CARG

Cargurus, Inc.

An online car-shopping marketplace that connects buyers with new and used listings from dealerships and private sellers across the US and dozens of other countries. Its "Deal Ratings" algorithm flags whether a price is a great deal, fair, or overpriced, so shoppers can compare without visiting lots. Founded in 2006 by Langley Steinert—the same person who co-founded TripAdvisor—it began as a community blog for car advice before growing into a full marketplace; the name nods to those early days when shoppers sought wisdom from car "gurus."
