FOUNDERS

James Karim and Frederik Eloff co-founded Re Square in September 2018. They previously worked together as two of the team of five portfolio managers at Deutsche Bank’s start-up Insurance Opportunities Fund.

JAMES KARIM

James started his reinsurance career at broker Guy Carpenter in 2000, after which he held a series of actuarial modelling roles at both reinsurers and reinsurance brokers. From 2010, he spent almost five years working in Aon’s reinsurance broking business, before joining Deutsche Bank. James qualified as a UK actuary in 2003 and holds a double-first-class degree in Economics from Christ’s College, Cambridge University.

FREDERIK ELOFF

Frederik started his actuarial career in product development at Zurich Financial Services. He moved into the ILS space in 2005, joining Securis Investment Partners prior to its launch. At Securis, he was involved in most aspects of portfolio management and pricing in both the life and non-life sectors. He was also responsible for designing, building and implementing Securis’ portfolio aggregation software. Frederik qualified as a UK actuary in 2006 and obtained an Honours degree (with distinction) in Financial and Actuarial Mathematics.
