AI-native products require a new kind of collaboration, one that bridges the gap
between traditional machine learning (bottom-up, data-driven) and the way UX and
product teams typically operate (top-down, user-driven). Too often, these disciplines
speak different languages, leading to misalignment, slow iteration cycles, and missed
opportunities.
This panel will explore how product managers, UX designers, and developers can break
down silos to create AI products that are both technologically feasible and deeply user
centered. We’ll discuss how to integrate AI capabilities into the product development
process, establish shared frameworks for decision-making, and foster a culture of
experimentation.
Key Takeaway:
Whether you're building your first AI-native product or refining your approach, this
session will provide practical strategies to align teams and build better AI
experiences faster, together.

Launching a product feature powered by a model requires one essential step: A/B testingIn this session, we’ll detail exactly what you need on the experimentation side to make sure your model is performing better, ideally, then the control. The challenge in experimentation isn’t running the tests themselves, but rather the nuances and details key to designing a well-structured experiment, enabling you to gain the right insights to evolve your product and inform your larger AI strategy. Discussion points include:
- Understanding model behavior offline before starting the online evaluation phase
- Verifying experiments before launch through canaries or spot-check tooling
- Basic design principles that are fundamental to launching an A/B test on the product
- Simple strategies we implemented for Spotify’s Home page to increase the quality of experiments launched on the product
