XConf Europe 2025 - Madrid

About this event

What is XConf:

XConf is a tech conference created by technologists, for technologists who care deeply about the craft of software and its ability to make the world a better place. With its relaxed atmosphere and focus on high-quality topics and talks this one-day, two-track event offers a unique opportunity to connect with like-minded technologists. It’s a space to explore bold ideas, challenge yourself with fresh perspectives and deepen your understanding of the role technology plays in solving real-world problems. Like catching up with old friends at a class reunion, XConf combines familiarity and inspiration in a way that leaves a lasting impact.

Why you should attend:

• Actionable insights grounded in expertise: XConf is built on Thoughtworks’ and our clients’ years of experience tackling complex problems across industries and markets, so you’ll leave with practical takeaways you can use right away.
  
• Deep technical knowledge: For over 30 years, Thoughtworks has been at the forefront of technological innovation, introducing groundbreaking practices like continuous delivery and infrastructure as code. XConf brings together the technologists who’ve shaped these innovations to share what works and what doesn’t.
  
• A diverse lineup: XConf celebrates diversity with the target of a 50/50 gender split among our speakers. This ensures a balance of perspectives and insights from a broad range of backgrounds and experiences.

Exclusive keynote by Holly Cummins:

Things you thought you didn’t need to care about that have a big impact on your job

Development is about working with computers, right? Well, not quite. Development is all about working with computers (easy), and working with people (hard). Oh, and it’s about physics.

Things like the speed of light and thermodynamics influence APIs, because they influence hardware and networking. If, like Holly, you slept through statistics modules in university, it will be a surprise to discover how statistics has changed our development workflows. Finally, we mustn’t forget economics. The end of zero-interest-rates has changed the employment landscape for many of us. In this wide-ranging talk, Holly will cover why the end of Moore’s law means we might finally need to get to grips with concurrent programming, why is Loom a good idea now when green threads were a bad idea, why is AOT a good idea now when it used to be a bad idea, and how much you should care about business studies, finance, and statistics.
