Series E funding, led by TWG Global with participation from US Innovative Technology Fund (USIT) and several existing investors.

“This round of funding helps enable Lambda to develop gigawatt-scale AI factories that power services used by hundreds of millions of people every day,” said Stephen Balaban, co-founder and CEO of Lambda. “Our mission is to make compute as ubiquitous as electricity and bring the power of AI to every person in America. One person, one GPU. It’s a privilege to work with Thomas, USIT, and TWG Global to realize this vision.”

Lambda delivers large-scale AI factories that power mission-critical training and inference, just as demand for compute is rising and data center space is scarce.

“Since meeting Stephen and the Lambda team several years ago, we have been consistently impressed by their visionary focus and ability to deliver infrastructure at unprecedented scale,” said Thomas Tull, Co-Chairman of TWG Global and Chairman of USIT. “Generating enough compute power for AI is a defining infrastructure challenge of our time. We believe that Lambda is well-positioned to solve this challenge and continue to deliver in the decades ahead.”

The company’s AI specialization stems from its published machine learning founders, as well as its pioneering work in cloud supercomputers.

“As we move into a new phase of AI scale, the most valuable infrastructure will be that which converts kilowatts into tokens with minimal friction,” said Gaetano Crupi, Managing Director at USIT. “We are excited to continue supporting Lambda as it becomes a key player in the industrialization of inference and helps the U.S. master the energy-to-cognition pipeline.”
