Can tech help San Francisco’s homeless?

Del Seymour lived on the streets in San Francisco’s Tenderloin district for 18 years, hustling for his next fix. For San Franciscans, this gritty neighborhood is synonymous with homelessness, drugs and destitution. It’s also home to 17 tech companies — including Twitter, Dolby Laboratories, Spotify and Zendesk — attracted in part by tax breaks and other incentives from the city. This makes the Tenderloin and its neighboring Mid-Market area a weird study in contrasts, as thousands of young tech professionals step around the area’s poor and homeless on their way to work.
