NeuralTrust closes $20M to expand AI agent security platform

NeuralTrust, a platform for securing AI agents, has raised a $20 million seed financing round, led by Alstin Capital, with participation from VentureFriends, Seaya, Kibo Ventures, Banc Sabadell, EA Ventures Plug and Play Fund, and Finaves, the venture capital fund of IESE Business School. NeuralTrust also receives public support from the European Innovation Council and Spain’s State Research Agency (AEI).

The investment comes as enterprises expand the use of AI agents across business functions. As these systems are deployed across multiple teams, platforms, and vendors, organisations are placing greater emphasis on visibility, governance, and security. Industry analysts expect governance and oversight requirements for AI agents to become increasingly important as adoption continues to grow.

Founded by Joan Vendrell (CEO), Victor Garcia (CTO), and Alejandro Domingo (COO), NeuralTrust provides a unified platform that enables organisations to discover, monitor, govern, and secure AI agents across their environments.

The company currently inspects millions of AI agent interactions every day. Approximately 1.2 per cent of these interactions require intervention, including attempts to extract sensitive data, manipulate tools, or bypass operational controls. These threats are identified and mitigated in real time.

Joan Vendrell, co-founder and CEO of NeuralTrust, said that as AI agents become increasingly integrated into enterprise operations, organisations are working to establish the controls and governance mechanisms needed to support their use. He added:

Our mission has not changed since day one: turn AI security into a strategic advantage for the enterprises that will define the next decade.

NeuralTrust’s platform combines three products: TrustGate, which manages agent traffic across models and tools; TrustGuard, which provides runtime security for AI agents; and TrustLens, which offers visibility into agent deployment and behaviour. Together, they provide a unified approach to AI agent governance, security, and monitoring.

The company also contributes to AI security research and has identified and documented new attack techniques, including the multiturn jailbreak method known as “Echo Chamber” and the multimodal attack vector “Semantic Chaining,” both of which have been incorporated into the OWASP AI Security Project taxonomy.

The new funding will be used to further integrate the company’s platform, expand its engineering team, and broaden support for the growing range of AI models, tools, and platforms being adopted by enterprises.
