Fixed Supply, Growing Demand
There are a finite number of 4-character .com domains. Every combination of letters and numbers that exists, exists — and no new ones can be created. As the internet grows and more brands need a web presence, demand for short domains increases against supply that never changes.
.com Still Dominates Trust
Despite decades of alternative TLDs (.io, .co, .app, .ai), .com remains the default expectation. Customers type .com by instinct. Email sent from a .com domain arrives with authority that newer extensions don't carry. For a brand that wants to be taken seriously, .com is still the only answer.
Versatility Commands a Premium
A short domain like RD40 works for nearly any industry. Tech startup, consulting firm, product brand, media company, sports team — the brevity and neutrality make it adaptable. Versatile domains attract more buyers, which supports stronger pricing.
The Branding Advantage
Short domains reduce friction everywhere: business cards, verbal directions, social handles, app store listings, email addresses. Every character removed from a domain reduces the chance of a typo and increases memorability. Brands that invest in short domains see the benefit across every channel.
