TikTok is the world's best platform for music discovery and promotion, sparking meaningful dialogue, empowering creativity, and turning ideas into real-world impact across a global community of more than 1 billion users. The company empowers its community with tools to control and manage their presence on the platform and is passionate about earning the trust of its community through innovative features. TikTok's global headquarters are in Los Angeles and Singapore, with offices including New York, London, Dublin, Paris, Berlin, Dubai, Jakarta, Seoul, and Tokyo.
Recent partnerships include a multi-year strategic licensing agreement with Universal Music Group (UMG), offering the global community access to UMG's expansive recorded music and publishing catalogs while fostering deeper engagement between creators and UMG's artists. The agreement includes AI protections promoting human artistry, removing unauthorized AI-generated music, and improving artist and songwriter attribution. TikTok also hosts TikTok LIVE Premiere events (e.g., Paul McCartney Q&A for album 'The Boys of Dungeon Lane'), celebrates Small Business Month with Built on TikTok: Small Business Showcase, and supports small businesses through TikTok Shop (72% of newly discovered brands are small businesses; 89% of SMBs report increased sales after promoting on TikTok). Small businesses like Mississippi Candle Co., Club Coastal, Big Lee's BBQ, Angel Baked NYC, Yummy Tummy's Kitchen, The Bronx Native, and Pursuit by Brittany Ashley have grown significantly through TikTok.
