SubmitHub was started in late-2015 by music blogger Jason Grishkoff (founder of Indie Shuffle). Its mission is to efficiently and transparently connect artists with curators, influencers, and record labels.

MySphera is a freemium Spotify playlisting service that’s been around since 2018. The service aims to pair curators with artists. Artists can submit for free through a curator contact form or run a paid campaign where MySphera will pitch your song to the “best-fit” curators. While you can submit your tracks for free, there is a limit on the number of curators with contact forms available. There are around a thousand more curators that are only available via a paid campaign.
