How much do event organizer attendee lists cost?

Event organizers typically charge $5,000 to $20,000 for attendee lists, often bundled with sponsorship packages. Some events don't sell attendee data at all.

Are WhoGoes lists as accurate as organizer lists?

WhoGoes lists are sourced from public LinkedIn posts, so every contact has verifiable proof of attendance. Organizer lists include all registrants (including no-shows), so WhoGoes data can actually be more accurate for identifying who truly engaged with the event.

Can I get attendee lists for events I didn't sponsor?

Yes. WhoGoes doesn't require a sponsorship or any relationship with the event organizer. You can access attendee data for 1,200+ events regardless of your sponsorship status.

When are WhoGoes lists available compared to organizer lists?

WhoGoes lists build in real-time as attendees post about the event on LinkedIn. You can start accessing data before, during, and after the event. Organizer lists are typically shared days or weeks after the event ends.

Event organizer attendee lists have been the gold standard for post-event outreach — but they come with a hefty price tag and strings attached. Most organizers bundle attendee data with sponsorship packages starting at $5,000, and some events don't share attendee data at all.

WhoGoes offers an alternative: verified attendee lists sourced from public LinkedIn activity, available for any of 1,200+ trade shows, starting at just $29.

The Problem With Organizer Lists

Event organizer lists have three major drawbacks:

Cost — $5K–$20K per event, usually bundled with sponsorship. For companies attending 5–10 events per year, that's $25K–$200K just for attendee data.
Timing — Most organizers share lists days or weeks after the event. By then, your competitors have already followed up.
Quality — Organizer lists include everyone who registered, including no-shows and people who used fake emails at registration. There's no way to verify who actually attended.

Why LinkedIn Proof Matters

WhoGoes takes a different approach. Instead of relying on registration data, it monitors public LinkedIn posts about trade shows. Every contact in a WhoGoes list has verifiable proof that they engaged with the event — they posted about it, shared photos, or mentioned attending.

This means you're reaching out to people who were genuinely engaged, not just names on a registration form.

Who Should Buy Organizer Lists?

Organizer lists still make sense if:

You're a title sponsor and the list is included in your package
You need 100% of registrants regardless of engagement level
The event is very small (under 100 people) and WhoGoes may not have coverage

Who Should Use WhoGoes?

WhoGoes is the better choice if you:

Attend multiple events per year and can't afford $5K+ per list
Want lists before or during the event for pre-event outreach
Need verified emails and LinkedIn proof of attendance
Want to access attendee data for events you didn't sponsor
