Closed Loop Partners operates as a full circular economy platform that combines venture capital, private equity, project finance, and an in-house collaboration lab, using different pools of capital to back the same companies as they move from R&D to commercial scale while also purpose-building physical recycling infrastructure projects in North America. The firm's LP base is dominated by incumbent consumer, retail, and industrial corporates who serve as both capital providers and demand-side partners, using Closed Loop Partners as an outsourced R&D and deal flow engine for their circular supply chains.
