While there are quite a few on-demand delivery apps out there, Quiqup has some pretty impressive backers, including Delivery Hero and Global Founders Capital (the venture arm of Rocket Internet). They also go beyond food delivery by offering to pick up just about anything you could want and delivered to where you are.
This allows users to skip lines (which is a big deal in London), thereby saving time and reducing stress. Instead of next day delivery, Quiqup is instant and hassle-free. They also emphasize a more human touch by focusing on local stores and offering suggestions for complimentary items. Between their trusted staff (known as Quiqees) and reliable technology, your safety is ensured. They even feature Quiqees on their site.
