Mosaic supercharges global expansion with major market launch and Swiss Re/AXA XL hires

Global specialty insurer  Mosaic is ramping up its global growth plan with its latest launch in Frankfurt, Germany and senior hires from Swiss Re and AXA XL, citing high demand for cyber and transactional liability coverage through Continental Europe.

The Germany office marks the sixth for Mosaic since its launch last year, following those in Bermuda, London, New York, Chicago, and Toronto. Backed by private-equity firm Golden Gate Capital, Mosaic deploys capacity via a global network of underwriting hubs across seven specialty product areas: transactional liability, cyber, political risk, political violence, environmental liability, financial institutions, and professional liability.

Cyber risk specialist Dennis Bertram joins the company as director of Mosaic’s European entity and head of Europe, cyber. Bertram previously worked as a cyber and crime product manager at Finlex, an insurtech specialising in financial lines, and as lead cyber underwriter for Germany, Austria, and Central and Eastern Europe (CEE) at AXA XL. He began his career at Catlin Europe, gaining experience in multiple lines of business, including aviation, casualty, and marine.

The German office will also include M&A specialist Eileen Siemer, who joins Mosaic’s international transactional liability team, and cyber specialist Aron Zeiler.

Zeiler will support the cyber division’s European build-out. He began his career with Swiss Re in Germany, becoming lead underwriter, facultative cyber EMEA (Europe, Middle East, Africa) for Swiss Re in Zurich.

Siemer will underwrite complex and multi-faceted M&A risks to develop Mosaic’s transactional liability business in the DACH (Germany, Austria, Switzerland) region. She joins the firm from RiskPoint, where she underwrote warranty and indemnity insurance in its M&A group. Prior, she served as a corporate associate at international law firms Freshfields Bruckhaus Deringer and Latham & Watkins in Frankfurt, specialising in advising private equity and public and strategic clients on domestic and cross-border M&A transactions, investments, joint ventures, co-investments and management incentives.

Mosaic plans to further expand its presence in Frankfurt over the next 12 months with additional senior hires.

“We’re delighted to welcome Dennis, Eileen, and Aron to build out our reach in Europe, where Mosaic can offer the advantages of Lloyd’s A-plus ratings and much-needed capacity across complex lines of business thanks to both our syndicate and our trade partners,” said the company’s underwriting director, David White.

Bertram said: “We’re thrilled to be able to offer our capabilities and capacity to clients in Continental Europe’s largest and most mature insurance market. Frankfurt represents a vital hub, from which we can serve high client demand, as well as access business opportunities in other markets.”
