NeuralTrust, a Barcelona-based cybersecurity company providing security and governance solutions for AI agents, has raised $20 million in seed funding. The round was led by Alstin Capital, with participation from VentureFriends, Seaya, Kibo Ventures, Banc Sabadell, EA Ventures Plug and Play Fund, and Finaves.
Securing Enterprise AI Agents
The investment comes as enterprises increasingly deploy autonomous AI agents across business operations. NeuralTrust helps organizations gain visibility into AI systems, manage permissions, detect threats, and enforce security policies across different models, platforms, and tools.
AI Security Platform
The company’s platform combines three core products: TrustGate, which controls AI agent interactions; TrustGuard, which monitors and blocks threats in real time; and TrustLens, which provides visibility into agent activity and security posture across the enterprise.
NeuralTrust processes millions of AI agent interactions daily, identifying and preventing malicious actions such as data extraction attempts, tool misuse, and unauthorized behavior.
Growing Enterprise Adoption
Customers include major organizations such as Air Europa, Abanca, Iberia, and Banc Sabadell, along with global financial institutions, airlines, energy companies, and public-sector organizations. During the first quarter of 2026, the company reported growth that exceeded its entire 2025 annual recurring revenue.
NeuralTrust has also established partnerships with organizations including KPMG, Capgemini, Sopra Steria, Bentengo, and M3Corp to expand enterprise adoption.
Expansion Plans
The new funding will support product development, platform integration, engineering growth, and broader coverage of AI models and agent ecosystems. The company plans to strengthen its position in the European market while expanding internationally.
“AI agents are now part of enterprise operations, but the controls protecting them are still catching up,” said Joan Vendrell, Co-Founder and CEO of NeuralTrust. “This round allows us to keep building the infrastructure layer that makes AI adoption measurable, governable, and safe. Our mission has not changed since day one: turn AI security into a strategic advantage for the enterprises that will define the next decade.”
"AI agents are entering enterprise infrastructure faster than security teams can adapt, so the window to establish control is now. What convinced us to lead this round was not just an exceptional product, but also the team's clarity on where the real problem sits. They've built a genuine control layer, not another point solution, and enterprises can operationalize it today. We believe securing AI agents in enterprise infrastructure is becoming one of the defining problems in cybersecurity and NeuralTrust is best placed to own it," says Alexander Meyer-Scharenberg, Partner at Alstin Capital.
