What is “Auster”?
Historically, auster comes from the idea of discipline and restraint: choosing what matters when resources are limited. In practice, that means stress-testing assumptions, quantifying tradeoffs, and making decisions you can defend with numbers.
Mission
Give builders, analysts, and students a fast, scenario-first way to model decisions and export outcomes that hold up under scrutiny.
Why scenario-first
Instead of a giant spreadsheet, you run controlled scenarios, compare sensitivities, and see the “why” behind the output.
