Live video platform for hosting webinars, workshops, summits, and creator events with built-in registration and replay.
Crowdcast is a San Francisco-based live video events platform that provides creators, educators, and businesses with tools to host webinars, online workshops, virtual summits, and live Q&A sessions with built-in registration, live streaming, audience interaction, and replay recording. The platform is designed for knowledge-sharing events where audience engagement is central: live polls, Q&A moderation, chat, and the ability for attendees to join on camera create an interactive experience that distinguishes Crowdcast from passive live streaming tools. Crowdcast integrates with payment platforms for paid events and with email marketing tools for post-event follow-up. The platform serves online educators, podcasters, course creators, and marketing teams running virtual lead generation events. Founded in 2013, Crowdcast has focused on the niche of small-to-medium interactive live events rather than competing directly with large virtual conference platforms. The company has served hundreds of thousands of events and competes with Zoom Webinars, Demio, and HeySummit in the virtual event and webinar platform market.
