In high-stakes film production, every crucial scene must be perfect. Directors can't risk their stars, expensive equipment, or production schedule on untested sequences. That's why they use stand-ins and stunt doubles — skilled professionals who rehearse complex scenes repeatedly, catching potential issues before the cameras roll and the stakes are highest.

Product development today faces a similar challenge. Teams must build software that performs flawlessly for human users while preparing for an emerging reality: the rise of AI agents as users. The stakes are just as high - every release risks your product's reputation, user trust, and business outcomes. Yet most teams are still working without their own version of a stunt double, trying to nail every sequence on the first take.

Today's Reality: Engineering for Human Diversity

Today's digital products must deliver exceptional experiences for human users across an ever-growing range of scenarios:

  • Complex authentication flows and user journeys

  • Diverse user behaviors and interaction patterns

  • Multiple devices, browsers, and platforms

  • International audiences with different needs and expectations

  • Critical business workflows that must work flawlessly

Traditional testing methods strain under these demands. Manual testing is too slow, automated tests are brittle, and real user testing is expensive and time-consuming. The result? Teams ship with uncertainty, discover issues in production, and struggle to validate changes across all user scenarios.

The Plot Twist: AI Enters the Scene

While teams grapple with these challenges, product development is experiencing its most dramatic transformation since the mobile revolution. A new type of user is emerging - AI agents that act as both independent users and intermediaries for human users. These aren't simple chatbots or basic automation tools. Today's AI agents are sophisticated performers that can:

  • Navigate complex interfaces autonomously

  • Process and interpret diverse content types

  • Execute intricate sequences of actions

  • Learn and adapt their behavior based on context

  • Make nuanced decisions using multiple inputs

This is why we built Stunt Double.
