The person behind Fontana
Built by an engineer.
Shaped by real work.
The best part of an engineering job shouldn’t disappear into a project folder.
Fontana began with a familiar frustration: useful answers buried in PDFs, and useful calculations scattered across spreadsheets. Finding and rebuilding the same work takes time away from the engineering itself.
It brings that knowledge together: answers you can trace to a source, calculations you can inspect, and tools your team can use again.

Your firm's knowledge should stay useful.
A calculation built for one job can become a tool for the next engineer and the next project.
