"One of the few executives in financial services who has personally managed front office trading, large-scale operations, and enterprise technology across banks, exchanges, and investment management firms."
Mat Small is the Managing Partner of AntePartners and brings more than 30 years of senior leadership across capital markets, banking, and technology. His career is distinguished by hands-on authority across three domains that most executives manage only one of: front office trading, operations, and technology. His traded product experience spans fixed income, mortgage-backed securities, equities, warrants, and derivatives. This front-to-back perspective, combined with genuine cross-institutional experience at global banks, a major US securities exchange, and a large government-sponsored investment management enterprise, enables him to benchmark approaches and design solutions that reflect best practice across the full spectrum of financial services.
At Citicorp, Mat built deep fixed income and structured products expertise in the MBS division before being deployed to Frankfurt, Germany for over two years, where he managed Citibank's European Warrants and Derivatives businesses end-to-end. He subsequently spent more than two years in London at Citicorp's Global Corporate Investment Bank managing cross-business transformation programs across European and global markets. At the American Stock Exchange, based between Stockholm and New York, Mat led the architecture and delivery of the Exchange's next-generation electronic trading platform before restructuring the entire technology organization, reducing a $168 million budget by 24% within 16 months. At Fannie Mae as Senior Vice President, he led the largest transformation in the history of one of the world's largest GSEs. The program fundamentally changed how the business managed its capital markets portfolio, redesigning all business processes for real-time trade management alongside the implementation of a new trading platform, full securities accounting infrastructure replacement, operations outsourcing, and enterprise data strategy. The outcome was a measurably more capable organization: accounting close cycles compressed from weeks to days, operating costs reduced, and a real-time analytics platform created whose underlying methodology was subsequently replicated across multiple enterprise initiatives.
In professional services, Mat served as a Partner at both Capco and Ernst & Young's Financial Services Advisory practice, advising C-suite and board-level clients on transformation strategy, regulatory governance, and risk frameworks. At AntePartners, his engagements span regulatory health assessments, model risk framework design, regulatory findings and enforcement action remediation, large-scale program turnaround, data and analytics transformation, and fractional C-suite leadership. His international operational experience across the US, UK, Germany, and Sweden makes him particularly well-suited to advising global banks navigating complex, cross-border challenges.
