Collect pre-launch leads: wishlisting/waitlisting for product launches

Many solo founders, indie-SaaS makers and small marketing teams struggle to convert pre-launch interest into paying customers because early-stage launch tooling is either too heavy or too generic; this problem affects an addressable base of roughly 10 million SMBs. Typical outcomes are low conversion from wishlists and waitlists—often single-digit percentages—and fragmented data across landing pages, email tools and product analytics, which makes prioritization and go-to-market planning difficult. You could build a lightweight, embeddable pre-launch platform that combines wishlisting/waitlisting widgets, no-code landing sections, automated drip and referral sequences, and AI-assisted copy and segmentation, offered as an annual SKU in the $99–$499 range. Core technical assets would be one-line SDKs and embeddable JS, pre-built integrations with Stripe and major email/product analytics providers, and models that score intent to enable targeted outreach. The market is attractive now: roughly $3.0B in addressable spend (10M SMBs × $300/year), a Market Score of 80/100 and Revenue Potential of 75/100 driven by the creator and indie-saas boom, broader no-code adoption and rising interest in AI-assisted growth. That said, competition is medium and success will require clear distribution channels or demonstrable conversion lifts to overcome switching costs. You can reasonably differentiate by focusing on measurable outcomes (targeting a 2–5x improvement in waitlist-to-customer conversion through personalization and triggered flows), minimizing time-to-value with embeddable components, and offering founder-friendly pricing and onboarding; the honest challenges are customer acquisition, proving ROI to skeptical buyers, and the ongoing maintenance burden of integrations and predictive models.
