SymphonyOS

Symphony is a marketing workspace built specifically for the label teams, managers and marketers behind recording artists. It pulls the routine work of a release cycle — flighting ad campaigns, tracking a catalogue, drafting fan sends and writing artist updates — into one place, with your team making every decision. The tool was previously known as SymphonyOS; the /join page has since been retired as the product matured and rebranded to Symphony.

The platform pairs conventional tooling with seven named AI agents. Maestro keeps each artist's plan and context together, Simmy builds ads across Meta, TikTok and YouTube, Cue runs the release checklist and sets up link-in-bio pages, pre-saves and forever-saves, Echo maps fan lists and drafts messages, Maude reads catalogue and royalty data, Sage finds creators already posting to a record, and Momo reads socials for what landed. Each agent shows its work and hands the decision back.

Control is the distinguishing feature. New campaigns launch paused until approved, creator batches wait for a person to release them, and every fan email or text is held for sign-off in the CRM. Ad accounts stay in your name via the official Meta and TikTok APIs, media spend is billed by the platforms directly, and an activity log records audiences built, spend paced and messages sent. Pricing is per artist: Pro at $49/month for ads, pages and fan messaging, and Advanced at $250/month for labels and managers who need Catalog, Socials and Creator campaigns across the whole roster.
