To build trust for an AI company, list every public claim, attach the strongest available evidence, rewrite or remove anything unprovable, publish training use, retention and model providers plainly, and review the claims whenever a model, provider or certificate changes.
AI buyers trust what they can check, not what you claim. Every unsupported adjective on your website becomes a question in someone's security review.
A new restaurant earns trust with an open kitchen and a dated hygiene certificate, not a bigger sign. Many AI companies do the opposite and add louder claims when buyers simply want to see the kitchen. This guide shows how to audit every public AI claim, attach the strongest evidence available, rewrite what you cannot support and keep the proof current as models change.
Buyers now discount AI claims by default
Enterprise buyers have learned to ignore AI adjectives. Almost every product calls itself intelligent, secure and responsible, so those words carry no information. Regulators have also begun to treat unsupported AI claims as a legal matter rather than a marketing one.
In March 2024 the US Securities and Exchange Commission settled charges against two investment advisers over misleading statements about their use of AI. In September 2024 the US Federal Trade Commission announced Operation AI Comply, stating that "there is no AI exemption from the laws on the books". Its rule banning fake reviews and testimonials has applied since 21 October 2024.
Inside most AI companies the cause is simple. Marketing writes the claims, engineering and security hold the evidence, and nobody checks one against the other. A buyer's security reviewer then turns each unsupported phrase into a follow-up question, and each question adds days to the deal.
The evidence ladder: what each claim is worth
Buyers weigh evidence by who produced it and whether they can check it. We recommend ranking evidence on five rungs, with every important claim on rung three or higher.
| Rung | Example | How buyers treat it |
|---|---|---|
| 1. Asserted | "Enterprise-grade security" | Ignored, or turned into a question |
| 2. Documented | A dated AI use or retention policy | Useful if specific and current |
| 3. Tested | Evaluation results on a described test set | Credible if the method is visible |
| 4. Independently verified | SOC 2 Type II report; ISO/IEC 27001 or 42001 certificate | Strong, if scope and dates match |
| 5. Customer-confirmed | A permitted reference or case study | Strongest for business outcome claims |
Two rules make the ladder work. First, match the rung to the claim: security claims need rung four, and business outcome claims need rung five. Second, never borrow a rung. A SOC 2 Type II report, an auditor's test of controls over a period, verifies only what its scope names.
Four steps to turn claims into evidence
- Build a claims ledger: copy every public claim from the website, trust page, pitch deck, sales emails and documentation into one sheet, including implied claims such as logo walls.
- Attach evidence and a rung: record the evidence, its rung, its date and an owner. A claim with no evidence sits on rung one, however true it feels.
- Rewrite, prove or remove: turn each rung one claim into a checkable statement, schedule the work to prove it, or delete it.
- Publish the facts buyers ask for first: state training use, retention, model providers, human oversight, security testing and a dated change log.
For security testing, refer to the OWASP Top 10 for LLM Applications 2025. It names risks such as prompt injection, where hidden text manipulates a model. Publish an AI use policy as well. IBM's 2025 research found that 63% of organisations lacked an AI governance policy, so a clear one stands out.
A worked example: auditing five claims
Hypothetical example. A 40-person AI company selling contract-review software audits its homepage and trust page before a round of enterprise deals.
| Original claim | Rung found | Action taken |
|---|---|---|
| "Bank-grade security" | 1: no evidence named | Replaced with SOC 2 Type II scope and period |
| "Never used for training" | 2: provider terms unchecked | Confirmed in writing; provider listed as sub-processor |
| "99% accurate" | 1: no test set | Replaced with dated results and known weak spots |
| "Trusted by leading banks" | 1: one ended pilot | Removed until a customer agrees to be named |
| "Responsible AI by design" | 1: no detail | Replaced with AI policy and change log link |
The result is a page with fewer claims and more checkable facts. The most dangerous claim was not the boldest. It was the training-use statement, because it was specific, believed by buyers and not fully verified.
A quarterly credibility review
In practice, credibility decays quietly as models, providers and customers change. We recommend a short quarterly review with the founders, product lead and security owner. Treat every gap as an action with an owner and a date.
- Ledger current: every public claim is listed with its evidence, rung, date and owner.
- Key pages clean: the homepage, trust page and pricing page carry no rung one claims.
- Scope stated: each report or certificate names the product and period it covers.
- Customer proof permitted: every logo, quote and case study has current written permission.
- Change triggers set: any model, provider or certificate change prompts a ledger review.
The urgency is rising. EU AI Act transparency obligations under Article 50 have applied since 2 August 2026. ISO/IEC 42001, published in December 2023, has made AI management certifiable. Specific, consistent and checkable claims will increasingly prevail.
The bottom line
Conclusion
The restaurant with the open kitchen needs no bigger sign, because diners can see the work. AI companies earn credibility the same way: through claims that rest on evidence a stranger can check, matched to the right rung and kept current.
The method is plain: list every claim, attach evidence, rewrite or remove what you cannot prove, and review whenever something changes. This week, copy every claim on your homepage and trust page into one sheet and mark each one's rung. Anything still on rung one by Friday is your first rewrite.
Frequently asked questions
What is AI washing?
AI washing is overstating how a product uses artificial intelligence. US regulators, including the SEC in March 2024 and the FTC through Operation AI Comply in September 2024, have acted against such claims.
What should an AI company publish on its trust page?
Training use, retention periods, model and hosting providers as sub-processors, how outputs are evaluated and reviewed, AI security testing, certifications with scope and dates, and a named contact.
How can I prove my AI model is accurate?
Publish dated results on a described test set, with a definition of accuracy and known weak spots, and offer buyers a pilot on their own data with pass marks agreed in advance.
Do certifications help AI startups win enterprise deals?
Independent evidence such as a SOC 2 Type II report or ISO/IEC 27001 or ISO/IEC 42001 certification carries more weight than self-assessment, provided its scope covers the product being sold.
How often should AI trust claims be reviewed?
At least quarterly, and immediately whenever a model, model provider, sub-processor or certificate changes, because each change can make a previously true claim inaccurate.
