Overview

plazz AG is a German software company focused on event and employee-communication applications. Its core offering is a modular, cross-platform event-app platform covering pre-event information and registration, attendee engagement, event communications, and check-in for live, virtual, and hybrid events. The company also offers Polario for internal employee communication, positioning it beyond event-only software.

History

plazz AG was founded in 2007 in Grünwald near Munich. Jürgen Mayer joined as shareholder and CEO in 2010, after which the company established a development center in Erfurt and focused on mobile-app, server, cloud, and UX/UI development. The company launched its Mobile Event App SaaS offering in 2013 for corporate events, conferences, and meetings. It later expanded its portfolio with Polario for employee communication, registr for participant registration, and a check-in application.

Reputation
