Shopping app firm Mallzee has been included in a list of the top 100 fastest-growing private companies in the UK.

The Edinburgh-based firm came in at 84 in the report compiled by independent research agency Beauhurst and Syndicate Room.

The report identified the companies that have increased in value most since 2015.

Cally Russell, founder of Mallzee, said: "As retailers face challenging times more and more of them are turning to new ways to develop product and ensure they don't buy the wrong stock, we're now helping some of the biggest names in the business do just that."
