68 %

Name = Domain

This many of the 6,220 startups use exactly their name as the domain. Among the top companies of older batches it’s 91%.

8 characters

Median length

Half of all names are shorter. Only 9% have 13 characters or more, 1.8% a hyphen.

47 %

.com in the 2026 batch

In 2012 it was still 91%. The .ai extension now reaches 27%.

It turns your brief into a ready prompt for ChatGPT, Claude or Gemini. The AI uses it to generate 50 name candidates in five types, following rules that fit your industry.

Classic generators combine keywords with extensions. The result is lots of names with no connection to you. A prompt with a brief and rules delivers candidates that fit your project, audience and tone.

No. An AI can’t reliably know availability. Check your favourites with the registrar of your choice and trademarks in the relevant register (e.g. DPMA, EUIPO or USPTO).

The prompt builder is free and needs no sign-up. Your input stays in your browser; this page doesn’t store or transmit it. Only when you give the prompt to an AI tool does it end up there.

From an analysis of 6,220 startups that went through Y Combinator between 2005 and 2026: extensions, name lengths, additions and hyphens, split by industry. For local businesses and personal brands there is no comparable data, so rules of thumb apply there.

The quick filter gives you a rough sort. For the decision you need more: 15 criteria for brand, SEO, technology and legal. They are in Naming.
