The firm: Based in Geneva, Switzerland, MANGEAT is a dynamic law firm helping clients to achieve their ambitions in today’s complex and fast-changing world.

When it was founded in January 2016, the firm brought to its clients the benefit of working with an already fully formed and experienced team. Its three founders, Grégoire Mangeat, Joël Chevallaz and Fabien Aepli, had all worked together for more than a decade and all their current senior associates followed them from Eversheds Sutherland Switzerland.

The entire team aims to challenge the status quo while delivering solutions and results that exceed the clients’ expectations. To mitigate risks and seize opportunities, the firm gives the highest importance to the continuous education and training of its team. Combined with an agile mindset and a permanent team-oriented approach, this enables its attorneys to compete with the top practices in the country. In order to better deal with the increasing complexity of a more connected and global landscape, the firm also developed a network of more than 250 lawyers in most jurisdictions over the world, allowing it to assist its clients in all types of cross-border activities.

MANGEAT aims to be at the forefront of the legal profession by always thinking ahead, implementing innovative tools and offering a seamless collaboration between a wide range of talents, both within and outside the legal world.

Areas of practice: The firm’s core service lines include banking and financial services, corporate and commercial, dispute resolution, employment, fraud and financial crime, real estate and restructuring.

The firm helps its clients to face the evolving market norms and the many challenges that arise such as obtaining required authorisations from the supervisory authority, ensuring compliance with legal, regulatory and internal duties, amending internal documents and general terms and conditions, and anticipating coming regulations.

After adding a new partner to its litigation team in 2017, the firm now offers a dedicated Spanish and Latin American desk for Spanish and Portuguese-speaking clients.

For corporate clients, MANGEAT provides creative, customised and cost-effective services in organisational matters and transactions taking place in the specific industries its clients operate in. This includes compliance, corporate governance, mergers and acquisitions, due diligence, corporate reorganisations and shareholders agreements. On the commercial side, this includes negotiating, drafting and reviewing commercial contracts for domestic and cross-border transactions as well as general terms and conditions.

In data protection matters, two of the firm’s senior associates are now Certified Information Privacy Professional/Europe (CIPP/E).

The firm also combines skills from different practice areas that cover employment law, including corporate, contract and dispute resolution with experience in both private employment and public labour law.

In real estate matters, the firm’s main activities include real estate development, finance and securitisation, sale and leaseback transactions, environmental matters, permits for acquisitions of real estate and second home-related aspects. In 2017, the firm strengthened its ability to provide solutions in structuring and executing complex transactions with the addition of a new partner specialised in real estate and construction matters.

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 Attorneys at Law 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.
