Earlier this year, I hired a house cleaner. I wouldn't have done so normally, but my place was a mess, I was busy at work, and I saw an offer on Facebook that looked too good to be true — a San Francisco start-up called Homejoy was offering home cleanings in the Bay Area for $19. (Not $19 per room or $19 per hour. Just $19.) So I booked an appointment through Homejoy's website, and a day later, a young man showed up at my door.
As the cleaner laid out his tools, we made small talk, and I asked him where he lived. "Well, right now I'm staying in a shelter in Oakland," he said. I paused, unsure if I'd heard him right. A shelter? Was my house cleaner — the one I'd hired through a company that has raised $40 million in venture-capital funding from well-respected firms like Google Ventures, the one who was about to perform arduous manual labor in my house using potentially hazardous cleaning chemicals — homeless?
