Grubhub is a leading online and mobile food ordering and delivery marketplace based in the United States. It was founded in 2004 by Matt Maloney and Mike Evans in Chicago, Illinois. The company's headquarters are located in Chicago.

Grubhub operates as a platform connecting hungry diners with restaurants in their area. Users can browse through a wide range of restaurants and cuisines, place orders, and have their food delivered or pick it up themselves. It also provides the option for users to schedule orders in advance.

Grubhub's platform is available on both desktop and mobile devices, allowing customers to order food conveniently from anywhere. On a global scale, Grubhub operates primarily in the United States. It does not currently have significant international operations or subsidiaries.

However, it does partner with local restaurants in over 4,000 cities across the United States, serving more than 23 million active diners. In terms of market position, Grubhub is considered one of the leaders in the online food delivery industry in the United States. It faces competition from other major players such as Uber Eats, DoorDash, and Postmates.

Grubhub holds a considerable share of the market, with a strong presence in many urban areas. Over the years, Grubhub has achieved significant milestones and made noteworthy acquisitions to strengthen its position in the industry. In 2013, it merged with Seamless, another prominent online food ordering platform.

This merger helped expand Grubhub's reach and customer base. The company went public in 2014 and has continued to grow its market presence through strategic partnerships and acquisitions. As of the latest updates, Grubhub is constantly evolving to meet the changing needs of its customers and enhance its services.

It has recently been acquired by Just Eat Takeaway. com, a European online food delivery company, which is expected to further fuel Grubhub's growth and expand its international footprint. Grubhub continues to be a trusted platform for food ordering and delivery, providing convenient solutions for both restaurants and consumers
