If you're sizing up an alternative to Momentus (formerly Ungerboeck), you've likely outgrown one of these: the per-seat math, the missing production primitives, or the workflow that doesn't survive the second show. Here's what holds from pitch through wrap, and what's worked for teams that moved.

Credit where it's due before we talk alternatives. Momentus (formerly Ungerboeck) earned its place. Here's where it delivers.
These are the gaps we hear from teams weighing an alternative. Your run-of-show may vary.
Momentus publishes a clear center of gravity: the venue. Enterprise and Elite editions manage the space diary, event coordination and back office for convention centers, stadiums, arenas and performing arts centers; Momentus Ticketing adds white-label enterprise ticketing and WeTrack adds incident, risk and operations tracking. Decades of Ungerboeck heritage sit underneath it. Atlas starts from the other end of the same show: the crew on the floor. Compass carries shifts, punches, incidents, custody and the gate offline-first today; Legend carries the courses, certifications and SOPs; Gateway carries the public marketplace. The operator console that ties the office side together is coming.
Momentus manages the venue's calendar and back office. Compass is in the pocket of the crew building the show: punches, incidents, custody moves and gate scans land offline-first on one org record.
Legend keeps courses, certifications and SOPs on the same record the field writes, and Gateway faces the public with talent, gigs and RFPs. A venue management system has no reason to carry either.
Pricing is public and per org with unlimited users. Surge headcount for a load-in week does not change the bill.
The path teams take to move off Momentus (formerly Ungerboeck).
