Jumio Inc., a venture-backed identity verification business whose customers include United Airlines Inc. and Airbnb Inc., filed for bankruptcy yesterday with a plan to sell itself to Facebook co-founder Eduardo Saverin, the Wall Street Journal reported today. The chapter 11 filing was authorized by the company’s board on Sunday, according to the resolution filed with the court. Saverin, who also is the main creditor of Jumio, is offering to acquire Jumio out of bankruptcy for $22.7 million, much of which is composed of debt forgiveness in addition to $3.2 million in cash. His bid would be subject to rival offers through a bankruptcy court auction process.
