The series lands in the Bay Area. A one-day, in-person hackathon for San Francisco's builders and tech community.
Powering the future of AI programming
Three hackathons, one language. Step into the projects, winners, and moments from every JacHacks so far.
170+ builders, 24 hours, one unforgettable weekend in Ann Arbor.
OPEN GALLERYStraight from the post-event surveys. What the room felt like, and what it felt like to ship on Jac for the very first time.
“JacHacks x Founders Inc brought the most ambitious minds in tech and put them under one roof. The event was ran extremely well and the hosts were very organized. If you want to code a basic project, this hackathon isn't for you. But if you're willing to push yourself, grow, and set your mind to shipping something in one afternoon, this comp is perfect for you.”
“The graph-based part and the walkers allowed us to come up with a really unique solution for finding multi drug synergies which I found interesting.”
“Building with the Jac stack and engaging with the community made JacHacks SF an incredible, hands-on experience!”
“I particularly liked the unified full-stack experience, graph-based programming model, and the byLLM keyword for native AI integration. Together, they reduced boilerplate, accelerated development, and made it easier to focus on building intelligent applications rather than managing multiple tools and frameworks.”
“Had a great experience overall. The hackathon was fun, collaborative, and a great opportunity to explore new technologies while building something meaningful.”
“It was really seamless, the agent understood the language and architecture much easily and wrote better more streamlined code overall.”
“I just like the different approach of byLLM instead of prompt engineering. It also meant having a more clean and understandable codebase which is a huge plus.”
“Great experience with my first large hackathon and had a great opportunity networking with recruiters and founders.”
“I liked how I could do everything in one language and didn't have to move between frameworks.”
“Wonderful time meeting all the different members of the Jac team and Jason as well. It was a fun and enriching experience.”
“The unified programming paradigm and the graph-based model make structuring full-stack AI workflows cleaner and more intuitive.”
“Graph-based programming also felt very natural for this problem. Since the system is inherently graph-structured, modeling it directly as nodes and edges made the logic easier to reason about.”
“It was a refreshing learning opportunity, and I enjoyed experimenting with Jac and actually a new way of thinking about software and AI development!”
“The one language end to end development was great because it made it really easy to build using the language and change ideas with the AI understanding everything it was doing from the start.”
“I really like the graph based memory and AI native design. Smooth interaction with other tech stack. Clean agent building.”
Before the series had a name, we took Jac and agentic AI on the road, sponsoring tracks and prizes at hackathons across the country.
