Jean Hermelin

Descartes Underwriting has appointed Jean Hermelin as chief strategy officer, as it looks to accelerate growth and expand its position in parametric re/insurance.

Hermelin (pictured) joins the executive committee in a newly created role, reporting to CEO and co-founder Tanguy Touffut, with responsibility for defining and executing group strategy.

His remit includes identifying new growth opportunities and improving operational and commercial efficiency as the firm targets $500m in premiums by 2028.

The appointment follows a period of strong growth, with Descartes surpassing $250m in premiums in 2025 and expanding its international footprint, particularly in North America and Asia Pacific.

Hermelin brings more than a decade of experience from Oliver Wyman, where he led transformation and commercial strategy programmes for global insurers.

His experience spans business development, partnership strategy and operational improvement, supporting Descartes’ focus on scaling its parametric offering.

The firm has continued to develop new products across climate, cyber and emerging risks, including solutions for data centres and flood exposures, alongside the expansion of its parametric reinsurance capabilities.

Descartes said the appointment will support further innovation and strengthen execution as it scales its business model globally.
