t want everything to happen automatically in the background. Some automation is useful, but I still want to know what’s happening with my money and have control over what goes into the app.

Finzya grew around those two ideas: look further ahead, without giving up control.

How it’s built

The principles behind it.

Stay in control

Finzya should make managing your finances easier without hiding how everything works or deciding what matters for you.

Useful over feature-heavy

Features should earn their place by making something easier to manage, understand or plan — not just by making the app look more capable.

Look beyond this month

Budgets and spending matter, but so do the years ahead. Finzya is built to connect what is happening now with longer-term savings, investments and plans.

Simple where possible

Financial planning can become complicated quickly. Finzya should keep the interface calm and understandable without removing the detail that matters.

Designed for the detail

Built with a bigger screen in mind.

Finzya is desktop-first by choice.

There can be a lot to look at when you’re managing your finances: years of transactions, several accounts, budgets, charts and projections. Some things are simply easier to understand when you have the space to see them properly.

That doesn’t mean ignoring mobile. A phone is useful for checking something quickly or making a small change. I just don’t think the whole desktop experience needs to be squeezed onto a smaller screen.

Behind the scenes

A one-person project.

Finzya is designed, built and maintained by one person.

I’m building Finzya as something I want to keep using for years. What I need from it will change over time, and I expect the app to change with it.

The app will keep developing based on what I find useful myself, as well as ideas and feedback from the people using it. There will always be more that could be added; the challenge is making Finzya more useful without losing the simplicity and control that made me want to build it in the first place.
