systemprompt.io is a founder-led company that builds self-hosted AI governance software. Its product is a single compiled Rust binary, with PostgreSQL as its only external dependency, that runs inside a customer's own infrastructure. It governs AI clients and agents, including Claude Code, Claude Cowork, and custom agents, across any AI provider. Core capabilities include role-based access control at the tool and data level, scope checks, secret detection and credential isolation so keys stay out of model prompts, synchronous policy enforcement before tool execution, OAuth 2.0 and WebAuthn authentication, and append-only audit logs in PostgreSQL that export to SIEM tools. The product is source-available under the Business Source License 1.1 and can run air-gapped. The company supplies its own services: system installation, hands-on training, and rollout support aimed at making AI governance part of daily work. Its materials map the platform's controls to SOC 2, ISO 27001, HIPAA, the EU AI Act, ISO 42001, and the OWASP Top 10 for Agentic Applications. These mappings are supporting evidence for customer audits, not certifications held by the company.
