WitnessAI Raises $27.5M in Series A Funding


WitnessAI, a San Mateo, CA-based creator of an enablement platform for safe AI use, raised $27.5M in Series A funding.

The round was led by GV and Ballistic Ventures.

The company intends to use the funds to accelerate development of new AI guardrails and build out a global sales and support organization.

Led by CEO Rick Caccia, WitnessAI is deployed as an isolated, cloud-based instance for each customer, encrypted with their own keys to ensure data privacy and regulatory separation. The platform intercepts activity between users and LLMs, applies control policies, and ensures data protection and user safety – all with millisecond latency and requiring nothing to be installed on the users’ devices. Achieving this requires an integrated design that blends new techniques in machine learning, offensive and defense security for AI activity, and enterprise-scale web services deployment.

Commenting on the news, Rick Caccia said: “We’ve built something that works in the most demanding environments, including global organizations and across clouds. The response from CISOs we’ve spoken with has been tremendous.”

The company had previously been incubated by Ballistic Ventures, beginning in 2023.
