At its core, EBMS stands for Event Business Management Systems, a class of software designed to help organizations plan, manage, and execute every aspect of events and venues through a single, integrated platform. Originally the name of Ungerboeck’s flagship solution, EBMS provided tools to streamline bookings, scheduling, registration, financials, and resources, giving event professionals a centralized system to run complex operations with efficiency and clarity. Over time, as the product evolved into a cloud enabled, browser based platform, the EBMS name became synonymous with Ungerboeck’s approach to event and venue management, laying the foundation for what the Momentus platform is today.

History of EBMS Software, including Ungerboeck & Momentus
1985: The Foundation of EBMS Software
Ungerboeck Systems Inc. Is Founded
A young couple, Catherine and Dieter Ungerboeck, founded the company as a small startup in Chesterfield, Missouri. At the time, the company was building custom solutions for the process manufacturing industry. The small team was led by Dieter Ungerboeck, in charge of customer relationships, and his wife Catherine, who was leading the development of the software. These early solutions laid the groundwork for what would later become EBMS software for complex operational environments. 1989: The First EBMS Software for Event and Venue Management
1989
The First Venue and Event Management System Is Created
Ungerboeck Systems Inc. received a request from the St.Louis Convention and Visitor Bureau and Los Angeles Convention and Visitors Bureau to build a custom solution for venue and event management. Following the advice of IBM, a business partner at the time, Ungerboeck took on the two projects and secured ownership of the code created. The software was named EBMS, or Event Business Management Software, marking the beginning of purpose-built EBMS software for the event and venue industry. The company has kept on improving the platform to answer the needs of the venue and events industry ever since.
2012: Modernizing EBMS Software for Browser-Based Access
The Rebrand to Ungerboeck Software International
The company then completely revamped the user experience of its venue and event management software. With the release of its browser-based Version 20, the company rebranded to Ungerboeck Software International and the software name became Ungerboeck software. This shift toward browser-based EBMS software improved accessibility, usability, and scalability for event and venue teams.
2019: A Customer-Centric Approach to EBMS Software
The Birth of Customer-Centric EBMS Software
Ungerboeck Software International rebrands to Ungerboeck as the company worked on major software releases to significantly elevate its customers' experiences. By focusing on mobility, agility, and connectivity, Ungerboeck continued evolving EBMS software to meet the demands of modern event and venue operations. Innovative mobile solutions allowed for increased productivity and real-time information gave users the power to be more customer-centric than ever before.
May 2021: Expanding EBMS Software Capabilities
The Merger of Ungerboeck and EventBooking
Ungerboeck merged with EventBooking, a software provider of event and venue management software tools, to offer customers an integrated set of capabilities that further enhanced its world-class solutions. This merger expanded EBMS software functionality by connecting event marketing, booking workflows, and operational data in a single ecosystem.
November 2021: Strengthening EBMS Software for Global Markets
Ungerboeck Acquires ShoWorks and Priava
Ungerboeck acquired both ShoWorks and Priava. ShoWorks was a technology system used by 75% of all fairs in North America to manage exhibits and competition entries and Priava was a cloud-based venue and event management system with strong representation in Australia, New Zealand and the United Kingdom. Unifying these platforms strengthened EBMS software capabilities across global event and venue markets.
2022: Risk Management Added to EBMS Software
Ungerboeck Acquires Risk Management Tool
Ungerboeck acquired the products developed by risk management agency Reliance Risk to debut an industry-first application for mitigating risk to events and venues. The acquisition of RiskSense101 and VRM360 added risk assessment and compliance tools directly into EBMS software workflows.
January 2023: EBMS Software Becomes Momentus
Ungerboeck Unveils Name Change to Momentus
The rebrand to Momentus Technologies marked a major evolution in our company’s history. The Momentus brand unified EBMS software solutions under one connected platform designed for modern event and venue management.
