What Engine No.1 LLC does

Engine No. 1 LLC is a privately held San Francisco-based holding company and SEC-registered investment adviser founded in 2020 by Christopher James. It originated as an activist investment firm, gaining prominence in 2021 by campaigning to elect three independent directors to ExxonMobil's board and realizing a 350% return on its 2020 ExxonMobil position when it exited in 2024. The company has since pivoted from pure financial investing toward building and operating energy infrastructure intended to power the reindustrialization of the United States, with a particular focus on supplying multi-gigawatt baseload power to AI and hyperscale data center operators.

The firm's core operating product is Joulent, a wholly-owned subsidiary launched in June 2026 that delivers multi-gigawatt power generation under its trademarked Across-the-Meter™ model, which co-locates generation, storage, and advanced controls behind the customer meter. The technology stack is anchored by GE Vernova's 7HA gas turbines, with Chevron providing fuel supply and capital through a partnership announced in January 2025 that targets 4GW+ of initial capacity. Joulent's anchor project, Project Kilby in West Texas, is contracted to deliver approximately 2.67 GW under a 20-year power purchase agreement to a Microsoft-operated data center. The firm has also formed a March 2025 joint venture with Crusoe to develop powered AI data centers, and operates through two legal entities — Engine No. 1 LP and Engine No. 1 GP LLC.

Engine No. 1's revenue model is a hybrid: traditional investment-management/fund returns from its financial-investing activities, and (going forward) long-duration recurring revenue from multi-gigawatt power purchase agreements through Joulent. The go-to-market is enterprise-direct, targeting hyperscale AI and cloud computing operators as its primary customer segment, with energy companies as a secondary partner segment. Current operations are concentrated exclusively in the United States.
