A friendly voice that confirms
every attendee personally.
Email reminders land in spam. Text messages get ignored. A warm, human-sounding phone call gets a real answer: confirmed, rescheduled, or cancelled. Attendees respond because the voice sounds real — not robotic.

Registrants don't show up
40–60% of free event registrants never attend. You order catering, book a venue, and prep materials for a crowd that doesn't materialize.
Email reminders go unread
Open rates for event reminder emails average 20%. The other 80% never see your message. You have no way to know who's actually coming.
Manual follow-up doesn't scale
Calling 500 registrants individually takes days. Your team can't do it, and by the time they try, it's too late to adjust plans.
How Stellar helps
Multi-touch voice confirmations
Up to 3 natural-sounding calls per attendee at intervals you choose. Each call feels personal, not scripted. The moment someone confirms, remaining touches are cancelled automatically.
Batch operations at scale
Upload a CSV or connect Eventbrite. Stellar reaches hundreds of attendees in parallel — each one getting a call that sounds like a real person, not a phone blast.
Real-time tracking dashboard
Watch confirmations roll in live. Know your exact headcount, cancellation rate, and no-answer count days before the event.
