Specialized SaaS Idea Validation & Pre-Launch Waitlist Platform

The poster's specific need to validate a SaaS idea by building a landing page and collecting emails for a waitlist, combined with commenter insights on the importance of social proof ('X users joined') and the potential for stronger validation through pre-selling ('pay now and get 50-80% discount'), highlights a clear SaaS opportunity. A specialized platform tailored for SaaS idea validation and pre-launch audience building could be developed. This product would offer features beyond generic landing page builders, such as integrated A/B testing for value propositions, 'fake door' feature testing, robust waitlist management, easy implementation of social proof elements, and, critically, tools to manage pre-order campaigns with discounted early access and payment integrations. Such a focused SaaS solution could generate expected revenue starting from $140,000-$360,000 ARR with early adoption (200-500 users at an average $60/month subscription), scaling to $700,000-$1.8M ARR as it matures and attracts a larger base of 1,000-2,500 early-stage founders and indie hackers seeking to de-risk their ventures.
