Paris, June 29, 2026. Fast Growth Advisors announces the launch of the first Message-Market Fit Observatory for French startups, the first study to measure the gap between what a startup means to say and what its market understands. The problem is not technological. It is narrative: across the 83 detailed audits of post-funding startups, three out of four struggle to be understood by their own market.
Take four HR startups. Each has raised several million euros. Hide their logos, line up their taglines, and ask an investor to match each one to its company. They cannot.
That experiment opens the Observatory. The verdict covers 369 companies that raised funds between January 2024 and March 2026: a good product that tells its story badly loses customers and stretches its sales cycles. And often weakens the next round.
What does the Message-Market Fit Observatory measure?
Four questions, which any startup that sells, recruits or raises funds should be able to answer in under a minute: who are you, what do you sell, how do you differ from a competitor, and what concrete value do you bring the customer?
At Fast Growth Advisors, these four answers make up the Point of View (POV).
If even one goes unanswered, on the website or in the pitch, the buyer tunes out.
To check, the Observatory reads only what a prospect would find alone before a first meeting: website, LinkedIn, press articles, funding announcements. What the company says about itself in private stays out of the calculation.
Our measurements across the 369 French post-funding startups give an average score of 5.33 out of 10, and none clears 8. The Observatory page gathers the other key figures and the approach.
Why is it a sentence problem rather than a product problem?
Because the product holds.
All 369 startups studied convinced demanding investors and recruited strong teams. Where it breaks is the translation: turning real technology into a promise a buyer grasps in ten seconds.
And raising money changes nothing.
In Fast Growth Advisors’ measurements, the coefficient of determination (R²) between the amount raised and message clarity is 0.036, a statistically null relationship. A Series B with a generic pitch remains a Series B with a generic pitch.
"We see brilliant companies lose deals against weaker competitors, simply because on the other side you understand in ten seconds what they do, says Hervé Dhélin, founder of Fast Growth Advisors and author of the report. It is not a product problem. It is a sentence problem."
One case among dozens.
A deeptech that raised €30M announces in Les Échos that it cuts production costs by 45%. On its homepage, the visitor reads "innovative advanced recycling solutions". Three procurement directors interviewed could not say what it sells.
A vocabulary analysis confirms the mechanism. Startups that stand out talk about the customer outcome: zero, security, help. Others talk about themselves: projects, development, technologies. The whole shift lives there, from "we" to "you".
Anyone can run the simplest test in five seconds: replace your startup’s name with your competitor’s in your tagline.
If the sentence still holds, you have a problem.
How much does a vague message cost?
In the order of €180,000 in deferred revenue every year for a typical startup, according to Fast Growth Advisors’ calculation. Vagueness shows up in no dashboard. It adds up anyway.
For a typical startup at €2M ARR (annual recurring revenue) with a six-month sales cycle, a pitch that slows the decision represents that amount.
Not lost. Delayed, or captured by a competitor with a weaker product but a sharper message.
This bill lands at three moments. In front of a prospect first: Gartner predicted that 80% of B2B sales interactions between suppliers and buyers would occur in digital channels by 2025, and found that buyers spend only 17% of their time meeting potential suppliers. Website and deck therefore work without a safety net, and if they fail to convince quickly, the cycle stretches. With analysts next: Gartner, Forrester and IDC steer buyers toward shortlists every day, and a startup without a legible positioning cannot appear on them. At exit finally: a value proposition the team cannot repeat internally discounts the perception of commercial maturity, and therefore the valuation.
Where does the vagueness come from? Rarely from copywriting. Almost always from an arbitration nobody made internally.
"When I ask the members of an executive committee to present their company in two sentences, I often feel they work at different companies, says Hervé Dhélin. Each has their own version, their own target, their own argument. The website is not vague by accident: it is vague because internally, nobody has decided."
So the website is only a mirror. It is the most expensive cause, because no homepage redesign fixes it durably.
Why will AI engines widen the gap?
Because B2B buyers increasingly go through AI assistants to shortlist their vendors, and these engines cite the clearest company, not the most visible one. Tomorrow, vagueness will cost differently. In January 2026, Forrester already described generative AI searches as the starting point for B2B buyers.
The Observatory introduces GEO-readiness (generative engine optimization): a website’s ability to be read, summarised and recommended by ChatGPT, Perplexity, Claude or Gemini. French startups cap at 18% of their potential, the lowest score in the entire Fast Growth Advisors study. Unreadable for AI engines today, invisible to buyers tomorrow, whatever the marketing budget.
Finally, a new signal for funds.
The study also compares the portfolios of 25 funds present in at least four startups of the corpus. From one fund to the next, the message clarity of their portfolio companies varies markedly. A signal invisible until now, measurable from now on, that could find its way into upcoming due diligences.
"The best products are not always the ones that raise, observes Alain Sabathier, Business Angel (Provence Business Angels). They are the ones that make themselves understood."

Key figures. 75.9% of the 83 detailed audits of French post-funding startups below the critical message clarity threshold (37.5 out of 75). 18% of potential reached in GEO-readiness, the lowest score in the study.

FAQ
How many startups did the Observatory measure?
369 French post-funding startups, and 83 detailed audits.
All 369 companies raised funds between January 2024 and March 2026, and Fast Growth Advisors read only their public surfaces. The 83 detailed audits, scored on 15 criteria (75 points), are a separate measure: 75.9% of them remain below the critical threshold of 37.5.
What does the critical threshold of 37.5 out of 75 represent?
Half of the detailed audit’s 75 points.
A message scored below 37.5 does not earn half of the points available across the 15 criteria of the Fast Growth Advisors audit. This threshold does not translate into a 6 or a 7 out of 10: the diagnosis, scored out of 10, is a separate instrument.
Does a startup that raises more have a clearer message?
No, and the Observatory data shows it clearly.
Between the amount raised and message clarity, Fast Growth Advisors measures an R² of 0.036: the size of the round explains almost nothing about clarity. Clarity depends on something else: an internal arbitration about who the company is, what it sells and what sets it apart.
