Grubhub is an online and mobile food ordering platform that connects diners with local restaurants. It began in 2004 and now partners with over 75,000 restaurants across the US. Grubhub's business model involves charging restaurants a percentage-based commission for each order placed through its platform. It has experienced significant growth through acquisitions and partnerships. Key competitors include Uber Eats, Amazon, and other food delivery startups, but Grubhub is predicted to continue succeeding by expanding its large network of restaurants and active diners.
