Mosaic names former Ironshore exec Wheeler as co-CEO
Mark Wheeler has been reunited with his old friend Mitch Blaser, with whom he worked at Ironshore, having been named as co-chief executive officer, alongside Blaser, at Bermuda-based specialty insurer Mosaic.
Wheeler has served in a variety of leadership roles in a career that spans more than three decades, having founded Lloyd’s Syndicate 4000 and Pembroke Managing Agency, which was purchased in 2008 by Ironshore.
He also served as CEO of Ironshore International, managing creation of high-profile consortia and expansion to 14 countries. He later held executive roles in global client engagement and international markets for Liberty Mutual Group, following its 2017 acquisition of Ironshore.
Mosaic launched in February 2021 and focuses on selected insurance lines with global relevance and growth trends. It has already begun underwriting war, terror and political violence coverage, as well as political risk liability, and cybersecurity.
It combines Lloyd’s Syndicate 1609 with a wholly-owned syndicated capital management agency and underwriting hubs in Bermuda, London, the US and Asia.
Wheeler said: “Mosaic is a highly discerning underwriting business with lead-market capabilities, and we are entirely focused on generating outstanding value for our clients.” The appointment is subject to work-permit approval.
