The Problem

Businesses and domain investors manage domains across multiple registrars (GoDaddy, Namecheap, Cloudflare). Each has different renewal dates and different reminder systems. Missing a renewal costs the domain — which could be worth thousands.

The Solution

Central dashboard to monitor all domains regardless of registrar. WHOIS-based expiry tracking with graduated email alerts at 90, 60, 30, and 7 days before expiry.

Target Audience

Domain investors, digital agencies managing client domains, and businesses with 10+ domains across multiple registrars who risk losing domains to accidental expiry

Why Now?

Domain aftermarket is booming — premium domains sell for six figures. Agency model means managing 50+ client domains is common. No simple, affordable cross-registrar monitoring exists.

Revenue Model

SaaS: $5/mo Starter (25 domains), $15/mo Pro (100 domains, SSL monitoring), $39/mo Agency (500 domains, API, client reports). Very low churn — set-and-forget tool.

Competitive Landscape

DomainTools

Enterprise WHOIS platform. $99/mo minimum, way too expensive for small portfolios

WhoisXML API

Raw API for WHOIS data. Requires custom development to build monitoring on top

Google Domains (now Squarespace)

Only monitors domains registered there. No cross-registrar monitoring
