I would like to obtain a formal business quote for a conference with 20,000 attendees.

Yes. Certain positions itself as enterprise-grade and scalable for large, multi-day conferences, including events with tens of thousands of attendees. Public details do not publish exact per-event attendee limits; a formal sales quote is typically required to confirm availability, pricing, and any architecture considerations for a 20,000-attendee conference.

What this means:

• Likely requires an Enterprise-level deployment with data orchestration, Event Intelligence, and robust security.
• A precise quote comes from Certain’s sales team after you share event specifics (location mix, virtual/hybrid components, integrations, support needs, SLA requirements, etc.).

Sources:

• Certain Event Intelligence
• Certain Oracle Event-Marketing Benchmark Report
• Transaction Pricing Policy

Would you like me to initiate a formal enterprise quote request with the details of your 20,000-attendee conference, or prepare a requirements checklist to share with sales?
