**The Behavior Gap: Where Products Win or Lose** Teams today have more data than ever, and yet many still struggle to understand why customers adopt, engage with, or abandon their products. Teams sprint, ship faster, and chase more signals… all while metrics stall and confidence drops. The missing piece isn’t more data. It’s often the behavioral insight between the metrics, explaining why the numbers move in the first place. Dashboards can tell you what customers did, but understanding why they did it (and how to influence what they do next) requires a deeper blend of insights. This session is about closing that gap. Drawing from real-world experience designing and scaling products as [ZoCo Design](https://zocodesign.com/)’s CEO, [Lacey](https://www.linkedin.com/in/laceypicazo/) will share how to cut through the noise and identify the insights that actually change behavior—moving people, and moving metrics. You’ll learn: * Why understanding customer behavior is a quant and qual challenge * How to spot the signals that actually predict behavior change * Where AI accelerates insight, and where it creates distraction * How to get meaningfully closer to customers, without adding more tools This talk reframes how to evaluate performance and identify what levers actually improve it, helping your team to make smarter bets with greater confidence. Every meaningful outcome is driven by behavior change. And when you know how to design for behavior, you stop guessing, and start building things that work. **About Our Speaker** [Lacey Picazo](https://www.linkedin.com/in/laceypicazo/) is the Founder and CEO of ZoCo, a healthcare product studio that turns complex, high-stakes ideas into products that drive real-world adoption. She partners with healthcare organizations to uncover critical care delivery insights, focus product strategy through behavior design, and build solutions that patients and providers actually use.
