CogX is the UK’s largest technology festival and the largest AI festival outside of China. The festival of AI and Emerging Technology features a unique gathering of the leading figures shaping AI today. The team approached Marble LDN to design and produce the 2019 festival at 4 times the size of the 2018 event. This involved finding multiple spaces within the chosen central London venue to host up to 20,000 attendees over three days, and 687 speakers across 12 purpose built stages. The successful result took place during 10th – 12th June at a 67-acre area in Kings Cross. Opened by Mayor of London Sadiq Khan, the speaker line-up featured international Government Secretaries of State and business leaders from HSBC, IBM, Google, Unilever and more. We partnered with screenwriter Richard Curtis and his company Project Everyone to deliver the festival with the UN Sustainable Development Goals in mind.
