STELR AI builds enterprise-grade trust infrastructure for Generative AI. We make AI-generated content and AI agent actions cryptographically verifiable, auditable, and non-repudiable, from creation through audit, months or years later. STELR deploys entirely inside a customer's own AWS account: every Bedrock generation is signed with a KMS-backed signature and recorded in an immutable, hash-chained ledger. STELR never sees customer prompts or outputs. Built for regulated industries: financial services, healthcare, government, legal, and insurance.
