Hintze UK Ltd. - providing U.S. legal support in the UK and European market  

We provide our UK and European clients with practical and actionable advice on U.S. AI, privacy, and cybersecurity laws.  We are pleased to offer these services from our London office to better service our international clients in European time zones. 

The London office is led by Sam Castic, a U.S. licensed lawyer, and operated by Hintze UK Ltd. a wholly owned subsidiary of Hintze Law PLLC. Since its founding in 2014, and built exclusively around the complexities of privacy, AI, and cybersecurity law, Hintze Law combines deep legal, technical, and business expertise to help clients navigate evolving regulatory landscapes with confidence and clarity.   

As U.S. data governance laws become increasingly complex, and U.S. litigation and enforcement grows, we help our UK and European clients achieve their U.S. business and growth objectives with right-sized approaches for the U.S. market.
