Microsoft to pay Inflection AI US$650 million after hiring most of staff, including founders

Microsoft stunned the AI world on Tuesday with an announcement that it had hired Inflection’s co-founders Mustafa Suleyman and Karen Simonyan, along with most of the start-up’s 70 employees. The unusual deal, first reported by Bloomberg News, resembled an “acqui-hire” – but without an acquisition. Some legal and industry experts have suggested that Microsoft’s Inflection deal might still spark antitrust concerns with US regulators, who are increasingly scrutinising Big Tech’s AI investments and partnerships.

Now, with a much smaller staff, Inflection is trying to offload some of its compute capacity, or access to computing power that can be used for tasks like training AI models, according to people familiar with the matter, who spoke on condition of anonymity to discuss private information. The company is seeking a partial refund from its cloud computing partner CoreWeave, one of the people said. The step could reduce costs related to building AI models as Inflection shifts to an enterprise rather than consumer business model.

As part of the deal, Microsoft will pay US$620 million to license Inflection’s AI models and around US$30 million for waiving any legal rights related to the mass hiring, according to one person. The financial terms were previously reported by The Information.

Microsoft and CoreWeave did not immediately respond to a request for comment. Inflection AI declined to comment.

The deal will make Inflection’s investors whole, as Bloomberg previously reported, with a modest return on investment. However, those investors aren’t immediately expected to reap big rewards on what once appeared to be an AI rocket ship, valued at US$4 billion after raising US$1.3 billion last year.
