Welcome to Fignis

We are the two people behind Fignis, and we started build­ing it be­cause every se­ri­ous finan­cial de­ci­sion in our lives ended up in a spread­sheet, or in a Python script. One day, we re­al­ized the script was get­ting too com­pli­cated. “I wish there was a tool that helped me op­ti­mize this de­ci­sion vi­su­ally, with­out having to run code every time I want to test some­thing,” we told our­selves. So we de­cided to build that tool. And here we are.

What is Fignis

Fignis is a long-term plan­ning and sim­u­la­tion tool for per­sonal finances. You model your ac­counts and in­vest­ments, your income, ex­penses, and so on. You add future events and de­ci­sions, and it gen­er­ates a pro­jec­tion of your sit­u­a­tion over time. What makes Fignis dif­fer­ent from other cal­cu­la­tors and tools is that it acts as an ab­strac­tion of re­al­ity, giving you a much more pre­cise pre­dic­tion than what you could build with a spread­sheet or an LLM. You can see not only the money you may have, but also the time you have. The time left until you can become finan­cially in­de­pen­dent, retire, reach your goals, and more.

We did not want to build an­other bud­get­ing app, or an app for track­ing every coffee you buy. We did not want to build some­thing that felt like a toy, or a nice-look­ing dash­board that ul­ti­mately said very little. The idea is to re­al­is­ti­cally ab­stract a finan­cial life, with un­ex­pected events, un­cer­tainty, hy­po­thet­i­cal sce­nar­ios, and the abil­ity to play with it. To un­der­stand how things work, and to un­der­stand the impact of your de­ci­sions.

The app has just been born, and we are still build­ing it as two founders with a fairly clear idea that knowl­edge is power. We want Fignis to be a tool that helps you vi­su­al­ize the con­se­quences of your de­ci­sions and mo­ti­vates you to reach your goals.

What this blog will be

We want this blog to be a place to share prod­uct notes, lessons, de­ci­sions, and reflec­tions. It will not be a finan­cial advice blog, nor an eco­nomic news site. It will be a blog about what it is like to build a tool like this, and about what we learn along the way.

Thank you for ar­riv­ing early

If some­thing seems con­fus­ing, useful, or clearly im­prov­able, tell us. At this stage, feed­back changes the prod­uct faster than any roadmap. Re­mem­ber that the app has just been born, and that we are build­ing it with great care. You can reach us on Dis­cord or by email. We read every­thing.

Thanks for read­ing, and wel­come.
