Your portfolio’s Message-Market Fit is an asset. Measure it.
Fast Growth Advisors measures the Message-Market Fit of your portfolio, then brings it back up to standard. The methodology comes from the Message-Market Fit Observatory 2026: 369 French post-funding startups, average clarity score 5.33 out of 10. You assess the product, the team and the market. Traction depends on what the market understands.
Paris Business Angels and Fast Growth Advisors join forces.
Companies in the network’s portfolio get a detailed messaging audit against fifteen criteria, with a 90-day action plan. For new deals, a messaging score becomes part of entry due diligence. Read the press release →
In short
- Fast Growth Advisors helps funds and business angel networks accelerate portfolio value through message clarity.
- The 2026 Observatory shows it: the correlation between the amount raised and message clarity is close to zero (R² = 0.036).
- Each portfolio company gets the full 15-criteria audit, at preferential terms for the portfolio.
- A clear message shortens sales cycles and makes the next round easier to read for follow-on investors.
01Why
Why audit the Message-Market Fit of your portfolio?
Because your capital sometimes funds a narrative the market does not understand. Raising funds does not make the message any clearer: the problem will not fix itself with the next round.

gap: the variable is observable, uneven, and measurable at portfolio level
What this gap does not say: that one fund is better than another. Source: Fast Growth Advisors Observatory, Q2 2026.
Series C and D funds now factor positioning clarity into their commercial due diligence, alongside NPS (Net Promoter Score) or churn. A portfolio company scoring below 40/75 will still raise: at a discounted valuation. We estimate that risk premium at 15 to 25 percent.
Across a portfolio, it is the cheapest variable to fix. No product overhaul, no hiring, no extra round.
And it can be measured before you commit to anything: the diagnostic is free, the audit takes 48 hours after the interviews.
The Message-Market Fit Observatory 2026 measured 369 French post-funding startups: an average clarity score of 5.33 out of 10, none above 8. Across its 83 detailed audits, 75.9% stay below the critical threshold of 37.5 out of 75. Explore the Observatory
02What we offer
What do we offer investors?
Fast Growth Advisors offers three levels of engagement, from a one-off diagnostic to a portfolio-wide programme. The last two are decided after the audit, never before.
Entry point
The portfolio company audit
We apply our messaging audit to one portfolio company: it scores 15 criteria and 5 AI visibility layers, based on interviews with the executive team, and the report is delivered 48 hours after the interviews. It costs €2,000 excluding tax per company, and the debrief is held jointly with the startup and the investor.
If the gap is confirmed
The rebuild
Our team rebuilds the positioning and the message in 2 days on average, then guides its deployment across the company’s assets.
For a portfolio

04Who for
Which investors is this for?
Business angel networks
You want to equip your members with a shared measure, on portfolio companies already in market.
European B2B funds
You want an objective read on a signal board meetings never measure: what the market understands of the portfolio company’s narrative.
Business angel networks and European B2B funds work with Fast Growth Advisors on portfolio companies already in market. This approach assumes a working product and first customers: it measures what the market understands, not whether the product has found its market. A score below 40 out of 75, the one the audit surfaces, is the warning signal. A free diagnostic settles it in minutes, before any commitment, on a single company as on the whole portfolio. That first read commits neither the investor nor the portfolio company.
Frequently asked questions
Does the portfolio company have to be on board?
Yes. An audit by Fast Growth Advisors works with the executive team and never against it, since the interviews with the CEO, the marketing director or the CTO are its raw material, and the report is shared with them at the same time as with you, which removes any information asymmetry between the two sides. In practice the approach is well received.
Who receives the report?
Startup and investor receive the same report, presented in a joint debrief. Across a portfolio of several companies, we add a comparative summary: strengths, recurring gaps and action priorities at portfolio level. Thanks to this joint debrief, no report circulates without the portfolio company knowing its content.
How much does a portfolio company audit cost?
Count €2,000 excluding tax per company (the individual audit is €3,000), with the report delivered 48 hours after the interviews. Partner networks and multi-company portfolios get packaged terms, defined by agreement at portfolio level. For a network, Fast Growth Advisors applies the same deliverables as the individual audit, at a negotiated rate, and scores stay comparable from one company to the next. As for the prior diagnostic, it stays free and carries no commitment: it is what decides which portfolio companies deserve a full audit.
How does the portfolio company move forward after the audit?
Either the company executes the action plan on its own, or it is supported: repositioning in 2 days on average, then guided deployment. Progress is tracked by the investor through the action plan milestones, without stepping into the execution. Both options are decided after the debrief, never before, and the investor keeps visibility on the milestones either way, whichever path the portfolio company chooses.
