[01] About
Capital Hacks is a collaborative initiative from the Carlsen Center for Innovation & Entrepreneurship and ACM Sac State. It brings together students with a passion for hacking, building, AI, and making an impact.
Pick one of four tracks and build a solution to a real-world problem. How you innovate is up to you: explore creative approaches and cutting-edge tools to bring your idea to life. On the final day, every team pitches to a panel of judges who score projects on innovation, applicability, technical proficiency, and potential impact.
New name, same hackathon. Hornet Hacks is now Capital Hacks. This is our fifth edition.
[02] Tracks
Choose the track that fits your idea. Each track winner takes home $500, and the best project overall wins the $1,500 grand prize.
Safer job sites, stronger infrastructure, and cleaner ways to build and power the places we live.
Better care, smoother clinical workflows, and tools that open doors for people of every ability.
We're in California's capital. Build tools that help government, public services, and communities work better.
