G3 Hub complements what schools already do with guided, real-world missions that help students practice "how" — critical thinking, execution, and judgment — in ways that transfer to workplaces, innovations, and community impact.
Not a school. Not a curriculum replacement. Not credit-granting.
G3 Hub is a guided enrichment layer launched by Coble Studios that helps students practice real-world problem solving, reflection, and impact — without replacing school instruction. Our missions are derived from credible problem domains (e.g., TED, United Nations, Coble ecosystem) and curated into learning experiences that support judgment, execution, and clarity.
Not random client work
With mentor review
To nonprofits, businesses, enterprises
With optional spotlight features
Students engage with real-world problem domains through curated challenges that build thinking, collaboration, and execution.
Every mission includes guided reflection and mentor feedback to help students refine their thinking and solutions.
Students document their learning through short video journals. With consent, selected reflections are featured in our "G3 Summoning the Heroes" spotlight, emphasizing learning and impact — not comparison.
G3 Hub missions are crafted from real problem classes inspired by global institutions and the Coble ecosystem — not dependent on external companies to schedule or deliver projects.
