Sandbox — Real Projects. Real Builders. Real Growth.

Sandbox is a community and project marketplace where students and startups connect through real work.

Students can explore startup projects, apply to opportunities, save projects/posts/events, attend events, and build a profile that shows what they are actually interested in building. Startups can post roles, share updates, host events, review applications, and discover motivated student builders.

Sandbox fits into Social or Community and Marketplace. It works like a focused network for students and startups, while also acting as a project opportunity marketplace.

The problem

Students often learn skills through courses and tutorials, but struggle to get real experience or prove what they can do. Startups, on the other hand, often need help with design, development, research, content, and product work, but finding early talent through resumes alone is difficult.

Sandbox connects both sides.

How it solves it

Sandbox helps students turn learning into proof of work. Instead of just saying they have skills, students can show their activity, saved work, applications, interests, and projects.

For startups, it creates a simple way to find young builders who are already interested in working on real problems.

What makes it unique

Sandbox is not just a job board and not just a social feed. It is a build-in-public space where students, startups, and future founders can grow around real projects.

It is built around action, not just profiles.

How I built on the AI-generated base

I started with a Bubble AI-generated app as the foundation, then rebuilt and refined it into a more complete product. I improved the structure, cleaned the data model, fixed broken workflows, added student and startup flows, created hubs, profiles, explore sections, saved items, applications, projects, events, and demo data.

The AI gave me the starting point, but I shaped the final app through product thinking, UI/UX decisions, manual fixes, and better information architecture.

My submission(app i tried recreating Using Bubble) : App called Sandbox
