CogX - the UK's largest tech festival

CogX is the UK’s largest technology festival and the largest AI festival outside of China. The team wanted to build on the success of their previous two events, while expanding the size and capacity of the technology festival to attract the nationwide recognition it deserves.

Marble were tasked with designing and producing the entire festival, selecting the appropriate areas within Kings Cross to cater for 20,000 attendees (+400% increase on 2018) over three days, and big enough to host 687 speakers (+129% increase on 2018) across multiple stages (temporary or permanent). In addition, reflecting the Global Goals (UN SDGS) throughout the festival was a core part of the brief, and the main focal point for CogX partner Project Everyone.

CogX kicked off it’s third year at London’s Technology Week in June 2019 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, Ministers and business leaders from HSBC, Accenture, IBM, Alibaba, Google, Unilever, QuantumBlack and more. We partnered with screenwriter Richard Curtis and his company Project Everyone, which seeks to put the power of communications behind the UN Sustainable Development Goals (also known as the Global Goals).

The whole event was all designed by Marble, the only element not designed by us was the event content. This included the purpose built stages, interior design and all site-wide branding (directional, informational, site maps and bespoke branding for both CogX and the sponsors). The asset design comprised of a 120 page festival brochure, lanyards, t-shirts, water bottles and online assets. The technical design for the whole festival included all lighting and sound. Sponsor design included full production for: Google X, Accenture, AIG, 2030Vision, HSBC and QuantumBlack.

The main stage (the Impact Stage) hosted 750 guests over two floors, the Ethics Stage was a bespoke stretch tent structure with a tiered stage, built for purpose and rigged by Marble inside a Victorian gas holder by the canal, seating 500 guests. We took over the new Kings Cross tube tunnel that enters Granary Square and transformed the area with light effects, after poor weather conditions forced us to close the open air canal stage. Three stages were housed in the Tile Yard, a disused tile and meat packing warehouse, we worked with the owner to totally renovate the area in an eight week turnaround. They were built to bring sustainable materials to the forefront while engaging and enticing the audience to explore each new stage.

This was the first time anything like this had been held in central London and the administrative and security pressures was massive. We were also tasked with making sure that the surrounding restaurants and retail outlets were happy with the design and traffic plans.

By far our largest and most challenging project, which in turn made it an incredibly rewarding one! Just take a look at how well it was received below. Plus, we’re thrilled that our role in the project was recognised by C&IT magazine, and we won their ‘Technology and Telecoms Event of the Year” award!
