We pioneered a new way of investing over 20 years ago and we’re still at it. Your gift allows us to invest capital where it is needed most, taking outsized risk for outsized impact.

“In this time of crises and contestation, the Acuverse, as I sometimes like to call it, is a place where my optimism has gone to live… In it I see deeper truths about our interconnectedness and what we can achieve if we are just a bit kinder with one another…”

– Andrea Soros Colombel, Board Member, Acumen and Open Society Foundations
