QNST

Quinstreet, Inc.

A digital performance marketing company that connects people shopping for big-ticket items—insurance, credit cards, loans, home services—with brands that pay only when a lead or sale results. Founded in 1999 by Doug Valenti, a former Navy submarine officer and McKinsey consultant, QuinStreet grew by building and buying a network of research sites like Insurance.com and MoneyRates.com. The name blends the Latin "quin" (five) with "Street," evoking an online marketplace where buyers and sellers meet.
