Digital Event Platform with Autonomous Guest Management

Through an integrated digital ecosystem that automates the entire event lifecycle: guest list management, personalized email invitations with one-click RSVP, automatic seating-plan updates and a real-time dashboard. Manual Excel upkeep and individual emails were replaced by a fully automated workflow — from 23 work hours down to 84 minutes per event.

Node.js/Express on the backend, PostgreSQL as the database and vanilla JavaScript on the frontend — deliberately without React or Vue, because maintainability matters more to a small team than technical complexity. Nodemailer powers the email engine with HTML templates and .ics calendar invitations, and a relational graph model drives the intelligent seating plan.

Every event client receives a password-protected portal for real-time guest lists. Changes — new guests, cancellations, special requests — propagate instantly through the entire system: seating plan, catering overview and email automation. RSVPs run through personalized one-click links with menu selection and an allergy filter. The open rate of the personalized invitations stands at 97%.

Yes — the principles behind the Élysée platform (process automation, client portal, email workflows, real-time dashboards) transfer to any industry. Kuroko Labs analyzes your existing processes and develops a tailor-made solution. The initial consultation and potential analysis are free of charge.

Six weeks from concept to launch. Thanks to the modular architecture and the decision to avoid unnecessary framework complexity, the platform was developed quickly and tested iteratively with the Élysée team. Since launch, more than 2,400 guests have been processed and over 7,000 automated emails sent — without a single unplanned outage.
