Buy-side M&A

We advise investors, entrepreneurs, and corporate groups on their acquisition strategies — from sourcing and qualifying targets to executing transactions efficiently and discreetly.


Our approach combines proprietary sourcing methods with deep operational understanding of small and mid-sized companies.


We support both in bonis acquisitions and distressed transactions (“rachats à la barre”) through hands-on coordination with all stakeholders — sellers, legal advisors, and courts.


Our role is to bring structure, discipline, and execution speed to every buy-side process, ensuring deals are sourced intelligently and closed securely.

We advise founders, shareholders, and SME owners in preparing and executing successful exits.


From strategic positioning to process management and negotiations, our goal is to maximize value while preserving control, confidentiality, and continuity.


We understand the specific dynamics of entrepreneur-led and family-owned companies, where financial, personal, and legacy considerations are often intertwined.


By combining investment banking rigor with entrepreneurial sensitivity, we guide each client through a disciplined, tailored process — identifying the right buyers, shaping the right story, and securing the right deal.

Sell-side M&A

Capital Raising & Strategic Advisory

We advise growing companies and their shareholders on equity and debt fundraising, growth financing, and strategic structuring.

Our involvement spans from refining the equity story and preparing materials, to identifying and engaging relevant investors and lenders — venture, private equity, family offices, or institutions.


We help clients build the right capital structure to support their long-term vision, balancing growth ambitions with financial sustainability.


Beyond transactions, we act as a sparring partner on key strategic decisions, ensuring that every financing move strengthens both valuation and future optionality.

Our mission is to help entrepreneurs and investors structure and execute their most strategic transactions from growth financing to full exits.
We bring clarity, confidence, and momentum to complex situations, ensuring that every deal creates real value for all stakeholders.
We act as sparring partners, not intermediaries committed to outcomes, not just processes.
