Combine knowledge sharing with festival experience through seven principles. Keep presentations and workshops short. No two-hour lectures, but sessions of 45 to 60 minutes. Follow each session with networking time or a break. Mix formats: alongside presentations, also demonstrations, workshops, panel discussions and posters. Build in physical beauty: a beautiful venue, inspiring décor and good design. Attendees remember the feeling better than the facts. Integrate social moments: drinks receptions, group dinners and informal meeting spaces. Work with game elements where relevant: badges, challenges and leaderboards. Put the emphasis on community: this is the place where like-minded people come together. Offer flexibility: attendees choose their own sessions. Live Impact designs that balance.
