About Kaltura
Kaltura goes all-in on agentic AI video — Event OS, avatar roleplay, and an open-sourced AI Agent Skills suite.
Kaltura is in the middle of a sharp pivot toward agentic AI for rich-media platforms. In a single month it has open-sourced an AI Agent Skills suite (so any third-party AI agent can build rich-media experiences), introduced Event OS for AI Agents (natural-language event creation and orchestration), unveiled an avatar-powered roleplay solution for enterprise training, and is presenting an Agentic Revenue Engagement Platform at Forrester. The releases are tightly aligned around one thesis.
