10/7/2016: Postmates has struggled to raise money to fund its on-demand deliveries business

Behind the scenes, Postmates has also had trouble securing the additional funds it has chased for the better part of this year. Sources familiar with the matter told Quartz that Postmates has been in talks to raise a Series E round of at least $100 million, a figure that has also been reported by Bloomberg and TechCrunch. The funding is being led by Founders Fund, the venture-capital firm co-founded by Peter Thiel and an existing Postmates investor. It would value the company at around $450 million, the same as its series D valuation, sources said.
