Block

Block builds technology for economic empowerment. Its portfolio of products includes Square (commerce tools for businesses), Cash App (peer-to-peer payments and financial services), Afterpay (buy now, pay later), TIDAL (music streaming), Bitkey (self-custody bitcoin wallet), and Proto (hardware for emerging markets).
