Capricorn Investment Group is an unusual organisation. Born from the private wealth of billionaire and former eBay president Jeff Skoll, it now operates a number of different sustainability-oriented strategies from its bases in New York and Palo Alto, and acts as an outsourced chief investment officer for other foundations and endowments alongside the Skoll Foundation. Among its strategies is the Sustainable Investors Fund, a programme which seeks to add scale to the sustainable investment universe through GP stakes investment. In February, the strategy backed Closed Loop Partners, a leading firm in the field of circular economy investing (and also a winner in the latest New Private Markets Global Awards). In this episode of The New Private Markets Podcast, recorded at PEI Group's NEXUS 2025 event in Orlando, we speak to Marie-Céline Damnon, investment director at Capricorn Investment Group, to discuss the strategy, the Closed Loop Partners deal and the landscape for investing in sustainable asset managers at a time when the concept of sustainability – in the US anyway – is not flavour of the month.
