Our Story - Twelve Years of Hacking

Year after year, we bring together the brightest minds to inspire breakthroughs. Scroll through to explore our history!

I came in not knowing anyone and left with a new group of close friends. Easily the best part of the weekend.

I loved Cal Hacks from the finalist & judging format, the llamas, to all the people I met along the way it was a big highlight of my summer! Live, Laugh, Love Cal Hacks.

The thrill of building something new with tech I had never touched before and then seeing it win was an unforgettable experience. Cal Hacks pushed me out of my comfort zone and showed me what is possible when creativity meets collaboration.
