Matthew began his career in the early 1980’s, in the London stockmarket.  From there he moved into the fixed income derivatives markets, ultimately establishing his own business, Seagray Fosh Ltd (“SGF”) in 1988 on the London Financial Futures & Options market (‘LIFFE’).During the 1990s, SGF grew to become one of the largest independent brokers on LIFFE, specialising in the equity and fixed income options markets. During the second half of the 1990s, SGF made the transition to full electronic trading, and was subsequently acquired in 2002 by Icap plc.

In November 2002 Matthew moved across from the capital markets to the insurance industry, when he was appointed as CEO of Novae Group plc. He remained as CEO for 15 years before it was acquired by Axis Capital of Bermuda in November 2017.

Matthew remained at Axis for two further years before joining Optio Group in October 2020 as Executive Chairman.
