Independent software for the analytical mind.

Jonsson Associates is a small, independent firm that publishes a family of focused web products. Where general-purpose software often fails the specialists, we build the second-order tools — the ones you reach for when the spreadsheet isn't enough.

Today we ship four properties: a three-statement Financial Forecaster, a multi-user PERT scheduler, a GEDCOM-based FamViz tree visualizer, and a forthcoming set of Exercise Widgets.

Our products share a utility-first philosophy: zero bloat, high keyboard accessibility, robust data portability, and quiet interfaces that get out of your way.
