Infrastructure Layer for the Music Industry
€550K raised, paying customers

A professional musician had an idea for a startup addressing $2.5 billion in unclaimed royalties. Split sheets are missing, metadata is incomplete, and accreditation goes undocumented. Any one of these gaps can cost musicians money. Usually all three are broken at the same time.
No single source of truth for music projects. People use WhatsApp, Dropbox, Google Drive, and WeTransfer but none handle metadata, which is essential for getting paid. Most people in the industry don't want to deal with metadata because the tools make it tedious.
