Summary
Verisum is a web and API platform for organisations governing AI decisions and documenting accountability with cryptographic proof. Its tools are grouped into Govern, Monitor, and Prove. Govern includes organisation surveys, AI system and vendor registers, policy generation, shadow-AI tracking, model registries, regulatory feeds, and compliance frameworks. Monitor covers drift monitoring, incident logs, escalation workflows, runtime signals, staff declarations, and team management. Prove includes decision ledgers, incident locks, attestations, approvals, Trust Exchange, provenance graphs, public verification, and on-chain anchoring. Plans include Explorer, free forever; Core at £129/month or £1,238/year; Assure at £499/month or £4,790/year; and Verify with custom pricing. Core is positioned for startups and scale-ups using AI, while Assure and Verify target regulated, multi-system, or high-stakes settings. Verify can anchor attestations, incident locks, and provenance records to EVM-compatible blockchains including Ethereum, Polygon, and Arbitrum. The HAPP Protocol provides REST APIs for approvals, attestations, provenance, exchanges, incident locks, and public verification. Verisum's DPA says the service is not designed for UK GDPR special category data, which customers must not submit.
