CASUS
Fabian Staub is Co-Founder and CEO of CASUS in Zurich. He studied law in Zurich, Uppsala (Sweden) and St. Gallen. As a lawyer and entrepreneur, he knows both sides: how law firms and in-house legal teams work, and what software has to look like to be genuinely useful there.
Experience and education
Fabian earned his bachelor’s degree (BLaw) at the University of Zurich, and his Master in International Law (MIL) and Master of Law (MLaw) at the University of St. Gallen (HSG). Before co-founding CASUS, he worked as a Research Associate at the HSG and for the Swiss Federal Department of Foreign Affairs (FDFA) at the Swiss Embassy in Canada.
Interviews and profiles
In his interview with the HSG, Fabian talks about how he went from studying law to building CASUS and what he values about working with legal professionals. In his interview with the NZZ, he explains why the future belongs to digital legal services and how AI and legal expertise work together. His Forbes profile (Forbes 30 Under 30) and the article in the St. Galler Tagblatt trace his path from university and the embassy into legal tech entrepreneurship.
Topics at CASUS
On the CASUS blog, Fabian writes about how law firms and in-house legal teams select and successfully adopt Legal AI, where AI concretely helps in everyday legal work, and what matters for compliance and data security. He writes from practice, as a lawyer and as a founder who works on these questions with clients every day.
