    Bill Mann

    CO-FOUNDER & MANAGING PARTNER

    Bill Mann is the Co-Founder and Managing Partner of HarmoniQ Insights, a micro VC fund investing at the intersection of data, finance, and technology. A CPA and CFA, Bill has built his career on bridging fundamental investing with quantitative research, holding leadership roles at Bloomberg, AQR, and Two Sigma.

    At Two Sigma, he spent nearly a decade leading initiatives to scale alpha modeling and integrate ML and AI into the firm’s research workflows. Known for his ability to translate domain expertise into quantitative systems, Bill developed collaborative research processes that aligned PMs, data scientists, and engineers around shared models of risk and return.

    His shift from fundamental to quantitative investing began during the 2008 financial crisis at AIG, where he saw the cost of emotional bias in portfolio construction. Since then, Bill has helped institutional teams adopt data-driven decision-making with precision and discipline.

    Outside of HarmoniQ, Bill is a mentor to early-career quants and a dedicated tennis player who enjoys spending time at the beach with his family. Bill is the 2025 reigning doubles champion at his club.
