The region, which has 15,000 residents, covers Mission Dolores Park through the Castro and Duboce Park Neighborhoods and up to Alamo Square Park.

We covered the company previously here.

This could effectively double Meraki’s users. It has 15,000 users already. The question is how it plans to make money, if it has to keep acting as a catalyst by giving these away or relying on philanthropists to pay for them.
