NeuralTrust has raised $20 million in seed funding to secure the fast-growing swarm of AI agents being deployed inside large enterprises, in what the Barcelona- and London-based company calls the largest cybersecurity seed round ever raised by an EU company.
Backers and structure
The round was led by Alstin Capital, with participation from VentureFriends, Seaya, Kibo Ventures, Banc Sabadell, EA Ventures Plug and Play Fund and Finaves, the venture fund of IESE Business School. NeuralTrust also draws public support from the European Innovation Council and Spain's State Research Agency. The capital will fund deeper product integration, more engineers and wider coverage of the AI models and tools enterprises are adopting.
Securing autonomous agents
Founded in 2024 by Joan Vendrell, Victor Garcia and Alejandro Domingo, NeuralTrust runs a three-part platform: TrustGate to manage agent traffic across models and tools, TrustGuard for runtime security, and TrustLens for visibility into agent behaviour. The company says it inspects millions of agent interactions daily, roughly 1.2% of which require intervention against data-extraction, tool-manipulation or control-bypass attempts.
A widening security category
The raise underscores how quickly AI-agent governance has become its own security discipline, mirrored by fresh activity such as Tenet Security's debut and Cisco's Cloud Control platform. NeuralTrust's clients already span global banks, airlines and government agencies across Europe.
