Block operates a portfolio of financial services including Square (merchant payments), Cash App (consumer finance), TIDAL (music streaming), and Spiral (Bitcoin development).
Block has integrated AI across its product ecosystem, with a particular focus on AI-powered financial services for small businesses and consumers.
