FAQs
What if I don’t have a product yet?
You don’t need one. This sprint is designed to validate the idea, not the tech. We'll test the problem, hook, and offer first so you can avoid building something nobody wants.
What if I’m still working full-time?
That’s who this sprint is built for. Everything is async and designed to fit in just 1–2 hours per day. No live calls. No public posts. No need to risk anything with your job.
Can I stay anonymous?
Yes. You never have to post publicly or reveal your name. All outreach and feedback collection can be done privately, and your idea stays under wraps.
Is the $297 refundable?
If you don’t walk away with clarity after 7 days, I’ll give you a full refund. No forms. No drama.
