TreeLine Hacks was a fully virtual, 36-hour hackathon that brought together developers, designers, and innovators from around the world to build impactful projects from scratch. Taking place from March 6–8, 2026, the event challenged participants to go from idea to working prototype in just one weekend. Unlike traditional hackathons with rigid tracks, TreeLine Hacks was completely open-ended. Participants were encouraged to explore any problem space they were passionate about—whether that was AI, sustainability, fintech, education, accessibility, or entirely new and experimental ideas. The goal was simple: build something meaningful, creative, and technically impressive.
