The lesson
Build the sales deck in the buyer's world and lead with the proof that partners and artists already work with you.
The cover is a black, white and purple slide with the single music logo and "artist, label, & merchandiser tools for shopify". The deck then moves to partner logos and an artist roster, a data slide on merch share of stream revenue, one product screen per feature on black, and a fee comparison.
Don't copy the artist roster or the stream-revenue figure, which only fit this company. Keep the order: names, then a number, then product screens, then the price comparison.
