Friends reunited as former Ironshore exec Wheeler named as co-CEO at Mosaic

13-04-2021

Mosaic Insurance has appointed Mark Wheeler as co-chief executive officer (CEO), to work alongside fellow co-CEO Mitch Blaser. 

Wheeler has served in a variety of leadership roles in a career that spans more than three decades. He was the founder of top-quartile Lloyd’s Syndicate 4000 and Pembroke Managing Agency, which was purchased in 2008 by Ironshore, where Blaser was a founding executive. 

Wheeler 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, combining Lloyd’s Syndicate 1609 with a wholly-owned syndicated capital management agency and underwriting hubs in Bermuda, London, the US and Asia. It is focused on selected insurance lines with global relevance and growth trends, and plans to launch specialty products throughout 2021. It has already begun underwriting war, terror and political violence coverage, as well as political risk liability, and cybersecurity.

Dan Haspel, a managing director at Golden Gate Capital, Mosaic’s anchor investor, highlighted Wheeler’s industry relationships and deep market knowledge as assets to Mosaic.

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.
