You want a short startup name. Three to five letters, ideally. Something that fits on a favicon and doesn't require a spelling lesson on a podcast.
Then you check the domain. Taken. Parked since 2003. Listed for $48,000 on a marketplace you've never heard of. The search for short startup names feels like walking through a stadium after the game, picking through empty seats.
The good news: short brand names are still out there. You just need a different search strategy than typing into a registrar and hoping.
Why Short Startup Names Feel Impossible
The .com namespace has been open for commercial registrations since 1985. Every two-letter, three-letter, and four-letter combination under .com was claimed years ago. Most five-letter .com domains are registered too.
But that scarcity applies to dictionary words and random letter strings. It does not apply to the full universe of pronounceable, brandable combinations.
The domain aftermarket is not the same as the domain namespace. Many short names are registered but unused, parked, or owned by small holders willing to sell for a few hundred dollars, not five figures.
The real constraint isn't availability. It's your search method.
Where to Actually Look for Short Brand Names
1. Expired and Dropped Domain Lists
Every day, thousands of domains expire and return to the pool. Some of them are short, pronounceable, and perfectly usable.
Tools like ExpiredDomains.net let you filter by length, TLD, and character pattern. You can search for five-letter .com domains with no hyphens, no digits, and a specific consonant-vowel structure.
The catch: you need to act fast. Good dropped domains get picked up within hours, sometimes minutes. Set up alerts and check daily.
2. Brandable Marketplaces
Several marketplaces specialize in invented, pronounceable names rather than keyword domains. These are short brand names that were created specifically for startups.
- BrandBucket lists curated names with logos, usually in the $2,000 to $5,000 range.
- Squadhelp runs naming contests and also sells pre-made brandable domains.
- Brandpa focuses on shorter, modern-sounding names.
These marketplaces do the filtering for you. The names are already vetted for pronounceability, trademark risk, and brand feel. You pay a premium for that curation, but it's often cheaper than hiring a naming agency.
3. Trademark Databases
Before you fall in love with a name, check the USPTO database. A short name that's available as a domain might still be trademarked in your category.
This works in reverse too. Searching trademark databases can surface interesting word fragments and combinations that never became famous brands. Those abandoned marks can inspire original 5 letter startup names.
4. Word Fragment and Morpheme Mining
Instead of searching for complete words, search for fragments. Take a prefix like kin, lum, vex, or nori and combine it with a suffix like a, o, ly, or ix.
This is how many modern short brand names were built:
Stripecame from a simple object, not a fragment, but the principle holds.Notion,Linear,Vercel, andRampall use real words with a slight semantic tilt.
You can automate this. Write a script that combines a list of prefixes and suffixes, then checks availability in bulk.
for prefix in kin lum vex nori cal bri; do
for suffix in a o ly ix io; do
domain="${prefix}${suffix}.com"
whois "$domain" | grep -q "No match" && echo "AVAILABLE: $domain"
done
done
This approach generates hundreds of candidates in seconds. Most will be nonsense. A few will click.
5. Non-.com TLDs
The .com bias is real, but it's not absolute. Plenty of successful startups launched on .io, .co, .ai, or .so before upgrading to .com later.
If you're building a developer tool, .io and .dev are accepted. If you're in AI, .ai is now mainstream. A short name like ray.ai or crew.co works because the TLD reinforces the category.
The tradeoff is credibility with non-technical audiences. A .io domain can confuse a customer who expects .com. Weigh that against the cost of a five-figure .com purchase.
The Tradeoff Matrix
Here's a realistic comparison of where to find short startup names, what you'll pay, and what you're actually getting:
| Source | Typical Price | Availability | Brand Quality | Speed |
|---|---|---|---|---|
| Hand-registration | $10–15/year | Very low for 4–5 letter .com | Unpredictable | Instant |
| Expired domains | $10–100 | Moderate, daily drops | Mixed, needs filtering | Hours to days |
| Brandable marketplaces | $1,500–$6,000 | High for curated names | High, pre-vetted | Days |
| Domain aftermarket (Sedo, Afternic) | $500–$50,000+ | Depends on budget | High for good names | Days to weeks |
| Naming agency | $10,000–$50,000 | Custom | Highest, with strategy | Weeks to months |
The table makes one thing clear: you're trading money for time and quality. Hand-registration is cheap but mostly picked over. Marketplaces cost more but save you weeks of searching.
How to Evaluate a Short Name Before You Commit
Shortness is not the same as goodness. A five-letter name that's hard to pronounce or spell creates friction forever.
Run every candidate through this checklist:
- Say it out loud. If you have to explain the pronunciation, it fails.
- Type it on a phone. Autocorrect should not fight you.
- Check the obvious social handles. Twitter, Instagram, LinkedIn, GitHub.
- Search the name. If another company uses it in a different category, that's a flag, not a dealbreaker.
- Check trademark class. Your category is what matters, not all categories.
A short name that's available as a domain but already trademarked in your category is a lawsuit waiting to happen. Domain availability is not trademark clearance.
The Case for Buying Instead of Inventing
There's a quiet trend among solo founders: buying a short brand name outright instead of spending weeks generating candidates.
The logic is simple. If your time is worth $100 per hour and you spend 30 hours searching for a hand-registered name, you've spent $3,000 in opportunity cost. A marketplace name at $2,500 is cheaper.
That math doesn't work for everyone. If you're bootstrapping with no revenue, $2,500 is real money. But if you've raised a pre-seed round or have consulting income, buying a vetted name is often the rational choice.
FAQ
Why are all the short startup names taken?
The .com namespace has been open since 1985. Every two, three, and four-letter combination was registered long ago. Most five-letter combinations are also taken, especially pronounceable ones. But many of those registrations are parked, unused, or owned by small holders willing to sell. The constraint is discoverability, not absolute scarcity.
How much should I pay for a 5 letter startup name?
It depends on the source. Hand-registered names cost $10 to $15 per year if you find one available. Expired domains typically cost $10 to $100 at auction. Brandable marketplaces list names between $1,500 and $6,000. The domain aftermarket can range from $500 to $50,000 or more for premium names. Set a budget before you start looking.
Is a .io or .co domain okay for a startup?
Yes, for certain audiences. Developer tools, AI products, and crypto projects commonly use .io, .ai, and .co. These TLDs are accepted in those communities. For consumer products targeting non-technical users, .com still carries more trust. Some startups launch on an alternative TLD and buy the .com later when revenue justifies it.
How do I check if a short name is trademarked?
Search the USPTO database at uspto.gov for your name and category. Also check the EUIPO database if you plan to operate in Europe. A domain being available does not mean the name is legally clear. Trademark conflicts are category-specific, so a name used by a company in a different industry may not block you.
Can I automate the search for short brand names?
Yes. You can write a script that generates candidate names from prefix and suffix lists, then checks domain availability in bulk using the whois command or a registrar API. Tools like ExpiredDomains.net also let you filter dropped domains by length, pattern, and TLD. Automation generates hundreds of candidates quickly, but you'll still need human judgment to pick the good ones.
