In September 2009, amidst the shifting dynamics post-Financial Crisis, Alex founded GFC, noticing a significant trend: companies were transitioning their capital financing from loans to bonds, prompting closer collaboration between banks' loans and bonds teams. GFC debuted its inaugural Bonds & Loans event in June 2010 in Dubai, drawing nearly 180 key players from the capital markets.  By 2023, the Dubai event was attracting over 1,500 attendees, and annually, more than 5,000 senior banking and markets professionals gather at GFC’s five events across Dubai, Riyadh, Miami, Istanbul, and Cape Town.  In 2024, Alex spearheaded a successful management buyout of GFC and took the helm as CEO of Turnmill. Before launching GFC, Alex gained diverse experience in media, research, and events. He holds a degree in Economics and Finance from the University of Durham.
