Spotify was founded in 2006 by Daniel Ek and Martin Lorentzon to make music available to everyone legally through a streaming service. It has since grown to have over 24 million active users who listen for many hours each day. Spotify offers both an ad-supported free tier and a paid premium subscription. Spotify Ads works with brands to connect with Spotify's large user base through various advertising options like audio, display, and branded playlists.
