About
Sessionize is a speaker and session management platform purpose-built for technology conferences, developer events, and professional gatherings that run a call-for-papers process to select their programming. The platform provides a structured submission portal where event organizers can define submission categories, session formats, and speaker requirements, then collect and organize speaker proposals through a customizable public submission form. Once submissions close, Sessionize's review workflow allows program committee members to evaluate proposals individually, leave comments, and vote on sessions — supporting the distributed review process common in community-driven conferences where multiple volunteers score submissions independently before the committee deliberates on the final agenda.
