Plagued with growth issues, Quibi, a short-form mobile-native video platform, is shutting down, according to multiple reports. The startup, co-founded by Jeffrey Katzenberg and Meg Whitman, had raised nearly $2 billion in its lifetime as a private company. Quibi did not respond to requests for comment from TechCrunch. The company’s prolific fundraising efforts spanned prominent institutions in private equity, venture capital and Hollywood, all betting on Katzenberg’s ability to deliver another hit.
