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

DoorDash's banner $3.9 billion acquisition of Deliveroo has overshadowed a second, equally significant acquisition by the delivery company.

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.
