Who writes the Fast Growth Advisors blog, and with what data?
Hervé Dhélin, founder of Fast Growth Advisors, signs the articles on this blog.
Behind him, the Message-Market Fit firm brings together three partners and more than thirty years of B2B marketing. Articles draw on what we see in engagements, on what our audits measure, and on what AI engines actually do with a B2B website.
Figures specific to the firm mostly come from the Message-Market Fit Observatory: edition No. 1 (Q2 2026), 369 French post-funding startups measured, average score 5.33 out of 10, none above 8. Across the 83 detailed audits, 75.9% remain below the critical threshold of 37.5 out of 75. External data links to its primary source, cited in the article itself.
In short: measure first, write second.
