StubHub was created in 2000 by Eric Baker and Jeff Fluhr, who were students of Stanford Business School and former investment bankers. In 2007, it was bought by eBay for $310 million. Viagogo, headed by StubHub's founder Eric Baker, purchased the company for $4.05 billion on February 13th, 2020 just before the COVID-19 pandemic stopped ticket sales.
