Founded in 2008, San Francisco-based TaskRabbit, an online task-for-pay platform, is growing leaps and bounds. In early December, it received $17.8 million in series B financing and plans to expand from five cities to 12 by next year. But with caution. “For us, we would rather accelerate our growth in a smaller market, creating a continually great experience for our customers," CEO Eric Grosse told The New York Times. "It only takes one subpar experience to generate a negative feedback loop.”
