We are on a mission to improve the lives of marginalized workers across global supply chains, catalyzing economic justice.

The Problem

The supply chain holds enormous power in shaping the lives of people and the health of our planet. On average, a Fortune 500 company works with at least 10,000 suppliers and businesses. These vast and complex networks produce the clothes, food, electronics, and vehicles we rely on daily. This extensive global supply chain contributes to some of the most critical challenges facing humanity. Annually, it generates $354 billion worth of goods at risk of involving forced labor. Supply chains are also the primary source of greenhouse gas emissions, fueling the climate crisis and relying on the labor of over 17 million people in modern slavery conditions.

Fortunately, many emerging technologies can drive change at scale. Working Capital Fund invests in solutions like AI-enabled transparency tools that can map corporate supply chains and assess risk in real-time, worker-voice solutions that empower laborers to hold employers accountable, and financial technology ensures fair pay and generates sustainability data on upstream suppliers. These innovations can help create a more just and responsible global supply chain.
