German food delivery firm Delivery Hero has invested $235 million in Gorillas, an online grocery start-up, as part of a $1 billion funding round.

Gorillas was founded in May 2020 but has grown at a rapid clip as demand for its service, which ships groceries to people’s doors in as little as 10 minutes, took off during the coronavirus pandemic.

It’s one of several European start-ups competing in an increasingly crowded space. Rivals include Turkish company Getir, British firm Zapp and German peer Flink.
