Build Night: 24-Hour Creator Tools Sprint
Brooklyn Navy Yard, Building 77
One night, one challenge, and a room full of mentors to help you ship it.
HOW IT WORKS
THREE WAYS TO SPEND THE NIGHT
Build solo
Just you and the challenge.
Grab a seat, pick up the challenge brief, and build on your own. Mentors rotate through the whole room, so you're never really alone.
Build with a team
Form one when you arrive.
Come with friends or meet your team at kickoff. Most teams are 2–4 people who met each other that night.
Mentor for the night
For students who've done this before.
Sat where they're sitting last year? Come back and help this year's room. Reach out through Contact to sign up.
From idea to shipped
- A junior built a tool overnight that auto-sorts club sign-up forms — her school still uses it.
- Two freshmen who'd never met before midnight shipped a shared study-timer app by sunrise.
- A senior turned her half-finished portfolio site into something she used in three college applications.

Why Attend
- High schoolers curious about building software, even with zero experience — we pair you with a mentor.
- Anyone who's started a project and gotten stuck. Bring the thing that's half-finished on your laptop right now.
- Students who want to meet other builders in their city. Half the point of the night is who you meet, not just what you ship.
