Investment thesis
Mastersfund invests non-dilutive capital of $50K-$100K into seed-stage, women-led technology companies that already generate sales, structuring deals as convertible notes with revenue-based repayment. It requires at least one woman in a position of strategic and operational control who is appropriately titled and equitably compensated, and takes a board seat on every portfolio company. The firm argues that conventional venture capital over-invests in all-male teams, and that revenue-based funding gives investors recurring returns within three to five years while letting founders retain more equity. It emphasizes clean cap tables and sustainable, profitable business building as a path to earlier, steadier returns and higher-ROI exits.
