In September 2025 I organized Daydream Valencia, part of Hack Club's global Daydream weekend, and the first ever game jam in Spain for students under 18.
With around 70 teenagers present, we doubled Hack Club's original predictions, which they kept despite our warnings.
Dealing with this mismatch during the two days meant we needed to spin up extra Wi-Fi networks due to the number of devices, open an extra room to get more floor space, and other similar changes.
The catering budget we were given was only around 500€ for more than 70 people, but the team at AVAST kindly offered to cover the rest.
Together with this amazing contribution, their team also worked with us to promote the event around the city, as well as connect us with what would end up being our venue, Aula de Ciencia.
Yubico also acted as an event sponsor, giving us a big batch of Yubikeys to distribute to event participants. Thankfully they understood our attendance projection, so we had enough gifts for everyone.
I also want to thank specific people by name, because their contributions were the reason the event worked.
Mariel Navarro and Alex Negre's help was essential to fixing all issues we faced during the event and keeping it running smoothly, and Lisardo Fernández, AVAST vice-president, was the one who made sure everyone was able to have enough food and drinks for the entirety of the event, plus much more.
Despite the multiple issues we faced, we got a very positive NPS of 68/100 from 53 feedback submissions, and lots of interesting suggestions that we'll use to improve future events.
I might organize another competition in the future, but if I do it would be independent, with no global branding or organization, so that we can actually make the best event we can possibly think of.
