What makes a business name worth keeping?
A name worth keeping passes three filters: it is available across the domain, trademark, and state registry layers simultaneously. Many founders find a name they love only to discover it is taken at one of these layers - usually after they have already built a brand around it. The goal of a unique business name finder is to surface names that clear all three at once, not recycle options a dozen other companies have already tried.
The .com is still the most important single signal. A business that cannot get its exact .com name will spend years fighting the mental overhead of “no, it’s .co” or “no, it’s usebrandname.com”. Customers default to .com, email services default to .com, and press mentions often drop the extension. NameCraftr checks .com availability in real time for every suggestion, so you only see names that are actually available now.
Beyond availability, quality signals for a US business name are: it survives verbal communication (someone can hear it once and spell it correctly), it does not contain generic terms that are hard to trademark (Class 35 for business services, Class 42 for tech), and it leaves room for the business to expand beyond its first product or geography.
One test most founders skip: say the name as if you are leaving a voicemail for a prospect you have never met. Does it feel confident? Does the other person know how to find you online from that sentence alone? If you have to spell it or add context, the name is costing you money.
How to use the business name finder
Want more general options first? The business name generator might be a better fit, or if you’re set on “company” rather than “business”, try the company name creator.
Start with a specific brief, not a category label. “Payroll software for restaurants” produces more useful results than “HR software”. Include your target customer, the problem you solve, and one word that captures the tone you want - professional, playful, precise. The more specific the input, the more distinctive and legally defensible the output. This matters just as much for a small business name finder search as it does for a funded startup - a name grounded in your actual customer and neighborhood beats a generic word mashup every time.
Evaluate each suggestion against four checkpoints before moving forward:
- The verbal test. Read the name to a friend over the phone. If they ask you to spell it, note it and move on.
- NameCraftr’s real-time .com check. An available .com is your first green light, or run any shortlisted name through the standalone domain name checker to confirm. If the .com is taken, skip the name unless there is a compelling reason.
- Secretary of State business name search. Go to your state’s Secretary of State website (e.g., sos.ca.gov for California, sos.state.tx.us for Texas) and search for existing entity names. A name may have a clear .com but already be registered as an LLC or corporation in your state.
- USPTO trademark search. Search tmsearch.uspto.gov for marks in your class. Filter by “live” status and your goods/services class. An available .com plus a clear USPTO search means you can move forward.
Run two or three batches. Tighten the brief between each one - add what you liked and did not like about the previous suggestions. The third batch is almost always meaningfully better than the first.
After finding a name: making it yours
Once a name clears all four checks, execute this sequence before telling anyone the name publicly. Squatters watch registrar search traffic. The order matters.
Step 1 - Register the .com immediately. Use any reputable registrar (Namecheap, Google Domains, Cloudflare). Cost is $10-$15/year. Do not wait.
Step 2 - Register your business entity with your state. Go to your state Secretary of State’s website. The entity type determines the process: LLC formation (typically $50-$500 filing fee depending on state), Corporation formation, or a DBA (“doing business as”) / fictitious business name filing for sole proprietors or partnerships. Most states process online in 1-3 business days.
Step 3 - File a federal trademark with the USPTO. A TEAS Plus application costs $250 per class. File in Class 35 for business services or Class 42 for technology and software. Your rights date from the filing date, not the approval date - which takes 8-12 months. File early.
Step 4 - Claim social handles. LinkedIn, X, Instagram, and YouTube - even if you will not use them for 12 months. The cost is zero; the cost of losing them later is high.
One important distinction: state entity registration prevents another business in your state from using the exact same name, but it does not give you exclusive nationwide rights. Only a federal USPTO trademark does that.
Common mistakes when searching for a business name
Treating the domain check as the only clearance you need. An available .com does not mean the name is legally clear. Another business could hold a live USPTO trademark on that name in your industry, never have registered the .com, and still have standing to demand you stop using it.
Skipping the state business name database. This is the step most founders omit. Even if the .com is available and the USPTO is clear, another LLC in your state may already be registered under that name. This creates confusion for customers, banks, and potential legal complications before you have spent a dollar on marketing.
Registering the domain but delaying the trademark. Every day between registering the domain and filing the trademark is a window for a competitor to file first. Trademark rights in the US follow a first-to-file system for federal registration. File within 30 days of committing to a name.
Choosing a geographically or categorically narrow name. “Austin Roofing AI” is fine if you plan to stay in Austin and only do roofing. Otherwise, it is a constraint you will pay to rebrand away from. Names that work in your first market and in your fifth market are worth the extra creative effort.
Stopping after the first batch because nothing feels perfect. Rename your brief. Add the one adjective that captures your brand tone, specify your buyer more precisely, or explicitly exclude the types of names that are not working. The finder gets better as your input gets more specific.
