No matter the event — from weddings and dinner parties to corporate keynotes and large-scale conferences — we offer a platform that lets you showcase, sell, and plan using beautiful, dynamic 3D digital twins.

Several chairs are arranged around a table in a banquet hall. The 3D rendered chairs and tables represent how Prismm can help solve spatial design problems for event planners and venues.

“Including Allseated (now Prismm Platform) as part of our selling process has given us the opportunity to show current and prospective clients our spaces in various setups, giving them the ability to envision their event with us before it takes place, without having them come onsite. This sets us apart from our competitors.”
