THE COMET NETWORK

Wi-Fi that gives up as soon as every machine connects
No plenary space for the kick-off, the pitches and the awards
A venue that closes while your format runs into the evening

On the day, you chase extension leads instead of hosting

Tell us about your hackathon (date, number of teams, duration) and receive an all-inclusive proposal in less than 24h.
Or come and visit one of our venues: it is even more telling.
A hackathon alternates team work and group moments: kick-off, check-ins, final pitches, prize-giving. The venue needs pods with a screen and power, breakout rooms and a plenary where you can switch formats in a few minutes.
Hundreds of devices connected at once: fibre Wi-Fi and on-site technical support stop anyone losing an hour to a network issue. Check the number of power sockets per workstation before the day too.
Natural light, lounge corners and regular breaks make the difference on an intensive format. For a few minutes in the open air, Comet Étoile and Comet Ternes have rooftops, Comet Place des Victoires a terrace, Comet Levallois and Comet Arboretum gardens.
Breakfast, breaks, lunch and dinner are crafted by Chef Vakhtang Meliava, with nearly 70% French produce. On a long format, meals follow your schedule, not the other way round.
Our venues are a few minutes from the metro in Paris, Brussels and Madrid: jury, mentors, students and external partners arrive easily, and our welcome team guides them on the day.
