About CarGurus

CarGurus is one of the largest automotive marketplaces in the world, and the data we generate, what shoppers search for, how prices move, and how inventory turns across the country, is one of our most valuable and differentiated assets. We are investing in how we bring that data to our customers: turning it into products that customers can buy, license, and build on. It's a broad and fast-growing area for us, and we are increasingly embedding this data more deeply and robustly into the products and solutions we bring to market.
