Sales. The more you know about the people you're cold-calling, the better chance you have of selling them something. "Turning phone numbers into full profiles" is a primary objective of every telephone marketing/"lead-generation" campaign in the history of time, and automating part of it by aggregating publicly available data seems only natural. I would guess this is aimed less at telemarketers calling people's homes, and more at telemarketers selling business services (especially B2B startups), where cold-calling is seen as more legitimate and is the way a lot of business gets done. You want to know, at the very least, that you're calling someone whose job title indicates that they have the authority to spend money.
