doo

doo is a German software company offering a modular, cloud-hosted platform for running business events. It handles gatherings from ten guests to several thousand, for internal or external audiences, and follows each attendee from the first invitation through to the event itself.

What doo offers

• Invitation management — personalised emails lead guests to booking forms that are already filled in, backed by an event landing page in the organiser's own design.
• Registration and ticketing — no-charge or paid tickets with payment handling, custom ticket categories, add-on products, voucher codes and optional QR-code tickets.
• Guest management — one central record of every participant, pulling in data from the other apps linked to the event.
• Personalised attendee journey — tailored communication, tickets and individual agendas before, during and after the event.
• Integrations and reporting — connects to existing IT systems, event apps and platforms, with automated stakeholder messages and configurable reports.

Who it works with

doo is built for B2B event organisers; one published case covers lead qualification at the FIBO 2025 trade fair. The firm also runs demo webinars explaining its main features.
