Main Contact : Grégoire Mangeat (

CLIENT: Francesco Abbate, Managing Partner
COMPANY/FIRM: Swiss Crypto Advisors SA
TESTIMONIAL: “We have been using the services of Mangeat Attorneys since the launch of our business especially for strategic advice in banking & finance, anti-money laundering and corporate law, and of course for our STOs-related activities, mainly with Fabien Aepli, Nurith Cohen and Diego Leis. Their knowledge of Swiss financial regulations applicable to blockchain and cryptocurrency projects is essential to us. Their professional support and high-quality advice are extremely appreciated by our team. They are responsive, pragmatic and technically skilful. Also, they are very clear and transparent with regard to their fees. For these reasons, they participate in business meetings, understand the ultimate business goals and hence tailor the right legal advice and consultancy to ultimately create value for us and for our clients; I see this as a shift from a “cost of doing business” to “business investment yielding returns”.”

CLIENT: Gilles Bos, Chairman
TESTIMONIAL: “Mangeat Attorneys have been active in the medical device industry for many years, and they regularly assist us on commercial agreements (distribution agreements, manufacturing agreements, technology transfers, etc.), asset and share deals, corporate governance, regulatory issues and dispute resolution. Our main contacts are Fabien Aepli and Nurith Cohen for commercial and corporate matters, and Grégoire Mangeat and Sara Dousset for regulatory matters and dispute resolution. Their knowledge of the industry, their legal skills and their commitment to deliver excellent work in a consistent manner are highly valuable and appreciated assets for our business. They are efficient, pragmatic and business-oriented.”

CLIENT: Samer Darwiche, CEO
TESTIMONIAL: “The quality level of the work that Mangeat Attorneys provide clearly reaches the level of the first-tier big firms with which I have worked so far. The firm does also have an outstanding professional approach and sense of the client relationship.”

When building a powerful reputation, and with the dedication to deliver outstandingly, it is essential to always keep in mind the moral obligation to act responsibly and ethically, to produce an overall positive impact on society.

At MANGEAT we believe in the importance of Corporate Social Responsibility, especially in our capacity as attorneys at law.

Therefore, we are involved in various pro bono and volunteer activities, be it to defend the access to justice or to seek better systems of justice.

Our pro bono work goes beyond the traditional representation of people with limited resources. The importance of Law is growing on a daily basis and with that our responsibility to address the pressing challenges that ensue.

We aim to truly make a difference and address problems such as unequal access to justice, devastation caused by conflicts and massive immigration waves that follow, global health threats and of course important human rights issues (for instance with members or our team participating in the Geneva Human Rights Commission).

Our volunteer activities also include commitments beyond the legal community. For instance, to actively support charitable organisations.
