DoorDash announced on Tuesday that it has acquired rival food delivery service Deliveroo and the SevenRooms restaurant technology company in separate deals.

U.S. meal delivery firm DoorDash will buy Deliveroo in a deal valuing the British rival at about 2.9 billion pounds ($3.85 billion), the companies said, banking on a bigger reach and local expertise to take on competition.

The combined group will have a global presence in over 40 countries, serving around 50 million monthly active users, the companies said.
