Team
After working together for over a decade, we founded QML Solutions in 2024 to bring our quantitative expertise directly to clients. Together, we combine decades of experience in quantitative research: building models, communicating them to investors, and producing strategy research. QML Solutions is our way of sharing our quantitative, data-driven insights into credit and equity markets. We believe quant research can be both rigorous and accessible, and our goal is to provide insights and tools that are immediately actionable.
