School SharkTank is an engaging platform that transforms student entrepreneurship competitions into dynamic, gamified experiences. Designed for middle school, high school, and college environments, this app allows users to participate in pitch competitions hosted by their schools or organizations. Users can log in using phone, email, or SnapChat, select their school, and join competitions using a secure invitation code. Each competition hosts a set of student startup pitches. Participants, judges, and general users are allocated virtual currency—ranging from $100K to $1M—to invest in the ideas they believe in. As users invest in different pitches, the app ranks pitches based on investment totals, promoting real-time excitement and competition. The app also includes: - Role-based access (students, judges, coaches, admins)
 - Message boards for competitions and individual pitches
 - Photo sharing and moderated chat
 - Invite functionality for users outside the school (e.g., family and friends)
 - Investment dashboards showing user contributions and rankings
 - Pitch-specific profiles with videos, PDFs, and participant bios
 Administrators can manage users, assign roles, monitor activity, and suspend users or pitches when necessary. Coaches and judges are given additional currency and permissions to mentor and vote. Whether you're a student innovator, a teacher mentor, or a judge seeking the next big idea, School SharkTank brings the startup spirit to your school in a vibrant, secure, and educational environment.
