About WebinarStack
Built by Conversion Stack LLC, Colorado, United States
WebinarStack is a hosted automated webinar platform. You record a webinar once, and it runs on a schedule after that — recurring sessions or just-in-time sessions that start minutes after someone registers — while the follow-up each attendee gets depends on what they actually did while watching.
Who it is for
Course creators, coaches and other sellers who use a webinar to sell an offer and want it to keep working without presenting live every time. Teams that already run evergreen webinars on another platform and want deeper, behaviour-driven automation use it too.
What it does
- Schedules a pre-recorded webinar so it runs on recurring or just-in-time sessions.
- Makes sessions feel live to attendees, with scheduled start times and timed moments such as chat and offers during playback.
- Tracks what each attendee did — registered, joined, how far they watched, whether they clicked the offer — and triggers emails, webhooks and offers from that behaviour.
- Publishes replays automatically after a session.
- Exposes the same capabilities to your own systems and to AI agents through a REST API, signed webhooks and an MCP server.
