The Future of Product Design: Disrupting UX with Synthetic Users with Borja Díaz-Roig

Join Borja Díaz-Roig, Co-founder and CEO of Uxia, for a provocative look at how AI is rewriting the rules of product development. As a product leader with experience at Google, Gopuff, and TransferGo, Borja is now at the forefront of the "synthetic research" revolution. In this episode, we explore how Uxia is enabling design teams to bypass traditional, slow recruiting by using AI-generated testers to validate UX instantly. Discover why user testing is more critical than ever in 2026 and how the roles of designers and researchers are evolving in an AI-native world.🎯 Insights You’ll Learn:✓ What are Synthetic Testers? How AI-generated users are disrupting traditional UX research✓ The Speed of Experimentation: Validating designs in minutes instead of weeks✓ Why User Testing is non-negotiable in the age of hyper-competition✓ How platforms like Uxia are changing the daily roles of designers and researchers✓ Moving beyond the "Human-Only" bottleneck: When to use AI vs. real human participants✓ Lessons from Barcelona’s tech scene: Building an AI-native startup for global scale✓ The Future of UX: Predicting how research will evolve over the next 24 months🌍 Why This Matters:In the race to build the perfect digital product, the biggest bottleneck has always been human feedback—finding, scheduling, and interviewing users takes time that modern sprints don't have. Borja Díaz-Roig is solving this "velocity gap." By leveraging AI to simulate diverse user personas and behaviors, Uxia allows teams to iterate daily, ensuring that when they finally do ship to real humans, the product is already highly optimized. This isn't just a new tool; it's a fundamental shift in how we understand user needs.👤 Expert Background:• Co-founder & CEO of Uxia, an AI-native research platform for synthetic user testing• Former Product & Growth leader at TransferGo, Gopuff, and Google• Expert in high-velocity experimentation and digital product strategy• Based in Barcelona’s thriving tech hub with a focus on AI/UX intersection• Thought leader on the digital transformation of the user research industry🎙️ Hosted by Gary Fowler, CEO of GSD Venture Studios — global AI entrepreneur, investor, and innovation leader spotlighting founders navigating the realities of building in the AI era.💡 Perfect For:Product Designers, UX Researchers, Product Managers, Growth Hackers, and AI Founders looking to accelerate their validation cycles and build better products faster.🚀 Timely Topic:As AI makes it easier to build software, the "UX Moat" becomes the primary differentiator.
