Quantitative Risk Analysis, Made Practical
Build, understand and apply quantitative risk models — from project schedule & cost Monte Carlo to AI-built Excel simulations, a ready-made model library, expert-led courses and an Ask-the-Expert network.
Everything you need for QRA
One platform to model, learn and consult.
Project schedule & cost Monte Carlo
Build or import an MS-Project plan, add a risk register, and simulate finish-date and cost distributions with a native CPM + Monte Carlo engine — with AI-suggested distributions, analysis and PDF reports.
Explore →AI · Build an Excel Monte Carlo model
Describe a problem; the AI asks the right questions, builds a probabilistic Excel model with iz* distributions, and hands you a workbook ready to simulate in iziRisk Quantum.
Explore →“Just iziRisk it!”
Upload a deterministic Excel model; the AI finds the key output, ranks its drivers with a tornado, and recommends distributions to turn it probabilistic.
