TEDAI Vienna
Europe's official TED conference on Artificial Intelligence
The Challenge
TEDAI Vienna brings AI decision-makers, builders, and thinkers to the Hofburg palace for three days of signature TED Talks and discovery sessions. The challenge was reaching qualified attendees beyond TED's existing audience. Paid LinkedIn Ads were expensive for such a niche B2B audience, costing over €80 per registration, and generic social media campaigns struggled to convey the exclusivity of an application-only TED conference.
The Solution
TEDAI launched an Attendir campaign that enabled registered attendees to share personalized "I'm attending TEDAI Vienna" cards on LinkedIn. Each card featured the attendee's name overlaid on TEDAI branding, making every share a personal endorsement rather than a corporate advertisement. The cards appeared in the feeds of thousands of AI professionals across Europe.

ViennaUP
Europe's largest decentralized startup festival — 15,000+ participants from 90+ countries
The Challenge
ViennaUP is a city-wide festival spanning multiple venues and events across Vienna, with each event ticketed separately. The team needed a simple, frictionless way for participants to share their attendance across the many decentralized events — without adding complexity to an already sprawling festival format.
The Solution
ViennaUP integrated Attendir across their registration flow, enabling participants to create personalized visuals and share posts about the events they were attending. The quick setup was critical — given the decentralized nature of the festival, the tool needed to be intuitive for multiple event organizers to deploy independently.

"Before we started using Attendir, our team spent considerable time evaluating a range of content-sharing tools and weighing their features. None offered exactly what we needed: a simple, efficient solution that eliminated friction for event attendees who wanted to share about their participation."
"That's exactly what Attendir delivers, which is why we quickly became fans. The setup is not only quick and intuitive, but the tool also makes it exceptionally easy for participants to create personalized visuals and posts — significantly boosting the event's visibility."
"On top of that, the Attendir team is quick to respond and incredibly supportive. Overall, it's been a great experience, and we're excited to keep using it."
