Why it mattered

Inflection had raised $1.5bn, including from Microsoft, to build a consumer chatbot called Pi on its own models, and had found, like every lab outside the top three, that the cost of the next model exceeded what its product could earn. Microsoft wanted Suleyman, a DeepMind co-founder, to run its consumer AI, and wanted the team; it did not want the company, the product or the regulatory review that buying a $4bn start-up would bring. So it licensed the models for enough money to repay Inflection's investors and hired the people, and Inflection continued as a much smaller enterprise-software company.

The structure was new, and it was immediately copied: Amazon with Adept in June 2024, Google with Character.AI in August, Meta with Scale AI in 2025. The FTC opened an inquiry into whether it was an acquisition by another name; the UK's CMA reviewed it as a merger and cleared it.

What it left behind

A category — the "acqui-hire licence" — and a question regulators are still answering. It also marked the point at which the second tier of foundation-model labs stopped being acquisition targets and became talent pools: the models were licensed for a fraction of what the companies had raised, and the people were what the buyers paid for.
