A one-day AI Innovation Sprint to build with AI, test with people, and leave with a working prototype.
Teams of at least 2 · Solo applications welcome 999

Vibe coding is a way to build software by describing what you want in natural language. AI can generate the interface and logic, while you guide, test, and refine the result based on real user feedback.
Isolate who struggles with the problem and define the single riskiest assumption worth testing before building further.
Turn your concept into interactive screens and working application flows through plain-language prompting and fast iteration.
Put your prototype in front of experts and potential users to get real feedback.
Demonstrate your working prototype on stage, gather audience feedback, and leave with clear evidence for your next iteration.
Two Building Directions: choose where to focus your build.
Bring whatever idea you want to explore: a personal tool you have always wanted, a creative experiment, a daily workflow shortcut, or a startup concept. You have complete creative freedom. The directions below are examples for inspiration, not set themes.
Example directions (not fixed themes):
This track is for participants who would like to build something useful for Riga residents or visitors. You are free to tackle any challenge or local opportunity you care about. The areas below are illustrative examples to spark ideas, not mandatory themes or official challenges.
Example areas for inspiration:
The Riga Vibe civic track is optional. Bring your own idea, or explore a project that benefits Riga.
We believe that project development works best when domain insight pairs with agile building, so every project is developed by small multidisciplinary teams.
