Augmented reality firm Blippar, one of the UK's best-funded startups, is close to collapse. According to The Sunday Times, its chairman has written to shareholders warning of a dispute between two investors. Malaysian sovereign wealth fund Khazanah has reportedly blocked property tycoon Nick Candy from injecting further funding into Blippar. There have been months of red flags, with Blippar trying to sell itself earlier this year, internal dissatisfaction, and public accounts showing losses. Now, insolvency firm David Rubin and Partners has been lined up as administrators.
