01The scope
What does the messaging audit measure?
Everything that makes a message sell or fail, from positioning to how citable you are for AI engines. Here is where French startups stand on each of the 15 criteria.
Reading: GEO readiness closes the ranking at 0.91 out of 5, i.e. 18% of its potential. Source: Fast Growth Advisors Observatory, Q2 2026, methodology of the Message-Market Fit Observatory.
These criteria measure Message-Market Fit: definition, measurement and Observatory data.
Five AI visibility layers come on top of the fifteen criteria. That is the part your competitors are still ignoring.
First from everything a prospect sees before calling you: your website, your LinkedIn, your press coverage, your funding announcements. Then from interviews with your CEO (Chief Executive Officer), your CPO (Chief Product Officer) and your CMO (Chief Marketing Officer).
That is where the proof, the numbers and the convictions that are written nowhere actually live. Almost always, the raw material exists. It has simply never left your heads.
That is the difference with the Fast Growth Advisors Observatory, which only audits what is public: the audit goes after what you already know and your market does not. The five AI layers cover content clarity, semantic HTML, Schema.org structured data, AI crawl directives and agent comprehension.
In September 2026, Fast Growth Advisors won the “Best B2B Message-Market Fit Consultancy 2026, Europe” category of the LeadGen & Sales Performance Awards, run by the British magazine Acquisition International. According to the organiser, the jury looks at measurable impact and client success. Our audit rests on the same demand for measurement: a score across 15 criteria and five AI visibility layers, then what to fix first. Measurement comes before the fix. Read the press release →
02The deliverable
What do you actually receive?
At Fast Growth Advisors, there is no generic advice: every single finding of the audit is illustrated with your own pages and your own sentences, never with a textbook example.

03The process
One week between the first interview and the debrief. Fast Growth Advisors keeps human interpretation where it matters: reading the gaps, ranking them and turning them into recommendations for your teams.
Interviews
One hour with each relevant executive: CEO, CMO, CPO or CTO (Chief Technology Officer). That is where the narrative gaps surface.
Analysis
Your website, your content and your presence in AI answers run through our audit technology, then through human review.
Report
Delivered 48 hours after the last interview.
Debrief
One hour to walk through the findings and decide what comes next.
04What comes next
Who fixes the message after the audit?
Every debrief ends with a decision: fix the message yourselves with the action plan, or hand its rebuild to Fast Growth Advisors.
Option 1
You fix it in-house
The action plan sets the order of work. Your teams apply it without us.
Option 2
Message-Market Fit consulting
If the audit confirms the gap, we rebuild your message in two days on average, then get the whole team to adopt it, from the CEO to the sales rep. The price of the engagement is set case by case, depending on the scope.
05Who it is for
The Fast Growth Advisors messaging audit is built for European B2B startups and scale-ups, and for the investors who back them.
B2B startups and scale-ups
A strong product, a pipeline that does not follow.
Executives
You sense that every sales rep tells a different story, and that the website tells a third one.
Investors
Do you invest in B2B startups? We give you an objective read on your portfolio companies’ messaging, and packaged offers exist for business angel networks as well as for funds that want to cover several companies at once.
Frequently asked questions
How much does the audit cost and what does the price include?
€3,000 excluding VAT, all inclusive: the interviews, the full analysis across 15 criteria and 5 AI layers, the report and the one-hour debrief. No strings attached: the report is yours, you do whatever you want with it. If you decide to go further, the engagement is decided after you have read the report.
Why does the report arrive in 48 hours?
Because the analysis is industrialised by our own technology, the same one used to measure 369 startups for the Observatory. Human expertise stays where it matters: interpretation, prioritisation and recommendations. Those 48 hours run from the last interview, not from the order.
Can we fix it ourselves?
You can execute the action plan internally. If you would rather be supported, the Fast Growth Advisors team rebuilds your positioning and message in 2 days on average, then guides your teams to deploy it across your assets: website, sales deck, content, campaigns. Either way, the report works as a roadmap, with gaps ranked by severity and an order of correction already decided, so nobody has to start again from a blank page. In both cases, the report remains entirely yours.
How does a messaging audit differ from a classic B2B marketing audit?
A classic B2B marketing audit reviews channels, budgets and results. The Fast Growth Advisors messaging audit starts upstream: it measures what your market understands of your offer, across 15 criteria and five AI visibility layers. Both complement each other. On the message side, the audit tells you what to fix before investing more in channels.
Does the audit cover visibility in ChatGPT and Perplexity?
Yes. Five analysis layers measure how citable you are for AI engines: content structure, semantic HTML, Schema.org, crawl directives and agent comprehension. You know whether AI can understand you, extract you and recommend you. That is the part your competitors are still ignoring.
