Ceremoni

Ceremoni is built for couples, hosts, and organizers of weddings, parties and celebrations, birthdays, and corporate events. Organizers create an event, pick one of ten designed invitation templates, and add a guest list. Invitations go out directly to WhatsApp, and guests confirm with a single tap while the host tracks who is coming, who hasn't replied, and who needs a follow-up.

The platform also includes a drag-and-drop seating chart and floor plan, a single guest list with contact details, dietary notes, aso-ebi, and plus-ones, and a shared memories gallery where guests upload photos during and after the event. For corporate events, a staff check-in console and attendance analytics replace clipboard check-in at the door. The site says the first event can be set up free with no card required, and a waitlist is currently open.
