This domain is a play on "Sense" and "AV", which could signify Aviation, Audio-Visual, or Anti-Virus, among others.
Sensav has only six letters and only two syllables. Two-syllable names are extremely rare and very prestigious. Successful brands using two syllable names include Pepsi, Subway and Twitter.
This domain was first registered in September 2016. Older domains have an advantage when ranking in search engines.
