CarCodeSMS is a startup that uses text messaging to connect customers with car salesmen, aiming to re-establish trust and make buying cars more comfortable. The company's novel idea caught the attention of Edmunds, who acquired them after they won a hackathon last year. Since then, CarCodeSMS has seen significant growth, expanding to 4,500 dealerships and increasing mobile leads by three times compared to desktop leads. The acquisition has also allowed Edmunds to drastically increase the value they bring to car dealerships.
