All Ideas

Standalone amenity access control software for HOA pools, gyms, clubhouses, and tennis courts — the product GateKeeper's competitors cannot match.

The Problem

Community pools, fitness centers, clubhouses, and tennis courts are the most-used amenities in residential communities — and access control for them is stuck in the 1990s. Most communities use physical key cards with no central management, paper sign-in sheets, or honor systems. When a property sells, nobody remembers to deactivate the old owner's pool fob. Non-residents sneak in. Capacity goes unmonitored. Liability exposure is enormous — if someone drowns at an overcrowded pool with no access log, the HOA board faces personal liability.

The Solution

A web-based amenity access management system. Each resident gets a digital credential (QR code, NFC tap, or linked to existing RFID fob) that works across all community amenities. The HOA admin dashboard shows real-time occupancy, access logs, and can instantly deactivate credentials when properties transfer. Capacity limits trigger automatic lockouts. Guest access is time-limited and trackable. Integrates with common access control hardware (HID, Brivo, Openpath) via API.

Portfolio Connection

This is the amenity access module from GateKeeper extracted as a standalone product. GateKeeper's product.json explicitly identifies "no amenity access control integration" as the gap every competitor has. PoolPass can be sold independently to communities that already have gate software but need amenity control — then upsell to full GateKeeper later. Sea Pines has pools, a fitness center, a clubhouse, and tennis courts that need exactly this.

Tech Stack

Next.js (App Router), Tailwind v4, shadcn/ui, Supabase (auth + DB + real-time for occupancy), QR code generation, NFC Web API, Stripe for billing, Vercel

Monetization

SaaS — $39/mo per amenity (1-3 amenities), $99/mo unlimited amenities, $199/mo for management companies (multi-community). Add-on: hardware integration consulting at $500/community setup fee. Target: 40 communities at $99/mo = $3,960/mo within 8 months.

Scoring Breakdown

DimensionScoreRationale
Feasibility9QR scan + CRUD + real-time occupancy, proven patterns
Monetization8Clear per-amenity SaaS, HOAs already budget for this
Market Value9Massive gap — no competitor offers this. First mover in HOA amenity access. GateKeeper upsell funnel adds strategic value.
Portfolio Synergy10Direct extraction from GateKeeper's #1 differentiator
Market Size8370K HOAs, most have pools/gyms. Amenity access is universal need.
Differentiation4**CORRECTED (Feb 20):** Access Granted Systems has sold "PoolPass" since 2014. Pool Entry, Proptia, Amenity Boss ($145/mo) all compete. At least 4 focused competitors plus modules in broader HOA platforms.
Build Time8~5 hours for core QR check-in + dashboard
