@elbahnasy there's a lot of platforms out there catering to musicians, bands, or DJs, which is great if that's all you're looking for. We've found through organising live events, often we'll need multiple disciplines within the entertainment sector (a band, emcee, event photographer, caterer etc) and having one place to find and book everyone at the same time seems like a no brainer to us :)
