Overview
Declaration Partners is a New York investment firm founded in 2017 and anchored by the family office of Carlyle co-founder David Rubenstein — family capital run by people who spent careers inside institutional private markets. It invests flexibly across growth equity, private equity and real estate, unconstrained by fund cycles, and partners with other family offices and entrepreneurs on deals. For GPs, Declaration represents sophisticated family capital that understands fund mechanics natively and can move decisively on both direct opportunities and manager relationships.
