  • 2014Risk

    The Founding Stage Lawsuit

  • 2021Brand

    Rebranding to Block

    Shortly after Dorsey resigned as CEO of Twitter, Square changed its name to Block, Inc. to reflect its expanding ecosystem beyond just payment processing. This move coincided with acquisitions like Tidal and Afterpay.

    LessonA name change can signal a shift in company scope when the original brand no longer encompasses all business activities.

  • Regret Over Centralized Control

    Reflecting on his tenure, Dorsey admitted that his biggest mistake was building internal tools to manage public conversation. He believed he should have built tools for users to manage their own experiences.

    LessonEmpowering users with self-management tools is often better than building centralized moderation systems.
