Datamining Cell Phone Databases

A couple of months ago an anonymous venture capital investor revealed one of his sources for soliciting investors – their cell phone database.

2. Age of cellphone number and time of first daily phone call

The age of an entrepreneur’s cellphone number reveals so much: their relative stability, how old they are, whether their number was a jettisoned friends-and-family program or an imported landline number. We get the age of cellphone number through a process called cellphone underwriting, which reveals all of the above and more, and which is perfectly legal but secretive enough that I won’t reveal how it works. At the end of the day, we’re looking for entrepreneurs who are young, stable, middle class, and who have the support of family and friends networks — and the age of the cellphone number tells us all those things.

 

So, I take the approximate age of a founder’s cellphone number and then during due diligence, I get a stat: The average time of their first phone call in the day. If you and your entrepreneur team are making and taking calls at 6:30 a.m PT, you’re probably talking with people back East and there’s a 50-50 shot you’re making north of a million in revenues.

 

So revealing data like this, that we used to W.A.G. (wild ass guess), we can now find out by using our firm’s make-shift cellphone underwriting API, which hooks in with Verizon and AT&T – the two main carriers of the iPhone. (And by “makeshift API,” I mean have our associate do it manually.)

 

I have some suspicions over the ability to do this, but there are certainly repositories of data out there.  You can read the rest here at GigaOm.
