Your domain name is your first impression
Before anyone sees your product, reads your pitch, or tries your demo, they see your domain name. It's on your business card, in your email address, and in every link you ever share. A great domain name makes you look established from day one. A bad one makes people hesitate — and hesitation kills startups.
The good news: choosing a domain name isn't luck. It's a repeatable process. Here are 12 rules that actually work, drawn from watching thousands of founders name their companies.
1. Shorter beats longer, every time
Aim for under 15 characters before the dot. Short names are easier to type, easier to remember, and harder to misspell. If your name needs a hyphen or explanation when you say it out loud, keep brainstorming. Try a random word generator to spark short, punchy ideas.
2. Make it pass the "bar test"
Say your domain out loud in a noisy bar. If the other person can spell it without asking twice, you pass. Avoid tricky spellings, double letters, and words that sound like other words.
3. Brandable beats descriptive
Descriptive names tell people what you do but are forgettable and hard to trademark. Brandable names (Stripe, Linear, Notion) are unique, ownable, and grow with you. When in doubt, go brandable.
4. Check availability before you fall in love
Nothing hurts like naming your whole company around a domain that's taken. Check availability in bulk for every idea on your shortlist — including common misspellings — before you commit.
5. Get the .com if you can — but don't die for it
The .com is still the default people type. But a strong name on .io, .ai, or .co beats a weak name on .com every time. See our full TLD comparison to weigh price against perception.
6. Avoid hyphens and numbers
Hyphens get forgotten, numbers get confused ("five" or "5"?). There are rare exceptions, but as a rule: letters only.
7. Think about your email address
You'll say your email hundreds of times. Keep the domain short enough that "you@yourname.com" rolls off the tongue.
8. Check social handles too
Your domain is one piece of your identity. Before registering, check that matching handles exist on the platforms you care about. Consistent naming everywhere builds trust.
9. Avoid trends that expire
Names built on today's buzzwords age fast. Ask: will this name still make sense in five years? Timeless beats trendy.
10. Run a trademark sanity check
A quick search of your country's trademark database takes ten minutes and can save you a rebrand later. Skipping it is how founders end up with cease-and-desist letters.
11. Get five second opinions
Show your top three names to five people outside your team. Don't explain them — just ask which they'd click. The results will surprise you.
12. Decide fast, then move on
Founders waste weeks on naming. Give yourself a deadline: 48 hours, then register and build. A great product on a good name beats a perfect name with no product.

Staring at a blank page is the hardest part.

Frequently asked questions
How long should a domain name be?
Under 15 characters before the dot is ideal. Shorter names are easier to remember, type, and share.
Is .com still necessary in 2026?
It's the most trusted extension, but not mandatory. Many successful startups use .io, .ai, or .co. A strong brandable name on an alternative TLD outperforms a weak name on .com.
Should my domain match my company name exactly?
Ideally yes, but it's not required. Consistency across domain, socials, and branding matters more than an exact match.
Can I change my domain name later?
Yes, but it's painful: you lose SEO equity, break backlinks, and confuse customers. Worth 48 focused hours now instead of a rebrand later.
How do I check if a domain is available?
Use a bulk availability checker to test your whole shortlist at once, including plural and misspelled variants.
What makes a domain name "brandable"?
It's unique, easy to say and spell, emotionally neutral-to-positive, and doesn't box you into one product. Think Stripe, Figma, Vercel.
