Offline-first Event OS

The operating system for high-volume events

Guest lists, tables, talent advancing, and live event control in one offline-first platform. Built for teams that need reliability when it matters most.

Events are chaos by default.
Listium makes it predictable.

Listium replaces the panic that kills vibes, revenue, and credibility. Every team sees the same info no matter how loud the room is.

No more WhatsApp guest lists or paper hash marks at the door.
No more double-seated tables because bookings lived in DMs.
No more multi-spreadsheet advancing or missed riders.
No more radios and email threads trying to sync FOH/BOH.

Without Listium

  • Guest lists in WhatsApp, email, and janky spreadsheets.
  • Table inventory in AirTable, shared docs, or someone’s head.
  • Advancing across email chains with no audit trail.
  • Show control on radios, whiteboards, and memory.
  • Zero shared data, zero offline resilience.
Product Suite

One platform. Four purpose-built workspaces.

Data flows across door, VIP, production, and Command without brittle exports.

Door & Check-In

Guest Lists

Offline-first check-ins and live stats for high-volume door teams.

Tiered lists & quotas

Segment AAA, VIP, GA, press, and crew with caps, notes, and attribution intact.

Instant search & scan

Type-ahead search, QR/barcode scanning, and tactile feedback tuned for dark environments.

VIP & Revenue

Table Service

Deposit-backed reservations and revenue automation for VIP ops.

Inventory & floor maps

Mirror venue templates or build per-event layouts with live status colors and timers.

Unified ledger

Capture deposits, pre-auths, comps, and adjustments with audit-ready tracking for every promise.

Artist & Production

Advancing

One advancing board for production, talent, and hospitality teams.

Kanban across statuses

Drag slots between requested, confirmed, advanced, on-site, and settled to broadcast state instantly.

Structured riders

Tech, hospitality, and travel requirements live next to contact info, guest quotas, and documents.

Run of Show

Show Control

Real-time command center for multi-room cues and incident tracking.

Now/Next timeline

Color coded segments with audio, lighting, and experiential cues for every room.

Incident logging

Tap-to-log issues with escalation paths that ping the right lead and log outcomes.

Command HUD

Ops Timeline keeps the whole venue in one view.

This is the brain Directors of Ops rely on. Every phase of the night flows through Command HUD with undo safety nets and KPIs pinned where you need them.

Before doors

Promoters preload quotas, advancing locks riders, and VIP Host tunes mins. Local mirroring means every change hits devices instantly.

During the show

Door, table, and show control teams work off one HUD with undoable actions. Incidents, late arrivals, and last-minute holds broadcast across devices.

After hours

Settlement packets, table ledgers, and artist notes are ready before teardown. Command tiles roll up KPIs for finance, talent, and safety.

Offline-first

Stays online when
Wi-Fi doesn’t.

Listium keeps a copy of your night on every device, queues actions the moment they happen, and pushes updates to the rest of the crew within seconds.

Offline-first reads
Every device keeps tonight’s data on hand for instant responses—even backstage.
Reliable sync
Updates save immediately and push once you're back online, so no action is lost.
Live device updates
All tablets and phones refresh within seconds when something changes.

Built for every role.

Role-based playbooks baked into the HUD.

Co-designed with venue partners

Owners & GMs

Command KPIs, pacing alerts, and nightly recaps make it easy to see the whole club from one HUD.

  • Door flow + table revenue in real time
  • Auto-generated settlement packets

Door & Security

Offline guest lists, undo safety nets, and check-in logging tuned for sub-second responses.

  • Offline-first check-ins
  • Incident + ejection log with evidence
  • Crew alerts that cut through radio chatter

VIP Hosts & Sales

Hold timers, deposit links, and dynamic pricing keep utilization high without spreadsheet acrobatics.

  • Dynamic mins with guardrails
  • Self-serve booking links
  • Ledger ties every comp to a guest

Production & Talent

Advancing boards, AI rider import, and task tracking keep artists on time even if Wi-Fi drops.

  • Automatically import tech and hospitality riders with AI
  • Project statuses across departments
  • Structured riders & hospitality counts

Pricing that flexes with your venues

Starter, Professional, and Enterprise tiers scale per venue so a second room or new market doesn’t break the budget. Table Service and Artist & Production modules stay optional add-ons.

Common questions

Everything you need to know about the platform and billing.

Still have questions? Chat with our team

Does everything really work offline?

Yes. Each device stores tonight’s data locally, so check-ins and edits never stop. Once service comes back, everything syncs in roughly a second and every team sees the same numbers.

How fast can we launch?

Most teams are live in one week. Rebuild table inventory, map roles, and train each crew with hands-on sessions.

What about privacy?

Data stays inside your Listium workspace with staff-level access controls, device approvals, and full audit logs. Regional residency requirements are available when needed.

Share your calendar, we'll map the rollout.

Import history, stage devices, rehearse door + VIP + production flows, and lock pricing before go-live.
