#3. Snoball — Best Managed Attendee Advocacy Service

The only advocacy provider with published benchmark data (31.9% share-to-registration conversion), offering fully managed campaigns with a dedicated campaign manager. Enterprise-only pricing.

Snoball takes a managed services approach to attendee advocacy.

#5. Premagic — Best for Photo-Based Event Advocacy

AI-powered photo enhancement and post-event sharing galleries at the lowest price point in the category. Won Event Tech Awards 2025, but serves a different use case than pre-event advocacy platforms.

Premagic focuses on post-event photo sharing and branded galleries rather than pre-event attendee advocacy. Their AI automatically enhances event photos and enables attendees to find photos of themselves using facial recognition. While this generates post-event social sharing, it does not directly drive new registrations the way pre-event advocacy tools do.

Pricing: From $99/month (basic plan). Higher tiers for larger events. Limited free plan available.

  • Cheapest option in the category ($99/month)
  • AI photo enhancement and facial recognition
  • Award-winning (Event Tech Awards 2025)
  • Post-event only — does not drive pre-event registrations
  • Limited LinkedIn-specific advocacy features
  • Different use case than attendee advocacy (photo sharing vs. registration driving)

Best for: Event organizers who want branded post-event photo galleries and social sharing of event memories. Works well as a complement to a pre-event advocacy tool like Attendir or Gleanin.

How We Evaluated

We evaluated each platform across six criteria: channel breadth (number of supported sharing channels), campaign types (attendee, speaker, sponsor, exhibitor support), analytics depth (cross-channel attribution, per-advocate tracking), enterprise readiness (SSO, API access, team management), track record (years in market, client base, published data), and ease of adoption (self-serve access, setup speed, pricing transparency).

Gleanin ranks #1 for overall attendee advocacy because of its unmatched channel breadth and decade-long enterprise track record. Attendir ranks #2 as the best self-serve option — ideal for teams that value speed, transparency, and LinkedIn-focused results over multi-channel complexity.

Frequently Asked Questions

What is attendee advocacy?
Attendee advocacy is a peer-to-peer event marketing strategy where registered attendees promote an event through their personal social media networks — primarily LinkedIn — driving organic registrations through trusted peer recommendations rather than paid advertising. It works by providing attendees with branded sharing assets and a frictionless one-click sharing experience. According to Snoball's benchmark report, attendee advocacy campaigns achieve a 31.9% share-to-registration conversion rate. Learn more: attendee advocacy explained.
Which attendee advocacy platform is best for small events?
For small events (under 500 attendees), Attendir is the best fit. It starts at €390/month with self-serve setup in under 5 minutes, no onboarding calls, and no annual commitment. Premagic is cheaper at $99/month but focuses on post-event photo sharing, not pre-event advocacy. Gleanin starts at $459/month but requires annual billing ($5,508 minimum commitment) and an onboarding session. Snoball and InGo are enterprise-only and impractical for small events.
Do attendee advocacy platforms integrate with Eventbrite?
Attendir has a native Eventbrite integration that automatically imports events and triggers sharing invitations when new attendees register. It also integrates natively with Luma, Cvent, and Bizzabo. Gleanin does not offer native ticketing integrations — you would need to use Zapier or manual CSV imports. Snoball and InGo handle integrations as part of their managed service setup.
What ROI can I expect from attendee advocacy?
Industry benchmarks show attendee advocacy drives registrations at €2–5 per registration compared to €25–50 for LinkedIn Ads. Snoball's published data shows a 31.9% share-to-registration conversion rate. A typical campaign: 200 attendees × 25% share rate = 50 shares × 500 average LinkedIn connections = 25,000 impressions × 1.5% click rate = 375 landing page visits × 31.9% conversion = ~120 new registrations. At a €200 ticket price, that is €24,000 in revenue.
Is attendee advocacy better than influencer marketing for events?
For B2B events, attendee advocacy typically outperforms influencer marketing. Peer recommendations convert at 3–5x higher rates than influencer posts because the audience trusts personal connections more than paid endorsements. Attendee advocacy also costs significantly less — €2–5 per registration vs. €50–500 per influencer post. Influencer marketing works better for consumer events or brand awareness, while attendee advocacy delivers more measurable, cost-effective results for professional events.
Which attendee advocacy platform has the best analytics?
Gleanin offers the most comprehensive analytics with cross-channel attribution, conversion tracking, and enterprise reporting dashboards (available on their Pro plan at $1,539/month). Attendir provides per-advocate tracking with unique sharing URLs, real-time impression and click data, and conversion attribution — included in all plans. Snoball provides detailed campaign reports as part of their managed service. InGo offers LinkedIn-specific social graph analytics.
