The music executive stole the show at its annual developer conference on Monday.

If you watched the livestream of Apple’s annual developer conference on Monday, you would have seen there was one Apple executive who out shined her fellow colleagues while presenting on stage: Bozoma Saint John.

One of the few female executives on stage, Saint John is Apple’s head of global consumer marketing for Apple Music. She shared news about Apple’s streaming music service, which has accumulated 15 million users, according to the company.

It’s no surprise that Apple appointed Saint John as the head of marketing around one of its highest profile services, Music, as she has built an impressive career around connecting musicians and artists with brands.
