Ex-Argo MD Aaron Gold joins CAI as president (Infrastructure Investor Exclusive)

In this newly-created role, Gold will be based in New York, helping the firm expand its footprint to the East Coast and leading CAI’s next phase of growth alongside its founder Bill Green.

Climate Adaptive Infrastructure has appointed Aaron Gold as partner and president of the California-based investment firm specialising in low-carbon real assets, “a new role, which we have been working towards as a team for over 18 months”, CAI founder and managing partner Bill Green told Infrastructure Investor.

“The current team determined that, as we grow, we would need more experienced hands around the table,” Green added.

Gold brings more than 25 years of experience in infrastructure investing, beginning with Highstar Capital (now part of Oaktree Capital Management), which he joined in July 2001 as managing director. In 2011 he became a principal at Carlyle Infrastructure Partners, a position he left in 2013 to become a founding member and managing director of Argo Infrastructure

Partners, a mid-market investment firm where he spent a little over 11 years. As of February 2025, Gold is CFO at Engine No. 1, an investment firm focusing on the reindustrialisation of the US, according to its website.

In his new role at CAI, he will focus on “investment strategy, transaction origination and execution, portfolio management and capital formation”, the firm said in a statement seen by Infrastructure Investor.

Green acknowledged that that is a broad remit, “but we all do multiple things here at CAI, being a team of 18 people”, he commented. “Aaron will initially manage the day-to-day operations of the firm, freeing me up to focus on the current capital formation efforts and will participate in the investment process, bringing his decades of pattern recognition to the discussions with other team members.”

Gold’s official start date is Monday, 20 April, and he will be based in New York. This will mean that CAI will now have senior partners on both the East and West Coast, “expanding our footprint in a critical hub for capital formation and strategic partnerships”, according to the statement.

He will report to and collaborate with Green “to lead the firm’s next phase of growth”, CAI said in the statement.
