"Our integration with Marriott International ( MAR ) was substantially delayed due to unexpected challenges in aligning our technology frameworks, resulting in significant, unanticipated integration costs, as well as a sharp decline in revenue," Sonder ( SOND ) said Monday in a statement.

Sonder ( SOND ) "ultimately was unable to execute a viable going concern transaction for its business and operations or obtain additional liquidity," according to the statement.
