Highly specialized team of professionals and advisory board

Our professionals bring a unique and valuable combination of international perspective and sector expertise, developed over decades of advising in M&A and corporate transactions for the life sciences vertical and other interesting industries; experience in structuring and closing complex financial deals; and strong relationships with industry professionals globally.


Our services are offered by professionals who have done it before.

We have received many “no’s”, have seen many deals fail in the last minute at the notary, and dealt with many stakeholders that complicated rather than facilitated the deal process.

But above all: We have successfully closed many transactions and financing rounds. We know how to make a company “sellable” and a startup “investable”. We have written many Teasers, equity stories and Memorandums. We know how to put your strengths into the spotlight, and how to deal with your weaknesses. And last but not least: We have a deep target and investor network in our specific industries.
