Direct peers

• Social Tables: Event design software platform for floor planning, seating, and diagramming. Already a wholly-owned subsidiary of Prismm (formerly Allseated) and the closest direct competitor in collaborative event layout, serving the same planners and venues.
• Bizzabo: Enterprise event experience platform offering registration, agenda, and engagement tools for in-person, hybrid, and virtual events. Comparable as a competing SaaS platform targeting the same event organizer and marketer buyer personas.
• Tripleseat: Sales and event management platform for restaurants, hotels, and unique venues. Directly comparable because it serves the same venue and event planner customer base with booking, diagramming, and proposal workflows for private events.
• Planning Pod: Event management platform for venues and planners offering floor plans, seating charts, timelines, and booking tools. Comparable as a SaaS alternative for the same event planner and venue customer segments.
• Priava: Cloud-based venue and event management software for convention centers, hotels, and cultural venues. Overlaps with Prismm on venue sales, event booking, and diagramming workflows for enterprise venue operators.
• easyRAUM: Germany-based event planning and venue management software acquired by Allseated (now Prismm) in January 2021. Directly comparable as a regional event design and diagramming solution with overlapping feature set for European venue and planner markets.
• Aventri: Enterprise event management platform for registration, agenda, and attendee engagement. Comparable as a competing SaaS platform targeting enterprise event teams, with overlapping capabilities around event planning, venue management, and digital workflows.

Others

• Matterport: 3D digital twin capture platform and Prismm's technology partner since 2021. Adjacent/ecosystem comparable: Matterport provides the spatial capture hardware and processing, while Prismm layers event-specific diagramming and collaboration on top of Matterport twins.

Broad incumbents

• Cvent: Prismm's parent company and the dominant enterprise event management platform. Cvent serves event organizers, venues, and planners with registration, venue sourcing, and event marketing — overlapping with Prismm's diagramming and venue visualization use cases but at much broader scope.
• Eventbrite: Public event ticketing and discovery platform with self-service event creation tools. Broader incumbent serving a wider range of event organizers and consumer-facing events, with limited overlap in enterprise venue diagramming but comparable event-planning SaaS category.
