Schumpeter

A hands-on education solution that walks learners through the startup process step by step

Learners work through decks, from idea discovery to business model design, building up a business plan and pitch deck as they go. Instructors see every team's progress on a single screen.

  • Workflow: create project → practice with decks → generate deliverables
  • Team collaboration — teams edit the same project together
  • Progress monitoring for instructors and operators
  • Supports both camp-based and individual projects
