Momentus (formerly Ungerboeck) is venue management software built for convention centers, stadiums, arenas, and campuses. Teams whose main need is attendee-facing event registration, ticketing, check-in, and badge printing often look for a dedicated event platform instead. The strongest Momentus alternatives for that job are Accelevents, Cvent, Stova, Bizzabo, Swoogo, RainFocus, and Eventbrite. The right choice depends on how much you value ease of use, CRM integration, pricing transparency, and whether you need venue operations or attendee experience.
Here is how the leading options compare.

Why teams look for a Momentus alternative
Momentus is a capable venue management platform. The most common reason teams evaluate alternatives is a mismatch of job to be done. Momentus is organized around the venue: booking calendars, space utilization, work orders, catering, and billing for convention centers, stadiums, arenas, and campuses. Teams whose central need is the attendee-facing event, that is, registration, ticketing, check-in, and badge printing, often want a platform built specifically for that.
Other common triggers include wanting registration data to flow natively into a CRM like HubSpot or Salesforce, wanting a faster and more intuitive setup for lean teams and seasonal staff, and wanting one platform that covers in-person, virtual, and hybrid events.
Note on naming: Momentus was formerly called Ungerboeck, so you will see both names used interchangeably. Searches for an "Ungerboeck alternative" and a "Momentus alternative" are looking for the same thing.
The 7 best Momentus alternatives
1. Accelevents
Best for lean event teams that want an all-in-one platform centered on the attendee experience. Accelevents covers registration, ticketing, onsite check-in, a drag-and-drop badge designer, event websites, exhibitor and sponsor tools, and engagement for in-person, virtual, and hybrid events. It integrates natively with HubSpot, Salesforce, and Marketo, plus Zapier and an open API, so registration data flows into your CRM for marketing and sales without manual exports. It is recognized by G2 with a Highest Quality of Support award and is built to launch fast. The main reason it would not fit: it is not a venue operations suite, so if your core need is booking and managing a building, that is a different category.
2. Cvent
Best for large enterprises running complex, high-volume event programs that need depth across sourcing, registration, and onsite. The trade-offs buyers most often cite are cost, multi-year contract length, and a steeper learning curve.
3. Stova
Best for mid to large in-person and hybrid events. Stova (formed from the merger of several event tech brands) offers deep registration and onsite capabilities and is oriented to enterprise setup.
4. Bizzabo
Best for brand-led conferences and field marketing teams that want a polished attendee experience and strong integrations with Salesforce, HubSpot, and Marketo. Pricing sits at a premium tier.
5. Swoogo
Swoogo logo — registration-first event platform
Best for registration-first teams and agencies that want flexible, well-built registration without a heavy all-in-one footprint. Lighter on virtual and in-event engagement than some alternatives.
6. RainFocus
Best for very large enterprise conferences that need a highly configurable platform and have the resources for a heavier implementation.
7. Eventbrite
Best for simple, public, ticketed events. Easy to start, but typically too basic for complex B2B registration, badging, and CRM workflows.
How to choose the right Momentus alternative
Work through four questions in order:
- Venue operations or attendee experience? If you need to manage a building or campus, you are in Momentus's category and should compare venue platforms. If you need registration, check-in, and badging, compare event platforms like the ones above.
- Does registration need to flow into your CRM? If yes, prioritize platforms with native HubSpot or Salesforce sync so marketing and sales work from the same data.
- How lean is your team? If you train seasonal staff each cycle, weight ease of use and setup speed heavily.
- What is your event mix? If you run in-person, virtual, and hybrid, a single platform that covers all three reduces tool sprawl.
For most teams leaving Momentus specifically for the registration job, the shortlist comes down to ease of use, native CRM integration, and speed to launch. That is the lane Accelevents is built for.
Switching from Momentus
Migrating registration to a new platform comes down to three steps: export and map your existing data, rebuild your registration types and required fields in the new platform, and run a test event before your next on-sale date. Accelevents supports data import, includes onboarding and training, and provides live support so lean teams can move without a heavy implementation lift.
