WitnessAI has secured fresh capital of $58m as it looks to accelerate global expansion and broaden its product offering in response to growing demand for secure AI adoption across regulated industries.

The company has raised $58m in strategic funding in a round led by Sound Ventures, with participation from Fin Capital, Qualcomm Ventures, Samsung Ventures and Forgepoint Capital Partners. Sound Ventures is known as an early investor in companies such as OpenAI, Anthropic and SentinelOne, while the broader investor group brings experience spanning financial services, semiconductors, consumer technology and cybersecurity.

Founded to address the security and governance gaps emerging from rapid enterprise AI adoption, WitnessAI positions itself as a confidence layer for organisations deploying large language models and AI-powered applications. Its platform is designed to give enterprises visibility and control over how AI systems are accessed, what data they interact with and how decisions are made, particularly as AI agents become embedded into everyday workflows.

WitnessAI said the new funding will be used to accelerate its global go-to-market strategy and expand its product capabilities. A key focus will be supporting organisations that are developing and deploying agentic AI systems, which act autonomously on behalf of users and interact with multiple tools, models and data sources. The company is also investing in scaling its operations to meet growing demand from large enterprises operating across multiple regions.

Alongside the funding announcement, WitnessAI unveiled expanded agentic AI governance capabilities aimed at improving observability across both human and AI workforces. The platform can monitor which agents are active, which tools and servers they are accessing and what data they are sharing, while connecting human and agentic identities to provide explainability around AI-driven actions. It also extends application protection from AI models to agents, blocking malicious prompts and advanced attacks such as prompt injection before they reach execution.

The company said its approach enables policy enforcement based on behavioural intent, allowing enterprises to understand the meaning behind prompts rather than relying solely on static rules. WitnessAI Agentic Security is scheduled to be available from January 2026.

WitnessAI said it is already protecting hundreds of thousands of enterprise employees and applications. Over the past 12 months, the company reported more than 500% growth in annual recurring revenue and a fivefold increase in headcount. Its production customers include large publicly listed enterprises across financial services, utilities, automotive, aviation, retail and telecommunications.

Sound Ventures general partner Ashton Kutcher said, “The primary barrier to enterprise AI adoption isn’t tech debt; it’s tech doubt. WitnessAI has proven it can instill confidence in AI adoption, and has done so for multiple global leaders. We are thrilled to support the team as they use this capital to expand into new markets and solidify their position as the leading standard for safe, secure enterprise AI.”

Qualcomm Technologies vice president and managing director of Qualcomm Ventures North America Tushar Gupta said, “The future of AI is hybrid, spanning both cloud and edge. Qualcomm is delivering AI-first experiences across a multitude of devices, where privacy and security are paramount. WitnessAI has developed a platform that governs and protects AI agents, models, applications, and users—wherever they operate. We’re excited to invest in WitnessAI as they build the essential infrastructure for the agentic era.”

Fin Capital managing partner Logan Allin said, “Financial Services often leads the way in new technology adoption, and AI is no exception. We believe that WitnessAI is poised to be the category leader in secure AI adoption for financial services institutions of all sizes across banks, asset and wealth managers, and insurers, all of whom are crossing the chasm and must do so with a robust bridge.”

WitnessAI co-founder and CEO Rick Caccia said, “AI workflows are maturing and starting to cross corporate and cloud LLMs and agents. We are the only AI security vendor that can secure every AI interaction, everywhere, with a unified solution. The alternative is trying to stitch together secure workflows using network proxies, firewalls, DLP products, and XDR agents. In short, the alternative is a complex mess.”
