Event Fest is the largest event marketing festival in the Czech Republic and Slovakia, bringing together over 170 exhibitors and 3,400 attendees. It focuses on creating a shared space for event marketing professionals, agencies, and vendors who want to connect on industry trends and innovations. Now in its seventh edition, Event Fest combines an exhibition area with dozens of industry exhibitors, interactive zones, and workshops.
For their 2026 edition, the Event Fest team partnered with Walls.io to run an Echo campaign in the weeks leading up to the festival and a live social wall on site during the event.
We spoke with Jakub Klimeš, CEO of Liventa and Director of Event Fest, about how the combination of Echo and the social wall helped them scale their brand and energize their community.
Challenge: Event Fest has a lively community of participants, but traditional promotional methods were used in the past to encourage attendees to register and share their experience. Since the community was already engaged, the event would benefit from a more interactive form of “word-of-mouth” marketing that could turn their audience into active ambassadors who spread the word organically.
Solution: Instead of relying on traditional marketing methods, Event Fest used Echo pre-event marketing tool + a social wall displayed at the live event.
Results: Echo helped generate hundreds of organic shares before the doors opened. At the live event, 225 posts were collected on the social wall and there were approximately 2.4K visits to the wall.
“Echo gave people an easy and visually attractive way to publicly show they were attending. We embedded the sharing links across multiple touchpoints including registration confirmations, speaker communication, newsletters, social media and directly on the website, which helped generate hundreds of shares and consistent organic reach.”
How Event Fest used Walls.io:
In the month leading up to the event, attendees, speakers, and sponsors shared branded social media tiles across various social media networks by attendee, creating a viral chain
At the live event, a social wall was displayed on a large LED screen in the entrance hall, showing real-time posts, photos, and reactions as people arrived
3.2x viral boost (shares/clicks, meaning the event was 3 times more visible)

The interview
How did Echo help with promotion and building excitement before the event?
Echo helped us turn our audience into active ambassadors for Event Fest before the doors even opened. Instead of relying only on traditional promotion, we created a feeling that people were already part of the event experience weeks in advance. The campaign naturally encouraged attendees, partners and speakers to share their excitement online, which created authentic visibility and a strong sense of community around the festival.
The Echo campaign generated hundreds of shares. What do you think contributed to that success? How did you encourage people to spread the word?
What contributed most to the success was the combination of strong branding, emotional connection and simplicity. Event Fest already has a very engaged event marketing community, and Echo gave people an easy and visually attractive way to publicly show they were attending. We embedded the sharing links across multiple touchpoints including registration confirmations, speaker communication, newsletters, social media and directly on the website, which helped generate hundreds of shares and consistent organic reach.
Have you used a pre-event/word-of-mouth marketing tool in the past? What did Echo add to your pre-event marketing that you didn’t have before?
In the past, we used more traditional pre-event marketing tools focused mainly on paid campaigns, newsletters and static social media communication. Echo added something we were missing before: real audience participation before the event even started. It transformed promotion from one-way communication into something interactive and community driven, which felt much more natural and authentic for our audience.
Event Fest had very strong branding and visuals. How did Echo and the social wall help you scale the event’s brand?
Event Fest has always focused heavily on visual identity and creating a strong atmosphere around the brand, and Echo helped us scale that presence significantly online. Because attendees shared branded content themselves, the Event Fest visuals spread organically across LinkedIn and Instagram and created much stronger visibility than we could achieve alone.
“It felt less like advertising and more like people genuinely becoming part of the Event Fest story.”
On the live days, how was the social wall showcased at the venue, and what reactions or feedback did you observe from attendees?
During the live event day, the social wall became a major part of the atmosphere right from the entrance hall of the festival. We showcased it on a large LED social wall where attendees could see real-time posts, photos and reactions from the community as they arrived. People loved spotting their own content on the screen, taking photos of it and sharing it further online, which created another wave of engagement and energy throughout the entire event.
The analytics also showed strong engagement throughout the campaign period, with around 225 posts generated, over 1.7K interactions and approximately 2.4K visits to the wall. Most importantly, the sentiment was overwhelmingly positive, which confirmed that the audience genuinely connected with the campaign and the Event Fest brand.
Amplify your event’s reach before the doors even open
Event Fest’s experience shows what happens when you give an already engaged community an easy way to participate. By combining Echo’s pre-event sharing campaigns with a live social wall on site, the team turned promotion into a two-way conversation and extended the festival’s energy from weeks before the event right through the last session.
