In 2010, over a sushi dinner with a friend, Jason sparked an interest in what would become his next entrepreneurial adventure: transforming modern card issuing. With a deep intellectual curiosity for how credit cards work, Jason built Marqeta to bring game-changing card products into the world. Marqeta now works with customers in 39 countries, has a team of nearly 900 employees, and IPOed in 2021. Jason shares how he almost moved to Australia to start a Jamba Juice-style chain before Marqeta, how he persevered after nearly running out of money in 2015, and why he's fueled by the challenge of people not believing in him.
