WitnessAI announced it has raised $58 million in strategic funding to accelerate global go-to-market efforts, expand its product portfolio, and deepen security and governance controls for enterprises building and deploying AI agents.
The round was led by Sound Ventures and included participation from Fin Capital, Qualcomm Ventures, Samsung Ventures, and Forgepoint Capital Partners, according to the company. WitnessAI positioned the financing as fuel for international expansion and continued development of what it describes as a unified “confidence layer” for enterprise AI adoption.
Alongside the funding announcement, WitnessAI introduced expanded agentic AI governance capabilities intended to provide observability into how AI agents operate inside organizations. The company said its platform can monitor which agents are active, what MCP servers and tools they access, and what data they share, with the goal of helping security teams understand actions taken on behalf of employees or customers.
WitnessAI said it is also extending AI application protection beyond models to agents by blocking attacks and malicious prompts before they reach an agent. The company said its policy engine evaluates behavioral intent rather than relying on keyword-based rules, aiming to better detect threats such as prompt injection and multi-turn attacks.
WitnessAI said its “Agentic Security” capabilities are available in January 2026. It also highlighted business momentum over the last year, citing more than 500% growth in annual recurring revenue and a fivefold increase in headcount.
The company said it is already deployed in production across large publicly held enterprises in sectors including financial services, utilities, automakers, airlines, retail, and telecommunications. WitnessAI previously raised $27.5 million in a Series A round in May 2024, co-led by Google Ventures and Ballistic Ventures.
