Naming companies is so difficult. The number of constraints a name must satisfy only seems to grow each year. Between the dearth of available domain names, acceptability in other languages and international markets you might go into, it's surprising we don't have more names like Zzyzx.

Here are some resources to help with the process:

• Root words — It can be useful to combine these with a word or words relating to your business.
• Name generators: Wordoid, NameBoy.com
• Company name etymologies: Wikipedia List, Business Insider article
• Domain availability: Domai.nr, Lean Domain Search
