Zimmer Partners LP

Jonathan M. Zimmer is the founding managing partner and controls final investment decisions. He previously worked at Goldman Sachs and Fortress Investment Group. Partners John L. Auerbach and James M. E. G. Zimmer also play key roles in sourcing and executing deals.

Zimmer Partners targets control or influential positions in cash-flowing assets with hard-asset backing and long-duration revenue. This includes direct investments in operating infrastructure, asset-based private credit, and energy transition projects, rather than venture-stage or growth equity.

The firm focuses on infrastructure, private credit, energy transition and renewables, real estate, and special situations. It does not appear to focus on traditional liquid markets, venture capital, or technology startups.

Zimmer Partners has historically co-invested with large institutional capital providers in infrastructure and credit deals, acting as an operating or structuring partner rather than a passive LP.
