Fintech firm NerdWallet made its IPO debut on the Nasdaq on Thursday. CEO Tim Chen joined Cheddar to talk about the decision to tap the capital markets now and explained the company's revenue model by taking a cut from financial products like credit cards and loans sold through the site. Chen also talked about the firm's stance on cryptocurrencies, noting it advises people to only invest what they can afford to lose. (Updated November 5, 2021 to reflect that NerdWallet went public on Nasdaq, not NYSE.)
