Sentinel Legal does not position itself as a generalist firm. Our law firm operates exclusively in targeted and mastered areas of expertise, notably criminal law, new technologies, business law, and civil litigation, integrating a deep understanding of cross-border (CH-EU), operational, and economic dimensions into every mandate.
Our size is an advantage: every case is handled by a partner, never entirely delegated. You benefit from a single, experienced point of contact who understands your situation in its entirety and is fully invested in achieving a result.
Our two founders, Mr. Matthias Traussnig and Mr. Aurélien Rocher, combine experiences directly useful to their clients: practice in law firms, the Public Prosecutor’s Office, Big Four, university teaching, and immersion in technological ecosystems — Legal Tech, AI, Web3. A combination that grants them pragmatism, high standards, and a multidisciplinary perspective on the most complex situations.
We only accept mandates that correspond to our expertise. No dispersion, no compromise.
Legal. Economic. Strategic. Your interests, in their entirety.
Your reality first. Not a legal text applied to a standardized file.
