WitnessAI is the confidence layer for enterprise AI — a unified security and governance platform purpose-built to help organizations adopt AI safely and at scale. Backed by GV (Google Ventures) in a $27M Series A and a recent $58M strategic round led by Ashton Kutcher's Sound Ventures, WitnessAI is one of the fastest-growing companies in the AI security space.
The platform provides complete visibility into employee AI usage, secures internal and customer-facing AI applications against prompt injection and data leakage, and extends intent-based governance to agentic AI systems — all deployable at the network level in days with no agents or plugins required.
Unlike legacy tools that rely on keyword blocking, WitnessAI uses ML-driven intent classification to understand why AI is being used, enabling smart controls that protect the business without slowing people down. Trusted by global enterprises including Delta Airlines, Charles Schwab, Toyota, NTT, and InterContinental Hotels, WitnessAI is already running in production — at scale — across some of the world's most security-conscious organizations.
