Mayank Agrawal co-founded Roundtable (YC S23) to tackle the growing challenge of distinguishing humans from AI online. As CEO, he leads development of Proof of Human technology that analyzes behavioral patterns (from typing dynamics to mouse movements) to create invisible, continuous verification. His PhD in Computational Cognitive Science from Princeton University provides the foundation for this approach, combining insights from human cognition with machine behavior analysis. His academic research, published in Science, PNAS, and Nature Human Behaviour, informs Roundtable’s mission to establish “humanness” as a fundamental building block of internet infrastructure.
