David Rosenzweig Is Latest in Series of Leadership Hires as Company Posts Strongest Quarter Since Inception

SCOTTSDALE, AZ – March 21, 2022 – A twenty-five-year veteran of financial services and recent CFO within Global Atlantic insurance company, David Rosenzweig has been appointed Chief Financial Officer of Ategrity Specialty Holdings and its subsidiaries. Rosenzweig, who has been a consultant with the company since last year, now joins the leadership team full-time as Ategrity posts a record 17% annualized return on equity for Q4 2021. Ategrity launched in 2018, focusing on the excess and surplus (E&S) lines market, and in 2021 received $75 million in capital from Sequentis Financial LLC.

“David brings to Ategrity an outstanding breadth of financial expertise and operational transformation,” says Deputy CEO Justin Cohen. “His leadership will continue our drive to even greater performance going forward.”

Rosenzweig’s appointment as CFO is the most recent in a series of new hires bolstering the company’s strength in enterprise risk management (ERM) and best-in-class data and analytics. In 2021, Benjamin Martin, Head of Exposure Management, joined Ategrity from Sompo International, preceded by positions at Insight Catastrophe Group and 11+ years at specialty insurer Hiscox. Ashley Zayas, Ategrity’s new Head of Data, also worked at Hiscox.
