This document discusses the challenges of sustaining disruptive innovation after a startup achieves success. It notes that it can be harder to innovate within a successful startup due to competing demands on resources and pressure to maintain existing revenue streams. The document outlines three steps the author took to continue disruptive innovation at their startup: 1) Create the right environment by isolating resources and not overpromising changes, 2) Set goals and boundaries through customer development and building minimal viable products, and 3) Use milestones and progress checks separate from existing workflows to regularly assess assumptions and iterate differently than before.
