A power user is a customer who uses a company's software more often and in more effective ways than other users, typically identifying them with usage and engagement metrics. These customers are highly engaged segments of monthly active users, providing valuable feedback that influences product development and can become product advocates or ambassadors. The qualities of a power user include being repeat users, open to sharing regular feedback, early adopters of new features, and often discovering new ways of using the product. Power users bring value to businesses through multiple avenues, including offering a continuous revenue stream, acting as organic advocates, providing actionable feedback, and contributing to the product roadmap. Software companies should aim to foster their communities of power users and tap into their potential to maximize the benefits.
