NeuralTrust Raises $20M Seed for AI Agent Cybersecurity

NeuralTrust, a cybersecurity innovator focused on safeguarding artificial intelligence agents, has successfully closed a $20 million seed funding round. This significant capital infusion, reportedly the largest seed round for an EU-based cybersecurity firm to date, was spearheaded by Alstin Capital. The investment underscores the escalating demand for robust AI governance solutions as businesses increasingly deploy autonomous AI systems.

The funding will fuel critical growth initiatives for NeuralTrust, including expanding its engineering talent pool, deepening product integrations, and accelerating its market penetration across Europe. This expansion is particularly timely, as organizations are transitioning AI agents from experimental phases to core operational infrastructure, often outpacing their ability to implement effective governance frameworks. Industry projections from Gartner suggest that by 2027, a substantial 40% of enterprises may retract autonomous AI agents due to governance failures discovered post-deployment incidents.

The investor syndicate backing NeuralTrust is robust, featuring prominent venture capital firms such as VentureFriends, Seaya, Kibo Ventures, Banc Sabadell, EA Ventures Plug and Play Fund, and Finaves, the venture capital arm of IESE Business School. The company also benefits from public funding from the European Innovation Council and Spain's State Agency for Research (AEI), highlighting broad confidence in its mission.

NeuralTrust's platform addresses a critical gap in the market. As AI agents proliferate across enterprise functions—from customer service to administrative task automation—and integrate with internal systems and third-party tools, visibility and control become paramount. Many security teams struggle to maintain an accurate inventory of these agents, understand their permissions, or detect malicious manipulation. NeuralTrust offers a unified solution, providing a single pane of glass for monitoring, controlling, and securing all AI agents, thereby mitigating risks associated with unauthorized data exfiltration or actions.

The company's technology operates by inspecting millions of agent interactions daily, identifying and neutralizing approximately 1.2% of malicious activities in real-time. This includes attempts to extract sensitive data or bypass security protocols. NeuralTrust's integrated suite comprises TrustGate, a gateway that centralizes agent communication; TrustGuard, a runtime security engine for threat detection across diverse platforms; and TrustLens, a security posture management layer that continuously monitors agent behavior. This comprehensive approach aims to eliminate blind spots and create a self-reinforcing security posture.

NeuralTrust has already garnered significant traction, serving major clients including Air Europa, Abanca, Iberia, and Banc Sabadell, alongside other global financial institutions, airlines, energy firms, and public sector bodies. A notable 92% of its clients report annual revenues exceeding $1 billion, with 80% based in Europe and 20% internationally. The company's rapid growth is evidenced by its doubling of Annual Recurring Revenue (ARR) in the first quarter of 2026 compared to the entirety of 2025.

The leadership team behind NeuralTrust brings deep expertise. CEO Joan Vendrell previously led AI deployment and security at Mango and held roles at Amazon and McKinsey. CTO Victor Garcia has extensive experience in security architecture within regulated banking and telecommunications sectors, while COO Alejandro Domingo, a former Associate Partner at McKinsey, has a proven track record in scaling startups and driving AI transformations.
