Zimmer Partners LP

Zimmer Partners LP

Zimmer Partners LP was founded by Jonathan M. Zimmer, who previously held senior roles at Goldman Sachs and Fortress Investment Group. The firm operates as a private investment partnership focused on special situations, credit and infrastructure assets — a structural niche that demands both deep capital markets expertise and operational patience. The strategy spans asset-based private credit, infrastructure equity, energy transition assets and real estate. Zimmer Partners targets control or influential positions in cash-flowing assets with hard-asset backing and long-duration revenue streams. Confirmed public reference includes co-investment partnerships with major institutional capital providers in infrastructure debt and renewable-energy projects. The firm's geographic footprint covers North America and Japan, with the Tokyo office indicating a specific focus on Asian infrastructure opportunities, particularly in energy transition. The firm's total deployment and internal professionals count are not publicly disclosed. Additional offices include Short Hills, New Jersey, complementing the main New York headquarters. No publicly listed philanthropic foundation or adjacent vehicles are associated with the firm. The most recent verifiable public event is a 2023 SEC filing showing the firm's continued registration as an investment adviser, signaling ongoing operational activity rather than wind-down. Zimmer Partners' structural differentiator is its explicit positioning as a special-situations investor that works across asset classes rather than within a single vertical. This allows the firm to pivot across credit, infrastructure and real estate as relative value shifts, and to co-invest with institutional limited partners who need a nimble operator for complex, non-auctioned deals — a model that more closely resembles a family-office investment office than a standard asset manager.
