Postmates, the US online food delivery start-up, has raised $300 million in venture capital funding, boosting its financial firepower against well-capitalized competitors including Uber and SoftBank-backed DoorDash.

The latest round led by Tiger Global Management values Postmates at about $1.2 billion, including the new funds, according to a person familiar with the matter, up from $600 million in 2016. It more than doubles the total funding Postmates has raised in its seven-year history.
