Fourwaves vs Kaltura: at a glance
What is Fourwaves?
A daily drip of conference-platform polish, with finance filtering and attendee self-service leading.
Fourwaves ships small, single-line changes to its academic conference platform on an almost daily rhythm, publishing each under a bare date. The recent window splits three ways: organization-admin finance tooling, where transactions can now be filtered by organization and by payment gateway; attendee self-service, including a sidebar listing entries already submitted and the ability to add presentations to a personal agenda from the session list; and a run of navigation and consistency fixes. No single change reshapes the product.
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
5.0MEETINGS
A daily drip of conference-platform polish, with finance filtering and attendee self-service leading.
◆ Current state
Fourwaves ships small, single-line changes to its academic conference platform on an almost daily rhythm, publishing each under a bare date. The recent window splits three ways: organization-admin finance tooling, where transactions can now be filtered by organization and by payment gateway; attendee self-service, including a sidebar listing entries already submitted and the ability to add presentations to a personal agenda from the session list; and a run of navigation and consistency fixes. No single change reshapes the product.
◆ Where it's heading
The work concentrates where operators running many events feel friction — untangling payments that arrive through shared gateways, and cutting how much attendees must re-enter across registration and submission forms. A parallel thread smooths the event-day surface, with a live-and-upcoming session panel and consistent back links, icons, and headings across detail pages. Fixes and features are interleaved continuously rather than gathered into releases, so the cadence reads as steady maintenance with incremental reach.
◆ Prediction
Expect more of the same two increments — transaction visibility for organizations running events across shared gateways, and reducing what attendees must re-enter — rather than a headline capability.
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.
