FAQ
Common questions
Everything founders ask before running their first stress test.
What does Vonos actually do?
Vonos runs an adversarial 6-stage analysis on your startup idea. You submit the idea, target market, and competitors; we return a market reality map, an assumption autopsy with fragility scores, a premortem, an investor objection simulation, an opportunity map, and an executive go/no-go verdict.
Is the free preview really free?
Yes. Stage 1 (Market Reality Map) is free with no credit card. You only pay if you want the full 6-stage stress test report.
How much does the full report cost?
A single full stress test report is $99 (one-time). Pricing is shown in your local currency at checkout. There is no subscription.
How long does it take?
The free Stage 1 preview typically returns in under a minute. The full 6-stage report is generated asynchronously and usually arrives in 2–5 minutes.
Do I need to create an account?
No. Vonos is email-based — you enter your email when submitting an idea, and reports are delivered by email and via a private URL.
Will my idea be kept confidential?
Yes. Submissions are processed by AI providers solely to generate your report and are not used to train models. See our Privacy Policy for details.
Can I get a refund?
Refunds are available within 14 days for reports that have not been delivered or are materially defective, subject to Paddle's processing. Contact support@clouxart.com.
