WunWun Is Now Making It Totally Free To Get Anything You Want Delivered To Your Doorstep In San Francisco

WunWun, the app that lets users order anything from any store or restaurant in New York City or the Hamptons without a delivery charge, is launching in San Francisco.

The idea is that WunWun doesn't charge users a delivery fee, meaning that if you order a $5 sandwich and a $4 tube of chapstick, you'll pay $9, plus a tip to the delivery person.

Other on-demand services like PostMates and Instacart charge a delivery fee in addition to the tip.

To make money, WunWun forms partnerships with the stores it serves, getting a discount on items that it doesn't pass on to its customers. The company also has plans to let stores pay extra to have their products featured.

"We're expanding with 'torpedian,' growth," WunWun CEO Lee Hnetinka told Business Insider, admitting that his team made the word up. "We're feeling like we're on fire."

WunWun is rolling out its service in two neighborhoods today - SoMa and the Mission - with the rest of the city getting covered by the end of October.

Although Lee declined to share revenue numbers, but said that it had increased by 400% in the last two months. He also said that once a person has used WunWun five times, they order every day or every other day, and its top 50 users spent over $70,000 through WunWun in the last month.
