Square’s CEO, Jack Dorsey, explained on this week’s earnings call why he puts its subsidiary, Caviar, on a silver platter; Square’s payment-handling service is used by many restaurants, while Caviar’s food delivery-enabling platform allows those restaurants to reach a customer base eating at home; the key for Dorsey is cross-selling services that grow their customers’ businesses, even if the synergies aren’t apparent at first bite; on CNBC’s Squawk Box the day after the earnings call, CTO Sarah Friar said that Square has been “executing on all cylinders.” Source
