10 courses · Coding + Maths + Science · Ages 8–18
Your child will build
what most adults can't.
Every course ends with Demo Day — your child presents what they built to 50+ people. Not a certificate. A standing ovation.
Make this the summer your child builds something real.
Three age-tiered cohorts. One unforgettable summer.
- AGES 8–10
Junior Builders
First code. First app. First Show Day. The summer they discover they can build.
- AGES 11–14
Builder Squad
Games, websites, AI, mobile. By Demo Day, a 14-project portfolio.
- AGES 13–16
Pro Builders
Real engineering. Live SaaS. Stripe payments. Industry judges at Demo Day.
Every Summer Season seat includes the full programme — live classes by the founder, Sandbox Studio, the Cohort Workspace, and a public Demo Day. Closes June 30.
Your child won't learn on a sandbox. They'll work in one.
Other academies teach on disposable Replit tabs. Sandbox Studio is our own platform — Git for code, real URLs for deploys, a moderated cohort where mentors live alongside them.
Real Deploys
Push code → live URL. Share with anyone.
Git Workflow
Branches, pull requests, code review.
Cohort Workspace
Moderated Discord with the mentor in every channel.
From first push to Demo Day.
Every stage carried by a real piece of our ecosystem — a live class, Sandbox Studio, the Cohort Workspace, the Demo Day stage.

The proven advantage of small-group learning
Bloom's 2 Sigma: A small-group student performs better than 98% of their peers.
Research from educational psychologist Benjamin Bloom showed that students who receive focused, small-group instruction achieve performance gains that are two standard deviations above students in traditional classroom settings.
Achievement Distribution for Students
At Own Sandbox, we bring this proven pedagogical principle to life:
Live small-group classes
Max 20 students. Same teacher for the full programme. Adapts to every child's pace.
Mastery-based progress
Students fully understand each concept before moving on. No rushing, no gaps.
Real-time feedback
Immediate support during every session. Questions answered, bugs debugged, confidence built.
