While automatic may be better than on-demand, there’s something truly special about being able to type in exactly what you want, press a button, and have it delivered to your door for the exact same price as going to the store yourself.

That’s what WunWun has been doing for New Yorkers for the past year, and the on-demand service is now making its way to San Francisco.

Launching today in the Mission and Soma, WunWun will offer on-demand delivery of anything to users for a flat rate (plus tip to the WunWun helper). By the end of October, the company will be serving all of San Francisco.

For a courier service (delivering something or performing a task without a purchase), WunWun charges $10. If you ask for a special request like waiting in line for Kronuts or at Madison Square Shake Shack for a shake, WunWun will add an extra $15 for every hour of waiting (after the first twenty minutes of waiting) in line.

The whole idea is that instant delivery of anything should be affordable and accessible to everyone, which is difficult from a business standpoint.

WunWun has not disclosed how much it has raised, save that it is “in the millions.” Right now, the company makes money by selling featured spots to stores in the area, such as Apple, CVS, Duane Reade, Crif Dogs, etc.

Eventually, founder Lee Hnetinka envisions brands advertising against direct purchases at the moment they’re made. For example, if I shop for Degree deoderant, Secret could serve me a deal at that very moment for choosing them, potentially offering a free stick of deodorant with purchase. It could be a powerful (albeit maybe intrusive?) form of advertising, but before that can happen WunWun needs scale.

Alongside the launch in San Francisco, the company is also rebranding with a fresher logo. (Oh, by the way, WunWun is short for “what you need, when you need.”)

Entering a more competitive landscape, and up-to-date look should help. After all, San Francisco has a well-developed space in the on-demand delivery world, with Task Rabbit and Postmates offering their own version of deliveries. However, WunWun brings a different offering to San Franciscans, according to Hnetinka.

“There is no incumbent here yet, and there is nothing better than WunWun,” said Hnetinka. “There is a delivery fee with the other guys or a mass markup with the other guys, but WunWun is about offering the best option. What is a purchasing fee, anyway?”

The market in San Francisco is very different from that of WunWun’s home turf in New York. In the big apple, WunWun fits in because delivery is absolutely expected. Everywhere in NYC delivers, so when something is out of the delivery zone, or simply doesn’t offer delivery, WunWun swoops in to save the day. It’s a competitive, but well-fitting market.

In San Francisco, there are less default delivery options, offering ample space to grow. But others have (obviously) already caught on to this phenomenon, meaning that WunWun needs to move quickly to get a foothold in the new area.
