Alludium Commercial Launch

Catenai PLC (AIM: CTAI), the AIM quoted provider of digital media and technology, announces that, Alludium Ltd ("Alludium") will launch its AI Agent collaboration platform at Web Summit in Lisbon from 10-13 November 2025.

Alludium (alludium.ai) is developing an Agent Operating System that enables users to create, deploy and share custom agents through conversation, no coding required. Unlike traditional AI tools that operate in isolation, Alludium's platform allows multiple AI agents to collaborate with each other and with users, building institutional memory and automating workflows across organisations. The platform addresses a growing market need for AI solutions that can scale beyond individual use cases to enable human-AI team collaboration. Alludium's technology allows agents to communicate, coordinate tasks, and share intelligence to solve complex problems together.

WebSummit is one of the world's largest technology conferences, attracting over 70,000 attendees from 150+ countries, including Fortune 500 executives, leading venture capital firms, and international media. From over 18,000 applicants, Alludium has been selected to participate in the WebSummit's prestigious 'ALPHA' Startup Programme. The company will exhibit on Thursday, 13 November 2025, providing an opportunity to publicly demonstrate the platform to potential customers, investors, and enterprise technology partners.

The launch will operate on a waitlist model, enabling Alludium to manage early access and gather user feedback as the platform scales. Interested parties can register at www.alludium.ai ahead of the public launch.

Catenai holds 1,439,036 ordinary shares in Alludium representing approximately 13% of the issued share capital of Alludium.

John Frizelle, Founder Alludium commented: "We are excited to see Alludium reach this important milestone with its public launch at WebSummit. The AI agent market is experiencing rapid growth, and Alludium's unique approach to multi-agent collaboration positions it well within this expanding sector. Being selected for WebSummit's Startup Programme validates the strength of the team and the platform's potential. This launch represents a significant step forward for Alludium."

John Farthing, CEO of Catenai commented: "Congratulations to the Alludium team on reaching this significant commercial milestone. We are extremely excited about Alludium's launch and encouraged with the emphasis on practical, real-world application. This is just the beginning of the journey in a rapidly growing and transformational market and we look forward to observing the platform's continued development and the impact it will have across industries."
