On-demand delivery service Postmates announced this morning that it has raised $300 million in additional funding led by Tiger Global Management.

While the company’s press release doesn’t mention this, Fortune reports that the deal valued Postmates at $1.2 billion. Tiger’s Scott Schleifer is joining the board of directors.

Postmates does say that it’s completing “millions” of deliveries every month and is profitable in 90 percent of its markets, and that over the past four years, gross margins have “improved dramatically to nearly 50%.”

Over the past few months, Postmates expanded into more than 100 new cities (it’s now available in more than 400 U.S. cities, as well as Mexico City) and also announced partnerships with companies like Instacart and Walmart.

Postmates previously raised a $140 million round at a $600 million valuation in 2016. More broadly, it looks like VCs aren’t backing away from the on-demand delivery market — DoorDash, for example, recently raised $250 million at a $4 billion valuation.

“The transformation of how commerce moves in cities demands that we build the most innovative tools for businesses to keep up and distribute their products to the modern consumer — efficiently and cost effectively,” said Postmates CEO Bastian Lehmann in the release. “Postmates is proud to be the first and largest on-demand network that is enabling the growth of retail across the country, and today’s investment accelerates our ability to pair technology with the vitality of our neighborhoods.”
