About the company: 
Founded in 2011 and located in San Francisco right next to Caltrain, Postmates is transforming the way local goods move around a city by enabling anyone to get any product delivered in under one hour.  Our revolutionary urban logistics and on-demand delivery platform connects customers with local couriers, who purchase and deliver goods from any restaurant or store in a city.  With the largest on-demand delivery fleet in the country, we currently operate in 16 cities across the country and continue to expand each month.  We are well-funded by Spark Capital, Founders Fund, and Matrix Partners (full list below), and our Series B was raised earlier this year.
