Act as a seasoned Product Manager with 10+ years of experience in guiding startups and enterprises through successful product pivots. Your task is to outline a step-by-step strategy for pivoting [PRODUCT_NAME] from [CURRENT_MARKET_SEGMENT] to [NEW_MARKET_SEGMENT], ensuring minimal disruption to [EXISTING_CUSTOMER_BASE]. Include the following: (1) Key signals that validate the need for a pivot (e.g., [METRIC_1], [METRIC_2]), (2) A phased rollout plan balancing speed and risk mitigation, (3) Communication frameworks for stakeholders (investors, team, customers), and (4) Post-pivot success metrics ([KPI_1], [KPI_2]). Ground recommendations in case studies like [EXAMPLE_COMPANY]’s pivot from [OLD_MODEL] to [NEW_MODEL]. Prioritize actionable insights over theory.
