What is Fourwaves?

Fourwaves is closing the gaps around its payments layer and its form editor at the same time.

Fourwaves publishes a near-daily, one-line changelog covering small changes to the conference organiser's admin surface. The August window is dominated by payments and money administration: transaction filtering by organisation and by payment gateway, the Free plan surfaced in the upgrade checkout, and Authorize.net added as a supported processor. The two newest entries move elsewhere — self-service account creation from the sign-in page, and a guard that blocks deleting fields, sections, or choices still referenced elsewhere in an event, with a warning naming what depends on them.

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 vs Kaltura: editorial side-by-side

Fourwaves
MEETINGS
5.0

Fourwaves is closing the gaps around its payments layer and its form editor at the same time.

◆ Current state

Fourwaves publishes a near-daily, one-line changelog covering small changes to the conference organiser's admin surface. The August window is dominated by payments and money administration: transaction filtering by organisation and by payment gateway, the Free plan surfaced in the upgrade checkout, and Authorize.net added as a supported processor. The two newest entries move elsewhere — self-service account creation from the sign-in page, and a guard that blocks deleting fields, sections, or choices still referenced elsewhere in an event, with a warning naming what depends on them.

◆ Where it's heading

The work is aimed at multi-event organisations rather than single-conference organisers; transaction filtering and a second payment processor only matter if you run several events through shared gateways. The referential-integrity guard on form fields points at the same maturity problem from the other side — events configured deeply enough that deleting a field silently breaks something downstream, which is a complaint you only get once customers build complex forms. Individually each change is minor; together they describe a platform being made to hold more events per customer.

◆ Prediction

Expect the payments thread to continue — further gateway options or per-organisation payment configuration are the natural next step now that transactions can be filtered by gateway. The date-stamped daily format suggests the cadence holds regardless of the size of what ships.

8.8

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.
