Building Business Confidence in Artificial Intelligence with AI TrustMark

AI TrustMark describes itself as the independent evidence layer for AI services. It checks suppliers, products and customer evidence, then publishes what was examined, how deeply it was checked and when. AI TrustMark is operated by AI Build Group Ltd, and it discloses that relationship. Visitors to The Business Show London 2026, ExCeL London, on 11–12 November 2026, can learn more about AI TrustMark (https://www.ai-trustmark.org) at Stand B501.

Why does business AI trust matter?

AI tools are being adopted faster than many organisations can assess them. Buyers are often asked to rely on sales claims about security, privacy, accuracy and governance, with little evidence. Responsible AI adoption means asking practical questions: who is accountable for the tool, how decisions are explained, what data it uses, where human oversight sits, and how risks are monitored over time. Good AI governance and AI risk management, guided by published frameworks such as the NIST AI Risk Management Framework, help organisations adopt AI with confidence.

What is AI assurance?

AI assurance covers the techniques used to check that AI systems are developed and deployed safely and responsibly. The UK government's Introduction to AI assurance (https://www.gov.uk/government/publications/introduction-to-ai-assurance) explains the key concepts. AI TrustMark only describes something as verified when evidence supports that specific claim. Each public record identifies the scope checked, the depth of verification, any unresolved gaps and when it was last assessed.

What does AI TrustMark offer?

• A free directory listing for any AI service, so suppliers can list or claim their product.
• Published reviews from customers, with an explicit verification level. Suppliers cannot pay to remove a negative review or edit customer text.
• Assurance at Bronze, Silver or Gold, describing investigation depth: Bronze uses external evidence, Silver adds operational evidence and Gold adds technical examination where access is granted.
• A separate Assurance Score from 0 to 100 for the named scope, plus a Low, Elevated or High Impact classification that sets which controls and evidence strength apply.
• Evidence built for buyers to reuse in procurement, so a supplier's evidence can be checked once and reused across tenders.

Bronze, Silver and Gold are not a league table, and deeper investigation is not a claim that one supplier is better than another.

Frequently asked questions

Can suppliers pay for a better result? No. Payment can fund review collection, verification work or assessment depth, but it cannot buy review stars, directory position, a higher Assurance Score or a predetermined outcome. Assessments of related organisations, including AI Build, are disclosed and run on the same commercial terms.

Is AI TrustMark a certification or regulatory scheme? No. It is not a government scheme, not a UKAS-accredited certification body and not a substitute for ISO/IEC 42001 certification or a buyer's own legal obligations. Its assurance levels and scores are evidence to inform procurement and risk decisions.

Who is AI TrustMark for? Buyers, including public-sector procurement teams, who need evidence before choosing an AI supplier, and suppliers who want to prove what they say and reuse checked evidence in tenders.
