Introducing the era of Provable AI
Sigra is a secure AI analysis platform for adversarial and regulated environments. It allows organizations to apply AI to sensitive data while preserving custody, recording reasoning, and producing results that can be independently verified under scrutiny.
Local processing under physical custody. Privileged material never leaves your infrastructure.
Verify conclusions without exposing privileged content. Analytical proof separates from document content.
Every conclusion links to verified source material. Complete chain of custody from input to output.
Identifies missing documents and unexplained gaps in the evidentiary record.
Analysis can be independently verified by opposing experts, neutral parties, or the court.
Verification is not adopted by choice. It is enforced by opposing counsel, by judges, by evidentiary rules. At the moment of challenge, unverifiable AI analysis is exposed — and often cannot survive the objection.
Sigra Legal is the first vertical, not the platform itself. Discovery analysis, gap detection, privilege review, expert witness support — built on cryptographically verified infrastructure.
Other regulated domains face identical verification requirements. Medical diagnostics challenged in malpractice proceedings. Financial models scrutinized by regulators. Engineering analysis tested under cross-examination. The architecture remains constant. The applications vary.
This is infrastructure for AI that will be challenged. Litigation establishes the requirement. Every other domain operates under the same constraint once scrutiny begins.
Sigra is shaped by decades of adversarial litigation, failure analysis, and cryptographic research — domains where claims must survive independent review. The system is not built for demonstration. It is built for deposition.
"After decades of manually searching through millions of documents to find smoking guns hidden by sophisticated defendants, I recognized that AI could transform this work—but only if it could be trusted.
The problem wasn't capability. It was verification.
Sigra was built to solve that problem."
Sigra does not use a sales team.
Technical walkthroughs are conducted directly by the Founder.
Questions about architecture, verification methodology, or deployment are addressed without intermediaries.
Most legal AI systems focus on generating answers. Sigra is designed to preserve proof. It records what data was examined, how conclusions were formed, and what was not present in the record.
In adversarial settings, results are challenged. Systems that cannot show their work rely on trust. Sigra is built so its analytical steps can be independently reviewed without exposing sensitive data.
No. Sigra is designed to support professionals working under scrutiny by making analytical processes inspectable and reproducible. The system surfaces evidence and flags gaps. The judgment remains yours.
