Should Uber’s rocky initial public offering spoil the appetite of investors for Postmates, the meal delivery business expected to go public in the coming months?

Uber, of course, is primarily a ride-hailing business, but the company’s Uber Eats meal delivery unit is its fastest growing segment, accounting for 13% of total revenue last year. Postmates, which filed confidential IPO paperwork with securities regulators in February, is also seeing strong growth, bringing in roughly $400 million in revenue in 2018, a figure that could double this year, according to a person familiar with the business. Private investors are bullish enough on the category that a rival, DoorDash, is seeking to raise new funding at a valuation as high as $12 billion, a huge jump from a few months ago.
