At Encode, we were there with one goal in mind: to ensure a seamless experience for all. From overseeing the check-in process to fielding questions with a smile, we kept the wheels turning quietly in the background. Our aim was not to stand out, but to stand beside every attendee, providing the support needed to bring their ideas to life. It’s in these little moments that we found our contribution to the vibrant energy of the hackathon!

Doors opened at 13:30 and it was straight-up vibes — the place was packed with people ready to dive in! Check-in was buzzing, everyone getting their bracelets and gear, with a lot of “Hey, are you on a team yet?” going around. After everyone found their squad during the Team Formation, the Kick-off Event got the energy right. Hackers got down to business, bouncing between deep dives into code and hitting up the workshops to level up their game. First day of the ETH London Hackathon? Absolute win.
