The address-level risk platform

282.9M U.S. addresses, graded for risk.

Three data products, one platform. Atlas United grades every U.S. address across 54 perils. AtlasCast forecasts 10 storm perils to each one, refreshed four times a day. TrueFixR storm data shows where damage has already hit. The risk a property carries, the storm coming for it, and what it left behind.

How it works

Address in. Audit-ready score out.

Our deterministic peril model spans 282.9 million addresses across 54 perils, calibrated against two decades of observed severe events and a sixteen-day forward layer. Every score is timestamped, versioned, and accompanied by a reason code — patent claim 30, USPTO 64/070,786 — built to survive regulatory examination.

AtlasCast · Live forecasting

Atlas United grades the risk. AtlasCast forecasts the storm.

Static grades tell you what a property is. AtlasCast tells you what's coming — a live, per-address severe-weather forecast built on federal weather models, refreshed around the clock.

  • 10 storm perilsTornado, hail, wind, flash flood, heavy rain, winter, ice, wildfire, hurricane and coastal surge — each with its own trained model.
  • Per addressScored against 282.9M U.S. address points, with modeled likelihood, severity and a reason on every lead — plus county grades and property value in the path.
  • 24h to 16dForecast windows from tomorrow to two weeks out, refreshed four times a day.
  • Federal dataBuilt entirely on first-party U.S. government weather models. No third-party feeds.

Data products

Three data sets. One platform.

Grades tell you what a property is. AtlasCast tells you what's coming. TrueFixR storm data tells you what already hit. Use one, or all three through the same API.

01 · What a property is

Atlas peril grades

A deterministic A–F grade and 0–100 percentile for every address across 54 perils, with the model version and methodology trace on every response.

  • 54 perils, one schema
  • Flood, wind, fire, seismic, chronic climate
  • Rate-filing-ready provenance
Property risk API
02 · What’s coming

AtlasCast storm forecast

Trained machine-learning forecasts for 10 storm perils, scored against 282.9M U.S. address points and refreshed four times a day from NOAA weather models.

  • Tornado, hail, wind, flash flood, heavy rain, winter, ice, wildfire, hurricane, coastal surge
  • Modeled likelihood, severity and reason per address
  • County grades, plus property value and people in the path
  • 24-hour to 16-day forecast windows

03 · What already hit

TrueFixR storm data

Address-level storm-damage leads and event history, built for roofers, restoration crews, adjusters and emergency management offices that want the data itself.

  • Damage leads by county or state, up to 365 days back
  • Radar-reported hail history back to Nov 2019 (bulk)
  • Peril breakdowns and flood-risk context
  • 13-endpoint JSON API, one bearer token

Methodology

Eight model layers. One unified grade.

Atlas United is a purpose-built deterministic peril model. Each layer is independently calibrated against decades of observed events and folded into a single audit-ready grade per address — no black-box blending, no proprietary aggregator math.

Why teams move off legacy vendors.

Legacy stacks were built when peril modeling meant licensing one vendor's black box and trusting the output. Atlas United is a transparent deterministic model with per-field methodology trace — designed for the way underwriters and regulators actually work.
