On your hardware. In your facility. Under your control.
A fixed annual contract with no variable costs, no usage meters, and no surprises after lock-in. A direct relationship with the people who built it. This offer closes when the founding circle is complete.
Structurally impossible to hallucinate — not filtered
Fixed annual contract. No variable costs. No usage surprises. This relationship will not be offered again once the circle is complete.
Lease and purchase options. Your hardware, your facility. Upgrades and patching available separately.
The full reasoning system runs in your environment. No cloud dependency. No data leaves your perimeter.
Causal models built for your domain, your data, your specific reasoning requirements.
Systems design, configuration, and installation included. Capacity grows with your business under the fixed contract.
Direct relationship with the team. Not a ticket queue. The people who built it.
Access before public release. Influence over what gets built next.
The highest-capacity causal model we build. A dedicated resource at a scale that only makes sense at enterprise.

Every source is publicly available, institutionally maintained, and traceable to its origin. The knowledge graph can be independently audited.
No configuration. No prompt engineering. You bring the data. We build the reasoning.
Send your data via API — any format. The system automatically extracts entities, relationships, and causal structure. Your knowledge graph is built and compressed. Ready in minutes.
Ask questions as you would ask a domain expert. The system traverses the causal graph, finds the relevant paths, and constructs an answer from verified relationships.
Every response includes the answer, the causal chain that produced it, and a proof identifier. If the answer cannot be derived from your data, the system says so.
Counterfactual queries let you ask what the outcome would be if a variable changed. Exact answers from causal structure, not statistical estimates.
Each response includes the causal trace that produced it — auditable, reproducible, legally defensible. Every claim traceable to its source.
Each customer's graph is mathematically isolated. Not by policy. By the structure of the system. One customer cannot access another's data.
GDPR Article 25, HIPAA Safe Harbor, SOC 2. Not by configuration — by the architecture. Privacy by construction, not by checklist.
The guarantees are theorems. They do not degrade with scale or edge cases.
Formally verified in Lean 4. Not learned — derived. The mathematical basis for zero hallucination.
A proof completed May 2026 establishes that every inference terminates at a verifiable record. Not a timeout. A theorem.
Inference does not require a multi-billion parameter forward pass. Graph traversal. Fraction of the compute cost at a fraction of the latency.
Lossless. The geometry that was always in your data, read out. 1TB of knowledge fits in 12GB.
Every tier includes full access to the Hailstone platform. We don't gate features — we scale services.
Every tier includes full platform access — no features gated by tier.
The difference is the scale and nature of services, not what you can do.
We are seeking non-profit, community-focused, and academic institutions for trial and evaluation partnerships — with particular focus on drug discovery.
Causal reasoning over biological knowledge graphs can identify novel compound pathways and treatment mechanisms for diseases where commercial incentives are insufficient. If your institution works in this space, we want to hear from you.
Express interestThe system is running. The API is ready. Founders Circle contracts are available now for a limited number of founding enterprise partners.
