Well organized and a great location. I love the cinema environment. Absolutely awesome! It felt like the whole organizing team really cared about every single attendee and speaker.

„ JCon offered a fantastic opportunity to meet people I had previously only known online, allowing for meaningful in-person connections. The event excelled in bringing together speakers from around the world, making it a truly global gathering. The impressive venue, featuring a large hall and a huge screen, added to the overall experience and created a captivating atmosphere. The positive energy and enthusiasm felt throughout the event made it a memorable and enjoyable experience. Based on these highlights, it would be highly beneficial to continue organizing JCon in the future.”

“Great venue with good seating. I really liked that there were multiple food options and a great assortment of cooled drinks available in the fridges. The speaker support was really good as well. Clear communication up front and good support from the people in the room. Everything just worked. Great to see.”

"I really liked the location with its high ceilings and a lot of natural light as well as good food options and a little park close by."

“The attendees! The vibe! The organizing staff! I was really blown away by the warm, thoughtful people I met and the great conversations I had. Not sure if there's a way to keep this around, other than I met a lot of great speakers so invite them back. I also appreciated that there were more women attendees than in some conferences I've been to. Thank you for a great event and all your care that you put into it.”

“The people. The audience was engaged with the talks, other speakers were great, crew was friendly and helpful. Thanks for having me!”

“The venue was magnificent! It was fun seeing old friends too.”

“I enjoyed the fact that is was not a commercial but community driven event. There were interesting speakers you don't find on other more international and commercial conferences”

“The organization, the shirts, and the food were great, with a wide selection; the beverages were everywhere at the gatherings and parties. And there were a lot of speakers. Overall, it was a great experience. I would love to join again”

“The location, the easiness of registration, the dinner, the friendliness and approachability of the organizers“

“The cinema location was great, the cinemas are great for the speakers and the huge screens are very nice for the audience. The free chilled drinks where also awesome. I liked that the JCON team tried immediately to fix all upcoming issues, everyone was very engaged to make it a good experience for everyone.”

JCON EUROPE was an incredible experience! The organization team was very friendly and helpful! I really like the aspect of a conference from the community for the community. The location, with its close proximity to the cinemas and exhibition areas, created a dynamic atmosphere for natural networking. Thanks for this great time!
