At Exabeam, Daniel Castro led the product design and user experience strategy during a pivotal phase of growth in the cybersecurity space.

By aligning design with real-world user needs—from security analysts to CISOs—he helped ensure that the product solved the right problems, for the right people. His ability to align cross-functional teams across the entire customer journey—spanning Product, Engineering, Sales, and Customer Success—was a catalyst in transforming UX from a support function into a strategic growth driver.
