Cloud infrastructure provider Lambda announced it has secured more than $1.5 billion in a Series E funding round led by TWG Global, with participation from US Innovative Technology Fund (USIT) and several existing investors.
The company said the investment will fast-track its plans to build “gigawatt-scale AI factories” and large-scale supercomputing infrastructure aimed at hyperscalers, enterprises and advanced AI research labs. Lambda delivers large-scale compute factories for both training and inference at a time when data-center space is constrained and demand for AI hardware is accelerating.
The firm noted that it serves tens of thousands of customers, from AI researchers to major enterprises and hyperscalers, leveraging its founding team’s machine-learning pedigree and infrastructure engineering expertise.
From TWG Global’s side, co-chairman Thomas Tull said the firm has been “consistently impressed” by Lambda’s team and its infrastructure delivery at unprecedented scale, calling compute for AI “a defining infrastructure challenge of our time.” Meanwhile, USIT managing director Gaetano Crupi described Lambda as positioned to address the “energy-to-cognition pipeline” in the era of large-scale AI.
The funding will support Lambda’s strategy to deploy multi-gigawatt capacity, build out AI infrastructure factories and accelerate its mission to democratize supercomputing for AI.
KEY QUOTES:
“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.”
“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 realise this vision.”
Stephen Balaban, Co-Founder & CEO, Lambda
“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.”
“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.”
Thomas Tull, Co-Chairman, TWG Global & Chairman, USIT
“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.”
“We are excited to continue supporting Lambda as it becomes a key player in the industrialisation of inference and helps the U.S. master the energy-to-cognition pipeline.”
Gaetano Crupi, Managing Director, USIT
