Every domain investor has a tell. The INTJ hunts single-word .coms like chess pieces — three moves ahead, never blinking. The ENFP falls in love with a name on Tuesday and owns it by Thursday. The ESTP buys before the call ends. Your portfolio isn’t a collection. It’s a personality test you didn’t know you were taking.

So I built the test on purpose. The Domain Type Index is a four-question quiz that reveals your domain-buying alter ego across 16 personalities — then shows you your Domain DNA: five stats describing how you actually buy. .com Loyalty. Brandability. Speculation. Literal Naming. Weird TLD Tolerance. An ENTP runs 42% .com loyalty and 96% weird-TLD tolerance. An ISTJ is the mirror image, and proud of it.

16 Personality types profiled — each with its own buying stats, hunting style, blind spot, and signature move.

The quiz is the doorway. Behind it sits a name generator that builds a 12-name shortlist matched to your type, with live availability checks and one-tap registration links. Duo mode blends two types for co-founders — because an INTJ × ENFP partnership is either a venture fund or a crime spree, and the names should know which.

Then there’s the Playground, which is where the thing gets dangerous. Type Detective: a daily game — three mystery domains, one owner, name their type, keep your streak alive. Portfolio DNA: paste your portfolio and we read its soul — brandable-addiction percentage, AI-hype exposure, speculation index, and a one-line diagnosis. (The ENFP report reads “your portfolio is a mood board with renewal fees,” and I felt seen.) Domain Roast: pick any domain and any of the 16 types will tell you exactly what’s wrong with it. Head-to-Head: two names enter, and all 16 personalities vote on the winner.

The move Take the quiz, then generate names for your type. Knowing your buying personality is an edge: you stop fighting your instincts and start pricing them. The INTJ who knows he’s an INTJ stops apologizing for the spreadsheet.
48 Hand-written roast lines in the Playground — three per personality type, zero mercy.

Strictly unscientific. Wildly accurate. That’s the whole pitch — and the reason it works. Naming is taste, taste is personality, and almost nobody in this business has ever examined theirs. The investors who know their type buy with conviction. The ones who don’t just have renewal bills.
