YC Insights

What Makes a Name YC-Worthy?

We analyzed naming patterns across 5,000+ YC companies to understand what works. The pattern is clear: the best YC startup names share specific characteristics that signal quality and ambition.

Think Stripe, Airbnb, Dropbox, Coinbase, Figma. These aren't descriptive names - they're brandable, memorable, and built to scale. None of them tell you exactly what the product does, yet they've become synonymous with their categories.

The trend continues in recent batches. .AI domains dominated YC W25, with 28% of companies choosing this extension. The message is clear: your domain signals your ambition and market focus.

Stripe, Notion, Linear

Short, abstract, instantly memorable. These names work globally and don't limit product expansion.

Vercel, Retool, Amplitude

Invented words that sound professional and suggest capability without being literal.

getEmailFast-app.io

Descriptive, forgettable, hard to spell. Signals you couldn't secure a proper domain.

Frequently Asked Questions

What naming patterns do successful YC startups follow?

Successful YC startups typically use short, memorable names (1-2 syllables) that are easy to spell and pronounce. They avoid descriptive names that limit growth, preferring abstract or invented words that can scale with the company.

How do I choose between .AI, .IO, and .COM for my YC startup?

Match your extension to your market: .AI signals AI/ML focus and is trending among YC batches, .IO is popular for developer tools and B2B SaaS, while .COM remains the gold standard for consumer products.

Should my startup name describe what we do?

Generally, no. Descriptive names like 'FastEmailApp' limit your ability to pivot or expand. The most successful YC companies use abstract names that don't directly describe their product but become synonymous with their category.

Can I finance my domain purchase?

Yes, we offer flexible payment options for premium domains. This allows pre-funding startups to secure ideal names without impacting runway. Contact us for installment plan details.
