Mrsool is a Saudi on-demand delivery company founded in 2015 by Ayman Al Sanad and Naif Al Samri, headquartered in Riyadh. The platform connects customers with independent couriers through a mobile app, and pioneered a chat-based ordering model that lets users describe the items or errands they need and couriers bid to fulfil them. It operates across Saudi Arabia, Egypt, and Bahrain. The company grew rapidly, reaching millions of registered users and a large network of couriers, and became one of the region's most downloaded apps. In 2020 it acquired the naming rights to King Saud University Stadium, renaming it Mrsool Park. In June 2025, NOMW Capital acquired a majority stake in the company. Mrsool positions itself as one of the leading on-demand delivery networks in the Kingdom.
