Upstart co-founder and CEO David Girouard joins “Squawk Alley” ahead of the company’s IPO to discuss its business model. We are an AI lending platform, which means we apply AI to the problems of consumer lending. That means originating better loans because we can more accurately predict who’s more likely to default, says Girouard. That involves using all sorts of data so we can make a more informed decision, and one that can result in banks approving two to three times as many borrowers, he adds.
