Closed Loop Partners Research

Investment Thesis

The firm invests across R&D through commercial scale, uniquely combining VC, private equity, and project finance with a collaboration lab and corporate demand partners while building North American recycling infrastructure.

The firm's core belief is that the circular economy—where products are designed, manufactured, sold, refurbished, and recycled in closed loops—represents both a resilient economic system and significant investment opportunity. They prioritize natural resource efficiency, optimize supply chains, and drive measurable environmental and economic value.
