CASUS is the ideal innovation partner for our legal department. The team thinks far into the future while creating meaningful impact in the here and now.
Tereza Jášková, Managing Director & Senior Legal Counsel AI, LegalTech, Data & Cyber Security, Alpiq AG
New software often fails because people do not adopt it. CASUS was quickly embraced by our team because it fits into existing workflows rather than replacing them. That is exactly what I expect from a tool.
Marcel Held, Chief Operating Officer, Domenig Partner
For us as a Swiss law firm, it was non-negotiable: our data stays in Switzerland. CASUS delivers on that without compromise, and with a product that sets the bar.
Dr. Martin E. Looser, Partner, Küng Rechtsanwälte
Yesterday an experiment, today part of how we work, tomorrow indispensable: CASUS.
Avv. Niccolò Salvioni, Owner, Studio Legale e Notarile Niccolò Salvioni
What convinced me about CASUS is not just the technology, but the responsiveness behind it. Whenever I have a question, I hear back from support on the very same day.
Dr. Oliver Fritschi, Partner, Probst Partner
