Idea Twin questions
Is my Idea Twin a financial forecast?
No. The Idea Twin is a teaching toy that builds judgment about traffic, pricing, ads, and cash flow. Mechanics are simplified and stylized — validate with your store data and spreadsheets before spending real money.
How are the base-case projections calculated?
The twin reuses the Growthegy ecommerce simulator engine: your AOV, traffic, CAC, conversion, retention, margin, and cash seed an opening snapshot, then six phases run with no new initiatives on a fixed random seed. Same inputs always give the same projection.
How do I share my twin with a cofounder?
Use Copy share link in the builder. The link encodes your exact inputs, so opening it loads the same twin ready to inspect and play.
Can teachers use the Idea Twin in class?
Yes. Set a seed, then copy the class link (twin + seed). Every student who opens it plays the same twin with the same random events, so results are comparable in discussion.
What should I do after my twin validates?
Export the CSV, move your trusted assumptions into a spreadsheet for audit-ready modeling, then practice decision-making in the full ecommerce simulator before spending on ads or inventory.
