Your questions about Prouesse

The questions founders and executives ask us most often.

Another question? Write to us →
From what deal size does Prouesse get involved?

Prouesse works on transactions from €2m, with no ceiling: Series A fundraising and beyond, company sales and M&A, structured debt. This threshold guarantees a complete process (valuation, documentation, competitive tension, negotiation) with the intensity this kind of transaction demands.

What is the difference between an investment bank and a fundraising broker?

A broker introduces you to investors. An investment bank like Prouesse runs the transaction end to end: valuation, equity story, structuring, a competitive process, term sheet negotiation and support all the way to closing. Introductions are only one step: execution is what sets the final price and terms.

Does Prouesse work with impact funds and family offices?

Yes. Prouesse works directly with impact funds, private equity funds, family offices and corporates, in France and internationally. For sellers and founders, we run competitive processes; for investors, we bring qualified, structured deals that are ready for due diligence.

How long does a mandate with Prouesse last?

For a company sale (M&A), allow 2 to 4 months to test market value and identify buyers, then another 3 to 6 months to closing. For a fundraise, the process takes 6 to 9 months on average. Prouesse only takes on deals the team can see through to closing.

How many investors or buyers does Prouesse approach per mandate?

A qualified list of 30 to 60 counterparties per mandate. The typical funnel: around 50% response rate, ~10 NDAs signed out of 25 respondents, and 1 to 3 firm offers (rates observed on our past mandates, not a guarantee of results). The list is split between solidarity/impact investors and mainstream investors to maximise the match.

How does Prouesse avoid greenwashing when selecting counterparties?

Systematic pre-qualification on three criteria: (1) financial capacity, (2) genuine strategic interest, (3) authentic impact alignment. Nothing goes out without the client's approval. Every approach to a potential investor or buyer is made with the founder's explicit consent. Together with the client, Prouesse rules out purely opportunistic counterparties to protect the mission of the companies we support.

What is Prouesse's fee model?

A mix of a low monthly retainer + success fee. The low retainer commits Prouesse to the mandate and ensures the client is committed to the process too (a mandate is a two-way job). Prouesse earns its living from success fees: our interests are fully aligned with the client's, and we only succeed if the client does.

What is the difference between an investment bank like Prouesse and an M&A lawyer?

Prouesse (investment bank): strategic guidance on valuation, market practice, identifying and qualifying counterparties, and negotiation. Acts as a buffer in difficult conversations (price, terms, post-deal roles) to protect the relationship between the founder and their future partner. M&A lawyer: legal drafting of the SPA and the shareholders' agreement once the LOI is signed, protection on earn-out and warranty and indemnity clauses. The two roles are complementary and both essential.

How many deals does Prouesse handle each year?

5 to 7 deals a year. It is a deliberate boutique choice: the Prouesse team wants close involvement in every mandate rather than industrial volume. Every client has direct access to the partners from start to finish, and gets tailor-made materials (deck, business plan, data room).

Which sectors and regions does Prouesse cover?

Mainly France (SMEs and mid-caps), with specific expertise in emerging markets (Madagascar, sub-Saharan Africa, Corsica). Sectors covered: circular economy, healthcare, inclusion (disability employment, work-integration enterprises, accessibility), agritech, green data centres and sustainable infrastructure, impact real estate, transition energy, and the transfer of mission-driven companies.

When should you call Prouesse rather than wait?

As early as possible. Prouesse helps structure the business plan so it is investor-ready, weigh equity against debt or a sale, and avoid positioning traps (the wrong amount, the wrong sequence of investors, an off-market valuation). A first 30-minute call qualifies the strategy, with no commitment.

Can Prouesse help even if we're not yet sure we want to raise or sell?

Yes. Prouesse first helps clarify the strategic decision: raise to accelerate, sell to pass the business on, or structure a hybrid deal (partial sale + reinvestment, OBO, management LBO). Several founders came in with a precise idea and left with a different mandate, because it was the best option for them, their business and their impact.

What is Lévaia and how does it fit with Prouesse?

Lévaia (levaia.fr) is a free tool built by Prouesse to help founders estimate their valuation, benchmark themselves against the market and prepare for a transaction. It includes a scoring tool, an AI coach and investor-readiness modules. Lévaia is the self-assessment step; Prouesse then steps in to execute the mandate.
