Who can participate?

Builders from LATAM, living in LATAM—developers, designers, PMs, and founders. You can join solo or with a team (teams must be at least 50% LATAM).

Do I need a team?

No. You can apply solo and team up during kickoff, or you can bring a team. Solo projects are welcome too.

Can I apply to more than one track?

Yes — builders can apply to as many tracks as they want. Pick what fits your project (or multiple, if relevant).

What do I need to submit?

A Karma Gap link to your project. Inside your Karma Gap project profile include: live demo link, GitHub repo link, slides, and a demo video.

What are the judging criteria?

Impact, execution quality, clarity of the demo, and craft. Bonus points for shipping end-to-end and telling a great story.

How do submissions work?

Submit via a form with your Karma Gap project link. Your Karma Gap project should include your GitHub repo, deck, and demo.

How does dark mode work here?

This site uses next-themes. The theme toggle sets a class on <html> (dark/light/system) and Tailwind styles follow it.
