Investment thesis

Mastersfund is a global gender-lens investment fund chartered to source, fund, and champion diverse founding teams that include at least one woman in a position of strategic and operational control. Named after 18th-century inventor Sybilla Masters, the fund is built on the belief that both men and women benefit when everyone is equally supported and rewarded in building new products and processes. It emphasizes that women and people of diverse backgrounds have historically been excluded from invention, business ownership, and the rewards of their own work, and aims to correct that imbalance by backing early-stage founders and connecting them with experienced entrepreneur-investors.
