Cloud computing company Lambda said it has raised over $1.5 billion in its Series E funding round led by TWG Global.
US Innovative Technology Fund (USIT) and several existing investors also participated in the funding round, said Lambda in a statement.
“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.
Lambda, which was founded by twin brothers Michael and Stephen Balaban in 2012, started as an AI photo editing app. But gradually they started building their own cluster of graphic processing units (GPUs) to sell to other companies.
This funding round comes just months after Lambda raised $480 million in its Series D investment round earlier in February co-led by Andra Capital and SGW
Earlier this month, Lambda said that it has signed a multibillion dollar agreement with Microsoft.
