Who knew that package delivery would become a hot space, especially when it involves installation of physical lockers? Last week, we uncovered that Google’s recent acquisition, Bufferbox, was planning to invade the San Francisco Bay Area with its shipping service. Of course, after being acquired, nobody knew what would become of Bufferbox, so another Y Combinator company, Swapbox, stepped in to fill the potential void. I spoke with Swapbox’s founders today and learned that their plans and strategy are “unchanged,” and that the team knew that Bufferbox would eventually come to the Bay Area, expanding from its current locations in Canada. Swapbox recently installed its service in San Francisco’s Nob Hill section, mostly because of the concentration of people in the area.
