Classrooms by the station, with few rivals around

Haruto opens new branches for a chain of cram schools in Osaka. Parents pick a school their children can walk to from the station. He needs classroom space near a station, with few rival schools close by. He walks the streets around Umeda and Tennoji, checks the agents’ windows, and counts rival signs by hand. By the time he finds a good floor, someone else has signed the lease. With xMap Flows, Haruto built Chalk. Every morning at eight, around Osaka’s busiest stations, Chalk finds the office space for rent within five minutes’ walk of a station, keeps the new ones, counts the cram schools around each, keeps the floors with two rivals or fewer, and posts them to his team. On Tuesday, Chalk finds a second floor four minutes from Tennoji station, listed overnight, with only one cram school nearby. Haruto views it at ten and signs by lunch. It opens in spring with sixty students. Haruto stopped walking the streets for space. Now he sees it first.
