Just Eat Takeaway operate various food ordering and delivery platforms in twenty countries,[4] where customers can order food online from restaurants’ menus, and have it delivered by restaurant or company couriers directly to their home or workplace using an app or website.

Initially, Groen wanted to deliver all kinds of consumer goods; however, he noticed that food deliveries had the most demand, and decided to make this the company's primary focus.

Thanks to broadband internet becoming mainstream around 2003, the business started growing massively, and Groen decided to quit his studies to focus on the company.

[17] In August that year, it stopped doing business in the UK, selling its customer portfolio to rival Just Eat.

[25] Although Just Eat became a subsidiary of Takeaway.com on 3 February 2020, the British Competition and Markets Authority ordered on the following day that no integration should take place and that the brands should be kept separate until their investigation is completed.

[26] On 22 April 2020, the Competition and Markets Authority announced that it was unconditionally approving Just Eat's merger with Takeaway.com, following an investigation.

[34][35][36] On 20 April 2022, Just Eat Takeaway announced it was considering a full or partial sale of Grubhub, of which it fully completed its purchase in 2021.

[37][38] The consideration is based on investor pressure and decreased profits, with Just Eat Takeaway's entire market capitalisation lower than the price for Grubhub.
