Kelley Blue Book built its reputation on a promise: a number you could trust because the people giving it to you had no stake in whether you bought or sold. John Liss is betting that promise will travel from cars to houses.

Liss is the 33-year-old CEO of both True Footage, the appraisal-technology company he founded at 26, and its new joint venture with Cox Enterprises: Kelley Blue Book Homes, which launched nationally across 11 states on Aug. 3.

He was a real estate agent in high school. Fifteen years — and multiple Harvard degrees — later, he is persuading one of America’s most trusted consumer brands to put its name on a housing market where, by his own account, almost nobody trusts the numbers anymore.

“The available options are not accurate. They’re not interpretable. They’re not credible,” Liss told Fortune. “Consumers are starved for better tools to help make one of the biggest financial decisions of their life.”
