"Adaface's success relies on creating seamless, high-stakes candidate interactions. UserTrace allowed us to simulate diverse candidate journeys with our interview bots, revealing where conversations broke down. That feedback directly shaped improvements and led to higher candidate satisfaction."

Deepti Chopra

"Virtual Internship connects students worldwide with real companies, and every interaction matters. UserTrace simulations helped us stress-test our onboarding AI across different student personas, uncovering friction points we would have missed with manual testing. Fixing them upfront dramatically improved conversion rates."
