Mosaic Insurance has announced the opening of an office in Frankfurt Germany as it seeks to expand its global reach and meet demand for cyber and transactional liability coverage in Continental Europe.
This new office is the sixth opened by the specialty insurer since its launch early last year, having already established operations in Bermuda, London, New York, Chicago and Toronto.
Mosaic’s Frankfurt business will be led by Dennis Bertram (pictured above, centre), who has been appointed as director of the European entity and head of Europe, cyber. He will be accompanied by cyber specialist Aron Zeiler (pictured above, left) and M&A specialist Eileen Siemer (pictured above, right), with additional senior hires planned over the next 12 months.
Bertram joins Mosaic after working as a cyber and crime product manager at insurtech Finlex and as lead cyber underwriter for Germany, Austria, and Central and Eastern Europe at AXA XL. Starting his career at Catlin Europe, he has gained experience in multiple lines of business such as aviation, casualty, and marine.
Zeiler, who is coming into Mosaic as part of the international transactional liability team, will support the cyber division’s European build-out. He began his career with Swiss Re in Germany, later becoming lead underwriter, facultative cyber EMEA (Europe, Middle East, Africa) for Swiss Re in Zurich.
Siemer, meanwhile, joins the Frankfurt team to underwrite complex M&A risks and develop Mosaic’s transactional liability business in Germany, Austria, and Switzerland. She previously worked at RiskPoint, where she focused on underwriting warranty and indemnity insurance in its M&A group. She was also a corporate associate at international law firms Freshfields Bruckhaus Deringer and Latham & Watkins in Frankfurt, specialising in advising clients on domestic and cross-border M&A transactions, investments, joint ventures, co-investments and management incentives.
“We’re thrilled to be able to offer our capabilities and capacity to clients in Continental Europe’s largest and most mature insurance market,” said Bertram. “Frankfurt represents a vital hub, from which we can serve high client demand, as well as access business opportunities in other markets.”
Mosaic launched in February 2021, backed by private equity firm Golden Gate Capital. It has since established a global network of offices that offers services across seven specialty areas, namely transactional liability, cyber, political risk, political violence, environmental liability, financial institutions, and professional liability.
