The rise of AI will usher in a new era in cybersecurity. Bots, deep fakes, targeted attacks and ransomware are merely the beginning. In this environment, we believe there is a tremendous opportunity for innovative technologists to build companies designed to counteract the next wave of cyber threats. Greylock eagerly wants to help initiate and advance these efforts up and down the cyber stack.
