Nice, invented business domain name which could be based on the Italian word "zanzero" (as in 'drinking companion').
Zanzeo has only six letters and only two syllables. Two-syllable names are highly rare and very desirable. Successful brands using two syllable names include Google, Kleenex and Starbucks.
This domain was first registered in April 2010. Older domains have an advantage when ranking in search engines.
