The investment will support the further development of Pallma AI’s platform, which aims to provide centralized security, oversight, and control for enterprise AI and autonomous systems.
London-based Pallma AI, the security layer for agentic enterprise systems, has completed a $1.6 million pre-seed round led by Marathon Venture Capital, with participation from technology leaders from AWS, Meta, Google, and others.
Enterprise adoption of AI is accelerating as large language models and autonomous AI agents move from pilot programs into core operational roles. Many organisations are expected to deploy agentic applications in the near term, increasing reliance on systems that can operate with limited human supervision.
As AI agents take on greater responsibility, this shift also introduces new security and risk considerations. Existing security tools were not designed to manage the probabilistic and adaptive behavior of autonomous systems, which can be vulnerable to prompt manipulation, unintended data exposure, or excessive autonomy. When these systems process sensitive data or are authorised to take actions, errors or misuse can lead to significant operational and security impacts.
Pallma AI addresses these challenges by providing a centralised layer of security, visibility, and control for AI agents. Pavlos Mitsoulis, co-founder and CEO of Pallma AI, explains that the company is building an AI-native security platform designed to protect AI-powered applications by identifying threats in real time and continuously strengthening the security of autonomous systems.
The platform integrates with existing enterprise technology stacks, collects application and system data, and uses AI models to monitor, detect, and mitigate risks such as prompt injection, unintended data exposure, and unsafe agent behaviour in real time. Co-founder and CTO Dionysis Varelas added that the platform combines real-time threat detection with actionable guidance and automated response capabilities, extending beyond a purely passive security approach.
We develop advanced AI models to identify vulnerabilities before malicious actors can exploit them and recommend necessary fixes, ensuring AI applications remain continuously hardened against emerging threats,
Varelas said.
With the new funding, Pallma AI plans to expand its team, accelerate product development, and support growing demand for its AI-powered enterprise security platform.
