A model built on the founders’ reputation

  

The defining characteristic of these investment banks lies in the profile of their founders. They are almost systematically former senior bankers from top-tier financial institutions, having held leading M&A positions for several decades.

These professionals have built their credibility through landmark transactions, a deep understanding of large corporations, and long-standing relationships of trust with executives, family shareholders, and investment funds. Creating their own firm allows them to capitalize on this relational capital and on their personal reputation, which is often stronger than the brand itself.

In this model, clients do not mandate an institution, but an identified, recognized, and highly experienced individual.

     

A radically different advisory approach

     

Unlike large investment banks, these boutiques operate with very lean teams. The number of mandates is deliberately limited in order to guarantee a high level of involvement on each transaction.

The approach is generally more strategic than purely transactional. Founders intervene very early in the decision-making process, supporting executives in long-term reflections: capital structure reshaping, strategic arbitrations, or preparation for a future sale or acquisition.

This proximity translates into a highly personalized advisory approach, far removed from the standardized processes found in large international platforms.

   

A claimed independence

      

One of the key selling points of these investment banks is their total independence. They have neither balance sheets to deploy, nor financing activities, nor ancillary products to sell. Their compensation relies almost exclusively on advisory fees.

This absence of conflicts of interest is particularly valued by certain executives and shareholders, especially in sensitive or complex situations. Advice is perceived as more objective, more aligned with the client’s interests, and less constrained by internal considerations.

This independence also strengthens the credibility of the strategic recommendations put forward.

     

A very specific client base

   

Partner-led investment banks generally target a well-defined client base. This may include large industrial families, executives of listed companies, reference shareholders, or private equity funds involved in complex or atypical transactions.

The operations concerned are not necessarily large in terms of volume, but they often involve a high strategic stake, whether political, industrial, or reputational. It is precisely in these situations that the founders’ experience and judgment make the difference.

   

A demanding environment for teams

   

Working in this type of structure offers a professional experience very different from that of large banks. Teams are small, hierarchies are limited, and exposure to senior executives is immediate.

Junior professionals are often involved throughout the entire process, from strategic analysis to the preparation of client discussions. In return, expectations in terms of quality, intellectual rigor, and confidentiality are particularly high.

It is an environment where the learning curve can be extremely steep, but where the pressure linked to excellence is very real.

    

Atypical career prospects

    

Partner-led investment banks do not offer career paths as structured as those found in large institutions. There are not always formal promotion grids or regular recruitment cycles.

However, professionals who thrive in these environments develop rare skills: strategic thinking, a deep understanding of shareholder issues, and the ability to interact with top-level executives. Such experiences can serve as a springboard to other careers, particularly in private equity, family offices, or within the finance departments of large groups.

For some, the objective is also to commit long-term alongside the founders, within a logic of progressive transmission of capital and responsibilities.

    

Why this model is increasingly attractive

   

In a context where M&A transactions are becoming increasingly complex, politicized, and scrutinized, many executives are seeking high value-added advice, based more on judgment than on sheer execution power.

Partner-led investment banks respond precisely to this expectation. They embody a return to a more artisanal form of advisory work, but exercised at the highest level, where trust and relationship quality prevail over volume.

   

Conclusion

Investment banks such as Zaoui & Co, Raphael Financial Advisory, or Valens Partners occupy a singular position within the M&A ecosystem. Built on individual expertise, independence, and proximity to decision-makers, they offer a credible alternative to traditional large platforms.

For students or young professionals in finance, understanding this model broadens the range of possibilities and opens the door to less standardized, yet potentially highly rewarding career paths, both professionally and intellectually.
