S2G Ventures operates as the direct investment arm of Lukas Walton's impact platform Builders Vision, giving it a single-family ownership structure that allows it to pursue long-term systems change in food, agriculture, oceans, and energy rather than answering to traditional limited partners. The firm positions itself "at the seams of sector transition" by focusing on overlooked intersections across these sectors and runs a multi-stage strategy that blends venture, growth equity, and real assets to back entire value chains rather than operating as a pure venture fund.
