FIGNIS· Personal finance simulator
Simulate your finances, retirement and financial decisions with clarity
What is FIGNIS?
FIGNIS is a personal finance simulator.
Most personal finance tools are built to track the past: what you spent, where your money went, and how your accounts changed. FIGNIS is built for a different question: what could your financial future look like?
FIGNIS helps you create long-term financial projections using your net worth, income, expenses, assumptions and life scenarios. Instead of maintaining a spreadsheet, you can model decisions like changing jobs, buying a home, increasing savings, reducing income, retiring earlier, taking a career break or testing more conservative market assumptions.
It is NOT a budget tracker, because the goal is not to categorize every transaction. It is NOT an AI chatbot wrapper. FIGNIS gives you a structured, deterministic projection engine where assumptions are visible, scenarios are comparable and the numbers can be adjusted directly.
It is designed for people who already think in hypothetical scenarios: FIRE planners, long-term investors, founders, freelancers, couples making financial decisions, or anyone trying to understand whether their current path is sustainable.

Back in 2024 I was almost ready to quit my job I was ready to jump into another company I already signed everything... they said 'Hey Dom I'm sorry but we had a financial problem and we are not able to hire you.' In this case the event of course was a negative event But I changed my perspective and said myself okay maybe this is the right time the right opportunity to jump into something different that was subject
Reframe A Rescinded Job Offer As Permission To Go All-In On Your Side Project
Dom's new employer pulled his signed offer at the last minute, leaving him jobless on paper. Instead of scrambling for another role, he reframed the rejection as the forced push he needed and went full-time on Subgen — which became his 7-figure exit. When the safety net snaps, treat it as permission, not punishment.
My goal was to just get my 10K, move to Bali, live the indie hacker lifestyle. I just realized — why not shoot for the stars, right? Why not build the first 100 million ARR bootstrapped company.
Aim for $100M bootstrapped — not the $10K Bali indie-hacker ceiling
The $10K MRR indie hacker ceiling is a self-imposed mental cap. Aim higher from day one — being too reserved about a working product costs more than being too aggressive.
There's a play for whatever you're stuck on.
