Why do 43% of startups fail?

Tired of building products nobody wants? 43% of startups do! Let's flip the script! I'm a solopreneur, and I was always build the app before testing my business idea, which is a foolish thing to do. So, I created a new solution - www.testfa.st I realized I am wasting my time, so I built a business idea testing tool for myself, and now I am ready to share it with you too. So you too can create a landing page for yourself within 10 min or so. My tool asks some basic questions about the new idea, and based on the responses, it creates a landing page to help you test any business idea, with a newsletter subscription option. If anybody subscribes, they'll receive an email with a questionnaire for a 30% discount (if the product/service goes live), so we understand the audience better. Furthermore site is tracking number of visitors / subscribers count / questionnaire filling visitors so you can easily decide how much is the hype around your new idea as you get at least 100 visitors. Future versions will help you with marketing and acquiring potential customers. Would love your feedback pls. P.S.: The site speed is horrible, thank you for your patience! - It's still an MVP. Thanks, Zs
