William von Mueffling

William von Mueffling founded Cantillon Capital Management after leaving Goldman Sachs, naming the fund after Richard Cantillon, the 18th-century Irish-French economist credited with founding monetary theory. Von Mueffling built Cantillon into a rigorous global long/short equity manager with a disciplined investment process combining thorough fundamental research with careful portfolio construction and risk management. The fund focuses on identifying businesses with durable competitive advantages across global markets and constructing a balanced portfolio of long and short positions. Cantillon has maintained consistently strong risk-adjusted performance, which has attracted a loyal institutional investor base that values predictability and discipline over extreme returns. The firm keeps a deliberately low profile.
