The app
Your branded app, in every attendee's pocket.
Program, directory, profiles, private messaging, matchmaking. Your logo, your colors, your roles: organizers, partners, corporate, speakers. Your sponsors get their own page.

What you stop doing
The registration spreadsheet
For your attendees
They register through the event form and get their invitation by email.
For you, the organizer
You import a CSV file, and the invitations go out from that file. No more chasing people one by one.
What it takes on your end
Your attendee list as a CSV file. We handle the setup.
The printed list at the door
For your attendees
They show their QR code or wear their badge, and walk right in.
For you, the organizer
No more lists to check off, no more recounts. Arrivals and departures show up live on the dashboard.
The “schedule change” email nobody reads
For your attendees
A notification on their phone, with the program already updated.
For you, the organizer
You write it once, for all attendees or for a specific role.
Attendees who leave without ever meeting
For your attendees
The app suggests profiles for them to meet. With meeting challenges, they get a conversation starter in their own language and confirm the meeting by scanning the other person's QR code.
Relying on the venue's Wi-Fi
For your attendees
The directory, program, and profiles stay available in airplane mode.
For you, the organizer
Check-in keeps running with no network. Everything syncs back up as soon as the connection is restored.
Dashboard
Your event, by the numbers, while it's happening.
Registered and approved attendees, download rate, gender balance, attendance: all in real time. Live polls and live Q&A during sessions, and a satisfaction survey at the end.

Optional
Smart Ruby badges: who's where, to within 3 feet (1 m)
A small Bluetooth device worn on a lanyard. In the app, each attendee sees the people around them and how far away they are, in meters. The badge also handles check-in.
Your event works with or without badges. With badges, about 85% of attendees download and use the app (internal measurement, 2018).
