Frequently Asked Questions
Straight answers before you spend a minute or a dollar.
What is a startup simulator?
A startup simulator tests a business idea against realistic market data — traffic limits, conversion rates, churn, and monthly burn — compressed into a 180-day timeline. Goodbye Startup runs that simulation with an AI mentor instead of a spreadsheet.
How does Goodbye Startup work?
You describe your idea and your real starting position (capital, team, monthly burn). The AI mentor then walks you through five phases: market reality check, product launch, user behavior simulation, the day-180 financial crunch, and a final lessons report.
Is Goodbye Startup free?
Your first full 180-day simulation is free and requires no credit card. Unlimited simulations cost $9.99/month, or a one-time $49.99 lifetime pass.
What data does the simulation use?
Industry-median and deliberately pessimistic benchmarks: cold-start click-through rates of 0.5–2%, website-to-signup conversion of 1–3%, free-to-paid conversion of 0.5–2%, and monthly churn of 10–20% for early-stage products.
Do I need to quit my job to test my idea?
No. The simulator exists so you can test the idea before quitting. It shows whether your savings and runway would survive realistic customer-acquisition costs.
Who is Goodbye Startup for?
Aspiring founders — especially solo developers and first-time entrepreneurs targeting the US market — who have an idea but want hard evidence before risking their savings or a steady salary.
How long does one simulation take?
About 15–30 minutes of conversation, covering 180 simulated days across five phases and key decision points.
