Microsoft has hired Mustafa Suleyman and Karén Simonyan, co-founders of high-profile AI startup Inflection AI, and several of their colleagues as the Satya Nadella-led cloud giant continues its aggressive push to attract top talent.

Suleyman — also a co-founder of DeepMind, which Google bought in 2014 to bolster its own AI efforts — will run Microsoft’s newly formed consumer AI unit, called Microsoft AI, whereas Simonyan is joining the company as a chief scientist in the same new group. Mustafa, whose official title at Microsoft is EVP and CEO of Microsoft AI, will report to chief executive Nadella.
