Pricing

Priced on confidence, not on call volume alone

Overage billed at $0.40 per 1,000 calls. Two months free on annual prepay. Grid requests weight as ten point-calls.

Questions people actually ask

What happens when I go over my plan?: You are billed for the overage at $0.40 per 1,000 calls. We do not hard-stop a paying customer mid-incident — the moment you most need the forecast is the worst possible moment to cut you off.
Why does a grid call cost more?: A grid request weights as ten point-calls. A single bounding box can return a million grid points, and pricing it as one unit would be incoherent.
Is ensemble spread really on the free tier?: Yes. The spread is the product, not an upsell. What the paid tiers add is longer horizons, per-member access, more variables and an SLA.
Do you offer free access to anyone?: Verified emergency management agencies and academic researchers use the platform free. Contact us with your institution and use case.
Can I self-host?: Enterprise customers can deploy into their own VPC or on-premise. That is the tier where custom grids and variables also become available.
