If you plan events, the Technavio 2017-2021 market research report on global event management software will definitely catch your eye.

According to the tech research and advisory company, the market’s seven key players are:

1. Cvent
2. EMS Software
3. etouches
4. Eventbrite
5. Lanyon Solutions, which merged with Cvent late last year
6. XING Events
7. Ungerboeck Systems International

The report forecasts that these companies will continue to maintain their top positions chiefly through acquiring smaller firms. Case in point: etouches’ recent addition of smartwear startup Loopd.

So, if you’re already using these companies, it looks like you’re in good company.

“Event-management software is used for the management of academic conferences, exhibitions, and trade shows,” Amit Sharma, Technavio’s lead analyst for enterprise application research, says in the report. “The global event-management software market size is projected to grow to USD 1.64 billion by 2021, driven by the rise in the number of corporate events and the rising prominence of social networking sites.”

Cloud-based event-management software has grown to become an important tool for those in the event-planning industry, offering planners a full-circle, end-to-end system that often includes registration, ticketing, booking, mobile resources, gamification, social media, real-time analytics and CRM data flow.

“Some of the major factors responsible for the increasing adoption of cloud [event-management software] solutions is the benefits associated with it such as its ability to function without additional hardware or software, inexpensiveness, and easy to access even from remote areas,” Technavio says in its report. “In addition, since the cloud model reduces the upgrading and maintenance costs related to the on-premises technology, the cloud solutions is gaining popularity on a global level.”

In addition to the big seven, other leading software companies are Bizzabo, CadmiumCD, Certain, Constant Contact, Profit Systems, iRez Systems, KweekWeek, Lyyti, Member Solutions, MIE Software, PlanetReg, PlanningPod and TPNI.

The report also predicts steady global market growth with a 10 percent compound annual growth rate through 2021 due in large part to increasing demand for online registration and online payment methods, which not only automates the process, but can also source suppliers.

Technavio cites “increasing comfort and satisfaction of attendees, reduction in the cost of an organization, and availability of options to understand the spending patterns of customers” as the factors driving this demand.
