About the ChallengeThe#75HER Challenge Hackathonis part of CreateHER Fest's 75-day build journey culminating in anInternational Women's Day Celebration(March 8, 2026). This program focuses on creating technologywith and for women and marginalized communities—breaking patterns through thoughtful innovation.This isn't just about shipping "cool tech." It's about buildingproblem-framed, evidence-backed, responsible solutionsthat real people can use.Program Journey:Learn-a-thon → Idea-thon → Hackathon → Demo Day (March 8, 2026)Throughout the program, builders engage with mentors, peers, and guided resources designed to support learning, iteration, and responsible decision-making. Whether you're building your first prototype or refining existing skills, the goal is the same:choose a problem that matters, scope it realistically, and ship something you're proud to demo.Participation Expectations (Important)75HER is aparticipation-based challenge, not a submission-only event.
