Daniel Gross went from a member of X-energy’s board to its CFO after four years at Amazon’s Climate Pledge Fund.
Daniel Gross joined US-based nuclear reactor technology developer X-energy as chief financial officer, closing the chapter on his time at Amazon’s Climate Pledge Fund.
After over four years as corporate development director at Amazon’s Climate Pledge Fund, Gross, who served on X-energy’s board, is taking over as the startup’s finance chief just weeks after it raised a Jane Street-led $700m series D round that included XTX Markets’ startup investment unit, XTX Ventures.
“Through my role at Amazon’s Climate Pledge Fund and as a board member of X-energy, I’ve had a front row seat to the company’s vision, technology, team, and potential. One thing is abundantly clear: X-energy is the real deal,” said Gross on LinkedIn.
The Climate Pledge Fund invested as part of X-energy’s C1 round, which was announced in October last year, before closing at $700m in February 2025.
Before Amazon, Gross spent a year as chief investment officer at Climate Real Impact Solutions, having previously cofounded project finance training and advisory firm Pivotal180 and invested in the energy sector from firms including Oaktree, Hudson Clean Energy, Goldman Sachs and GE Capital.
