Auckland smart-trolley startup Imagr is seeking to raise US$25 million through a private investor pool to expand the business internationally.

Founder and chief executive William Chomley said demand had soared for the firm's autonomous checkout system after the Covid-19 pandemic.

He told Heather du Plessis-Allan Japanese retail chain H2O Retailing is Imagr's biggest customer using its smart shopping technology.

"They operate in the Osaka region in 152 supermarkets, we are already live in one of the supermarkets and hopefully can expand throughout the chain."
