Our Initiatives

CubStart

CubStart

We believe great ideas come from fresh and diverse mindsets, so we launched CubStart, a program for new hackers designed to make the hackathon experience feel less intimidating and more accessible for everyone!

Hackathon

Hackathon

Our mission is to empower others with technology to create solutions to better the world. Our annual hackathon, hosted at UC Berkeley's beautiful campus, is where the technology of the future is born. Join over 2200 students in coming together to create the world's next generation of groundbreaking innovations.

Fellowship

Fellowship

Why should we stop hacking after the hackathon is over? We shouldn't! Cal Hacks started the Cal Hacks Fellowship, a program that connects hackathon teams to the resources they need to grow their projects and take their visions to the next level.
