Temporary self-deleting promo sites — simple paid ephemeral landing pages

Many SMBs, event organizers, micro-agencies and campaign teams need temporary landing pages for short promotions, event signups, product teasers and time-limited offers, but building, hosting and tearing them down creates friction, expense and leftover SEO/maintenance issues. This is a broad addressable problem — roughly 120 million SMBs worldwide, and at an assumed average spend of $100/year on ad/promo landing page tools, the market is on the order of $12.0B. Current options are either over-featured (full CMS/website builders), ad hoc (subdomains and manual deletes) or technical (developers pushing serverless deployments), which slows campaign cycles and increases cost. You could build a focused paid service that provisions single-purpose ephemeral landing pages with configurable TTLs, one-click templates, optional custom domains, analytics and integrations (payments, email, tracking), combined with serverless/Jamstack hosting for very low recurrent cost. Lightweight generative-AI assists could produce copy and imagery in under a minute, enabling per-site pricing or a low-cost subscription with predictable margins while keeping the UX deliberately simple. The timing is attractive: micro-SaaS buyers want single-purpose tools, serverless reduces hosting and lifecycle complexity, and AI shortens production time—factors reflected in a Market Score of 92/100 and Revenue Potential of 88/100 despite medium competition. Realistic challenges are customer acquisition cost, abuse prevention (spam/malware), and the legal/SEO implications of self-deleting URLs, so differentiation should emphasize an ironclad anti-abuse policy, enterprise-grade compliance options, frictionless templates and agency workflows; a sensible next step is to validate with 100 paying customers, aim for CAC under $40, and prioritize reliability over feature bloat.
