Eugenius builds desktop-first apps across finance, construction, support and learning — accurate, private, and yours to keep. Three decades of real-world experience, working alongside AI.
Eugenius is a studio with a single obsession: software that earns your trust by being correct, staying private, and never holding your work hostage. Each app is desktop-first and runs on your own machine, so the people who depend on it own it outright.
The studio is led by founder Eugene Maestas, who brings three decades of real-world experience to the way every product is designed and built. That experience now goes into the software itself — paired with AI to move faster without ever cutting corners on accuracy.
The result is a growing suite of apps for different industries, all held to the same standard: runs locally, provably accurate, no lock-in, signed and secure.
Four principles hold every app to the same bar — no matter the industry it serves.
Your data never leaves your device. The software runs where you work, not on someone else’s server.
Built-in checks, not guesswork. Every figure is verified by the software itself before you ever see it.
Own it — no monthly hostage fees. Your work and your data stay yours, with no subscription holding them.
Code-signed installers on every release, so you always know exactly what you are running and where it came from.
Different industries, one standard — accuracy, privacy, and software you own.
Bookkeeping, taxes and net worth that stay accurate automatically — your books on your machine.
