Havas Media has overseen the business since 2012.
Founded in 2000, Just Eat acts as an intermediary for more than 40,000 independent takeaway food outlets and customers.
The company, which has its headquarters in the UK and operates in 13 countries, hired The Red Brick Road in July last year as its lead creative shop.
The Red Brick Road created a campaign, called "mini fist pump", that launched in September and comprised TV, social, digital and PR activity. It showed people celebrating life’s small victories with a fist pump.
The company sponsored Take Me Out, the ITV dating show, in 2014. It also sponsors the Championship football team Derby County, whose shirts bear the brand’s logo.
