Just Submitted "Sandbox", a build in public platform for students, startups, and future founders.
Sandbox is not just a place where students apply to startup projects. It is a place where people document what they are building, find collaborators, post real opportunities, and turn learning into visible proof of work.
Check out my submission : https://on.contra.com/n8PqMh
The Problem:
Students are learning more than ever, but most of their progress stays invisible.
They complete courses, build small projects, watch tutorials, and improve their skills, but when it is time to get real opportunities, they are still judged by resumes, degrees, or experience they do not have yet.
Startups have the opposite problem.
They need motivated builders, but finding the right students or early collaborators is messy. Job boards feel too formal, social platforms feel too noisy, and most portfolios only show finished work, not the journey behind it.
There is a gap between learning, building, collaboration, and opportunity.
The Solution:
Sandbox is a platform built to close that gap.
It gives students a place to document what they are learning, share their projects, apply to startup opportunities, and build a visible proof of work over time.
It gives startups a place to document their journey, post real projects, review applications, discover student builders, and find people who are actually ready to contribute.
But the bigger idea is this:
Students should not only apply to startups. They should also be able to start something of their own.
That is why Sandbox allows students to post their own projects, find collaborators, build in public, and slowly move from learning to building to starting up.
Features:
Student and Startup Profiles: Every user gets a profile built around progress, work, and credibility. Students can show what they are learning and building. Startups can show their journey, projects, and current needs.
Project Discovery: Startups can post real projects with roles, skills, deadlines, and collaboration details. Students can discover opportunities that match their interests and apply directly.
Student Led Projects: Students can also post their own project ideas, find collaborators, and start building something before they ever become a startup.
Applications: Students can apply to projects, and startups can review applicants, view profiles, and manage project applications in one place.
Build in Public Posts: Students and startups can post updates, lessons, launches, milestones, and progress. The goal is to make work visible while it is happening, not only after it is finished.
Reposts and Upraises: Good ideas and useful updates can spread inside the community through reposts and upraises, helping active builders get discovered faster.
Leaderboards: The leaderboard highlights the most upraised posts of the week, giving visibility to strong ideas, valuable updates, and people who are consistently building.
Events: Students and startups can host events, workshops, demo days, collaboration calls, or learning sessions, making Sandbox feel like an active ecosystem instead of just a static project board.
How It Works:
Startups post real projects.
Students apply with their profile and proof of work.
Startups review applicants and discover motivated builders.
Students can also post their own ideas and find collaborators.
Both sides document progress through posts, reposts, events, and activity.
Over time, learning becomes proof. Projects become opportunities. Collaboration becomes a path toward starting up.
Built With:
Figma Make for the functional app prototype Figma Design for interface direction and refinement Supabase for backend
Why I Built It:
Sandbox comes from a simple belief:
Students need more than certificates. Startups need more than resumes. Future founders need more than an idea sitting alone.
Sandbox is a space for ambition, collaboration, and proof of work.
It is a small prototype right now, but the vision is bigger.
A place where students build proof, startups find builders, and future founders find their first collaborators.
Sandbox — Real projects. Real builders. Real growth.
