Robinhood was launched last year amid surging demand for food delivery due to COVID-19 related lockdowns and now boasts around 2.3 million users and 26,000 riders who handle over 150,000 orders a day.

"Next year will be a year of travel ... Food is a loss leader, but it is building our customer base. This is why we have to be a super-app," said Thana Thienachariya, chairman of Purple Ventures, a subsidiary of SCB, the country's fourth largest lender.

Competition in Thailand's food delivery market intensified this year after Malaysia's AirAsia bought Indonesia's GoJek's business in Thailand and e-commerce platform Shopee, owned by Singapore's Sea Ltd, rolled out a local food delivery service.

By 2023, Purple Ventures will have invested 4 billion baht to 5 billion baht ($120 million to $150 million) in the app, Thana said. SCB will also seek investors for the app, he added.

Its travel feature will include hotels, flights and car rental and will launch in February next year ahead of Songkran, Thailand's new year festival in April.

Its groceries service will focus on premium products and shops that do not exist on other apps, Purple Ventures Managing Director Srihanath Lamsam said.
