Executive Summary

Many neighborhoods and homeowners associations (HOAs) and their residents suffer from fragmented, noisy public marketplaces and ad-hoc community messaging that create trust and moderation problems; residents of 350K community associations and roughly 100M households lack a private, invite-only place to safely buy, sell, and coordinate locally. Property managers and volunteer boards also spend significant time fielding lost-and-found, resale questions, and enforcement issues that a centralized neighborhood tool could reduce. You could build a mobile-first, invite-only neighborhood marketplace with HOA-managed chat, built-in identity verification, moderation tools, simple payments, and optional integrations into existing HOA SaaS dashboards. The product would sell both B2B (HOA subscriptions, $1.5K ACV target) and B2C (low annual convenience fees or transaction revenue), plus optional premium listings and local services. This is timely: the estimated addressable market is roughly $6.5B (350K associations × $1.5K ACV plus 100M households × $60/year neighborhood commerce), and trends—HOAs buying SaaS, demand for closed communities, and higher expectations for trust and safety—score this concept 88/100 for market attractiveness with an 80/100 revenue potential. The space is medium-competitive, so go-to-market timing and partnerships matter. You can differentiate by focusing on deep HOA integration and admin workflows (making it a tool for managers, not just residents), robust identity/verification and moderation to build trust, and clear combined B2B/B2C monetization to improve unit economics. Be upfront that the main challenges are adoption inertia, moderation costs, and payment/regulatory friction; prove traction with pilot communities and measurable admin time savings before scaling.
