Collaborative and commercially grounded
We specifically chose Punter Southall because of their deep bench of expertise in AI and data regulation, but what truly set them apart was how they applied that knowledge in a practical, forward-thinking way.
The team didn’t just advise, they challenged our assumptions and helped us reframe how we approach data protection and AI, both internally and in our client offerings. Compared to other firms we’ve worked with, their approach felt more collaborative and commercially grounded, rather than purely compliance-driven.
Their ability to translate complex regulatory issues into actionable strategy was particularly impressive.
