William Mann

Bill Mann is a seasoned expert in bridging the gap between traditional fundamental analysis and cutting-edge quantitative methodologies. His career in quantitative finance was shaped by a pivotal experience during the 2008 financial crisis at AIG, where he witnessed the dangers of emotional attachment to underperforming investments. This experience sparked his shift from Fundamental to Quantitative analytics, which led him to key roles at Bloomberg and AQR, and ultimately to eight impactful years at Two Sigma.

Throughout his tenure at quantitative hedge funds, Bill led initiatives to optimize alpha modeling throughput by spearheading collaborative research processes that integrated advanced data science and ML/AI capabilities. His unique blend of expertise, underpinned by CPA and CFA designations, enabled him to excel as an industry-specific quant fundamentals analyst, combining fundamental research with quantitative rigor.

As the Co-Founder and Managing Partner of HarmoniQ Insights, Bill now offers his clients a powerful combination of deep industry knowledge and expertise in cutting-edge technology. He empowers fundamental analysts to make confident, data-driven decisions through sophisticated statistical analysis. Leveraging his extensive experience collaborating with quantitative researchers and engineers, Bill is adept at building consensus among senior executives, guiding them to invest with confidence in transformative technologies.

When he’s not driving innovation in the finance world, Bill enjoys playing tennis or spending a day at the beach with his children.
