About us

Our firm/ we believe – we behave

More value.

Our firm was created with a unique value proposition of providing a holistic approach in Transaction Services, by combining law and financial due-diligence expertise.

More trust.

Over the past five years, we earned the trust of our clients, with the highest levels of expectations, and have succeeded in setting new standards in due diligence.

More input.

Our mission is to build on this double vision to go beyond raw analysis and put more skin in the game by giving recommendations and helping our clients to implement them in post deal context.

More perspective.

With the skillset of our talents and our in-house methodology, we have the conviction that we can help build new referentials through the deep understanding of emerging business models.

We anticipate evolutions. We never yield. We make an impact beyond Transaction Services.
