Inspiration
Inspiration We wanted to show that AI agents can do more than chat — they can actually build a startup blueprint from scratch. JacHacks gave us the perfect excuse to prove that Jac's walker architecture is the right way to orchestrate multi-agent systems.
What it does You type a rough startup idea and Ken, our central AI orchestrator, activates 3 specialized agents (Idea, Market, Tech) that each perform deep analysis and compile everything into a complete startup blueprint. Each agent runs as a separate node in a Jac graph, producing real competitor research, market sizing, tech stack recommendations, and starter code.
How we built it We built the entire backend in Jac using Jaseci's walker pattern — Ken walks a graph of agent nodes, and each agent uses by llm() to replace function bodies with Claude. The frontend is a custom-designed website, and all agents connect to Claude Sonnet 4 through OpenRouter.
Challenges we ran into Learning Jac from scratch as freshmen while building under a 24-hour deadline was intense — debugging walker syntax and getting the AI integration working took real persistence. Getting the OpenRouter authentication and model routing configured correctly also made us waste some time.
Accomplishments that we're proud of We built a working multi-agent AI system in a language none of us knew 24 hours ago, and every agent produces genuinely useful, detailed output — not toy demos. The architecture is clean enough that adding a new agent takes 6 lines of code.
What we learned We learned Jac's graph-native programming model — nodes, edges, and walkers — and how by llm() lets you replace entire function implementations with AI using just a docstring. We also learned how multi-agent orchestration actually works under the hood, not just as a buzzword.
What's next for Kentroai Parallel agent execution with separate terminal windows streaming simultaneously, a downloadable desktop app, and idle completion, where agents keep refining the blueprint autonomously after you walk away. We also want to add more agents like Legal, Design, and Pitch Deck generation.
