About BLAAK Underwriting Agencies
At BLAAK Underwriting Agencies, we share the entrepreneurial mindset that defines the DUPI Group: practical, involved and always focused on workable solutions. We don’t believe in standard solutions because maritime operations aren’t standard either. Every risk is different. That means underwriting should be approached differently as well. No standard solutions, but tailored thinking, creative problem-solving and a focus on what is possible.
As part of the DUPI Group, BLAAK operates alongside DUPI Underwriting Agencies. This parallel positioning strengthens the group’s marine proposition. DUPI provides a broad, multiline offering; BLAAK adds depth by focusing on niche and complex maritime risks. Different focus, same mindset: practical, involved and solution-driven.
