Choosing the Right Domain for Your Startup

Your domain affects first impressions, but not as much as founders think. Stripe was stripe.cc before stripe.com. Notion was notion.so. Instagram was instagr.am. The product matters more than the URL.

That said, a bad domain creates friction. Hyphens confuse people. Numbers require spelling out. Long URLs get mistyped. The goal is a name that travels well by word of mouth.

What Works for Tech Startups

Invented words dominate tech. Spotify, Twilio, Figma, Canva - none existed before their companies created them. Made-up names are easier to trademark, available in .com, and don't limit what you can become.

Action-based names work too. Zoom describes what it does. Slack suggests the opposite of work stress. Notion implies ideas. These names hint at function without being literal.

Common Naming Patterns

[Root] + suffix (-ify, -ly, -io): Spotify, Shopify, Bitly, Calendly. Suffixes make invented words feel natural. -ify suggests transformation. -ly implies action.

Compound words: Dropbox, Mailchimp, WordPress. Combine two real words into something new. Works when both words relate to your product.

Abstract short names: Uber, Lyft, Asana, Trello. Two syllables, easy to spell, no obvious meaning. Requires brand building but offers total ownership.

TLD Recommendations

.com remains the default if you can get it. Customers type it automatically. Investors don't question it. Email deliverability is best.

.io signals tech. Developers and investors recognize it. Many YC startups use .io successfully. Costs more but has better availability.

.ai makes sense specifically for AI/ML companies. If AI isn't core to your product, .ai might overpromise.

.co works as a .com alternative. Twitter used t.co. Short, professional, widely accepted.

Mistakes to Avoid

Don't use hyphens. startup-name.com forces you to say "startup dash name dot com" forever. Most word-of-mouth referrals will fail.

Don't use numbers unless they're part of your brand (37signals). Is it "5apps" or "fiveapps"? You'll lose half your traffic to the wrong version.

Don't choose a name similar to an existing company. Beyond trademark issues, you'll constantly be confused with them and may inherit their reputation.
