Tips for Picking Your Idea
Match the theme. Always align your project with the hackathon theme and tracks. Projects that fit specific prize categories have a better chance of winning.
Start with the demo. Think about what your demo will look like before you start building. Work backwards from a compelling 2-minute presentation.
Use available APIs. Many hackathons have sponsor APIs and tools. Using them shows engagement and often qualifies you for sponsor prizes.
Keep scope small. A polished, working prototype always beats an ambitious but broken project. You can always add features after the hackathon.
