Fourwaves vs Kaltura: at a glance
What is Fourwaves?
Fourwaves adds custom domain support for event websites, removing the hosted-subdomain constraint for conference organizers
Fourwaves is shipping consistent weekly improvements to its conference management platform: custom domain mapping for event websites, an auth gate before registration forms, and presentation/participant visibility parity between the mobile app and event website. The platform is also tightening workflow correctness — fixing reviewer workload counts in assignment confirmation and fixing raw markup in bio rendering.
What is 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.

Fourwaves adds custom domain support for event websites, removing the hosted-subdomain constraint for conference organizers
◆ Current state
Fourwaves is shipping consistent weekly improvements to its conference management platform: custom domain mapping for event websites, an auth gate before registration forms, and presentation/participant visibility parity between the mobile app and event website. The platform is also tightening workflow correctness — fixing reviewer workload counts in assignment confirmation and fixing raw markup in bio rendering.
◆ Where it's heading
Custom domain support moves Fourwaves toward white-label territory — event organizers can now present a fully branded web presence without the hosted subdomain being visible. The sign-in gate before forms suggests the platform is building more secure, verifiable attendee flows. Together these point to a push up-market toward professional and academic conference organizers.
◆ Prediction
Following custom domains, additional white-label features such as branded emails and registration confirmations, or improvements to the abstract submission and review workflow, are the most likely next moves.
Kaltura
8.8MEETINGS
Kaltura goes all-in on agentic AI video — Event OS, avatar roleplay, and an open-sourced AI Agent Skills suite.
◆ Current state
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.
◆ Where it's heading
The arc is clearly from a video platform into an agentic-AI orchestration layer that happens to specialize in video. Kaltura is staking out the position that video, events, training, and revenue engagement should all be run through AI agents talking to its platform — and is willing to open-source the agent-skills layer to make Kaltura the default endpoint for rich-media agents.
◆ Prediction
Expect a paid agent runtime or pricing model on top of the open-sourced skills, deeper avatar/roleplay options for enterprise L&D, and Event OS plug-ins for major collaboration platforms (Teams, Slack, Google Workspace). The next big tell will be how serious enterprise adoption of Event OS becomes versus staying a demo-stage capability.
