Hank Asher

May 9, 1951 - January 11, 2013

Before the internet when his information business was just starting, DBT Onlline was just a PC and dial-up modem with access over a phone line, at that time  Hank only had local government records from Dade and Broward Counties.   In those early days we were among a small group of his first online customers and he was one of our South East Florida information sources.

In a few short years DBT Online grew into Database Technologies and was one of the largest online information database sources.

As large as his business grew, he was very active in its operation and would always take the time to talk on the phone and to give advise, often sharing interesting stories of his short career as a "low altitude tree-top pilot" when he smuggled drugs from Columbia and Belize to the Bahamas where he was living at the time,  Hank was never convicted of any smuggling crimes, but afterward he had a mysterious connection to the DEA and CIA as well as some of the most powerful people in politics - who later turned into his future financial investors.  

Hank was the founder of two more of the most successful information companies after Database Technologies:  Seisint and later TLFO (The Last F***ing One) which was later changed to the more politically correct "TLO" (now known as Trans Union TLO/XP.   

He was one of the pioneers in data fusion and data mining, his online database programming revolutionized how law enforcement and private investigators locate and research individuals and businesses.   


Hank unexpectedly lost his battle with cancer at the age of 61.
