Jonathan Manderson

Jonathan Manderson is Managing Partner of GSTJ LLC, working across the firm’s origination and transaction execution. He is named as an originator under the firm’s transaction-execution procedures and is responsible for sourcing opportunities and carrying them from first contact through close. That work begins before a transaction has a final structure. It requires a clear understanding of the parties, the asset or project being evaluated, the decision process, the information still needed, and the practical steps required to convert interest into an executable process.

Manderson’s mandate connects institutional relationships with disciplined follow-through. In turbine and energy-asset transactions, an introduction is only the beginning: ownership, equipment status, commercial authority, technical records, delivery rights, counterparties, timing, and closing requirements all have to be made explicit. He works across those stages so that the commercial narrative remains tied to the transaction record and the parties understand what must happen next. The same approach applies whether the subject is an equipment position, a broader power asset, or an infrastructure relationship that may develop through multiple stages.

He works alongside Eileen Murray, former co-Chief Executive Officer of Bridgewater Associates and former chair of the FINRA board. Within the scope of GSTJ’s supplied leadership information, that relationship reflects the institutional context surrounding Manderson’s origination work. His role at GSTJ remains focused: build credible relationships, identify opportunities that fit the firm’s operating sectors, maintain continuity from initial discussion through diligence, and support execution through close. The emphasis is not on volume of introductions, but on the quality of the opportunity, the clarity of the process, and the ability of all parties to carry their responsibilities to completion.
