Verisum is a web and API service for organizations governing AI decisions and documenting accountability with cryptographic proof. Its tools are grouped into Govern, Monitor, and Prove. Govern covers organization surveys, AI system and vendor registers, policy generation, shadow-AI tracking, model registries, regulatory feeds, and compliance frameworks. Monitor provides drift monitoring, incident logs, escalation workflows, runtime signals, staff declarations, and team management. Prove includes decision ledgers, approvals, attestations, incident locks, provenance graphs, public verification, Trust Exchange, and on-chain anchoring. Plans include Explorer, free forever; Core at £129 per month; Assure at £499 per month; and Verify with custom pricing. Core is positioned for startups and scale-ups using AI, while Assure and Verify address regulated, multi-system, or high-stakes deployments. Verify can anchor attestations, incident locks, and provenance records to EVM-compatible blockchains including Ethereum, Polygon, and Arbitrum. The HAPP Protocol offers REST APIs for approvals, attestations, provenance, exchanges, incident locks, and public verification. Verisum says data is encrypted in transit with TLS 1.2 or above and at rest with AES-256. Its DPA says customers must not submit UK GDPR special category data.
