Prismm

Overview

Prismm is a U.S.-focused event-technology company that provides cloud software for venue visualization, spatial design, event floor planning, and collaboration. The platform serves venues, hotels, hospitality groups, corporate spaces, event planners, and vendors, combining 2D layouts, photorealistic 3D designs, virtual tours, digital twins, guest-management tools, and collaboration features.

The company is notable for evolving from traditional event floor-plan software into a broader spatial-design platform. Prismm says its system supports more than 5,000 organizations, over 3 million designs and events, a library of more than 150,000 venue floor plans, and over 10,000 design objects. Its current corporate status is that of a Cvent-owned event-technology business.

History

The company was founded in 2011 as AllSeated, an event-planning and floor-plan technology provider. In 2024, AllSeated rebranded as Prismm and repositioned its platform around spatial design technology, including dynamic 3D environments and digital twins. Prismm later became part of Cvent through an acquisition, extending Cvent’s event-technology portfolio with venue visualization and spatial event-design capabilities.

Product Lines

Manufacturing

Prismm is a cloud software company rather than a physical-product manufacturer. Its platform uses venue scans, digital twins, 2D and 3D floor plans, virtual tours, and a library of design objects; the available materials do not indicate physical manufacturing or whether the underlying software development is fully in-house.

Notable Products

• Prismm Plan and Design - Cloud-based event design and planning workspace for creating accurate 2D and 3D layouts, collaborating with stakeholders, and managing event details.
• Prismm Virtual Tours - Interactive 3D venue representations that allow planners and prospects to explore spaces remotely and review different configurations.
• Prismm Spatial Design Platform - Digital-twin technology for presenting physical venues as dynamic, navigable 3D spaces for sales, planning, and design.
• Guest Management and Floor Plan Tools - Tools for assigning seats, handling guest and RSVP information, and producing planning and execution reports.

Reputation

Prismm is positioned by event professionals as a specialized platform for accurate floor plans, venue visualization, and collaboration between planners, venues, vendors, and clients. Its reported strengths include large venue and object libraries, cloud-based sharing, 2D/3D visualization, digital twins, and integrations with event-industry systems. Publicly available materials provide limited independent evidence about customer satisfaction, pricing, or drawbacks; the lack of published pricing also makes direct cost comparisons difficult.
