two partners
- no more, no less
For such highly technical matters, we have opted for a small team: your cases are always handled by one, the other, or both of the firm's partners. This guarantees that you will receive expert advice and individual support at all times.
Adrien and Mathias were both trained in international law firms; they work in both French and English and are members of the Support Pool of Experts of the European Data Protection Board.
The firm's expertise in data protection, cybersecurity, and platform law has been recognized every year since 2023 by the Leaders League ranking.
When we are not busy defending our clients' interests, we find pleasure in engaging in legislative and societal discussions on the law, and sharing our knowledge through publishing and academic activities.
We are blessed with the honor of writing for leading legal journals and the general and specialized press, aimed at both other lawyers and the general audience.

our commitments
Low environmental impact
Digital sobriety, second-hand furniture, train travel, paperless work — we are constantly working to reduce the environmental impact of our business.
Data security
We take a lot of care in securing our clients' data. We host it in our own environment; only our emails are hosted externally, in Switzerland, and are subject to zero-access encryption.
Social engagement
We give dozens of hours each year to public interest organizations who work to protect the environment and biodiversity.
The 1% rule
One percent of all our profits is donated to charities that share our values — the French League for the Protection of Birds for Adrien and Emmaüs Connect for Mathias.
