About Us

We are a married couple who started to take our financial independence journey more seriously in 2020. It all started with a Google Sheets file to track our net worth and a Python notebook to run Monte Carlo simulations. These tools provided us the confidence to take the leap into early retirement.

We left our well-paid tech jobs after achieving a certain level of financial security that would allow us to take on the fun challenge of creating a startup — without stressing about our finances.

Our goal is to take the key components we used to predict our probability of financial success and transform them into an intuitive, user-friendly tool. No coding skills, complex spreadsheets, or tedious manual work required — just simple, accessible insights for everyone.
