Istari · Strategy and Insights Modelling

Public-sector decisions,
made with the data.

We’re a studio that turns the data the public sector already collects — administrative records, operational feeds, regulatory filings — into forecasts, models and dashboards for ministries, agencies and regulators in Canada and Germany. Clean energy, public safety, defence, transport, taxation. Decision-ready intelligence in plain language.

How we work

Three steps. No surprises.

A simple process for all teams. Keep scrolling — work follows.

01
Scope
Two-week sprint to map what's measurable from administrative and SCADA data, and where uncertainty actually lives.
02
Model
Hierarchical Bayesian models in PyMC / Stan. Code reviewed. Method notes in plain language — readable on a phone.
03
Ship
Dashboards, briefings and CSV feeds that get used on Monday mornings. We stay around to maintain them.
