What Is .biz?
The .biz domain is a generic top-level domain introduced in 2001 as one of the first alternatives to the saturated .com namespace. Short for 'business,' it was specifically intended for commercial and business use.
While .biz never achieved the mainstream adoption of .com, it has maintained steady use — particularly for businesses that couldn't secure their preferred .com name. NameBio records over 2,600 aftermarket sales, with single-word industry-aligned names commanding $5,000–$15,000.
The extension is open to anyone without restrictions and has reasonable renewal costs. It's most commonly used by small to mid-size businesses and in specific industries where the .biz suffix carries a professional connotation.
Why This Matters for Startups
For most startups, .biz is not the first choice — .com, .io, or .ai will typically serve you better for credibility and recognition. However, .biz can work well as an affordable alternative when your preferred .com is taken and priced out of reach, especially for B2B businesses where the 'biz' association is natural.
