An online marketplace for local services, Thumbtack is a startup that seeks to connect customers to trustworthy professionals. Only two years after launching in 2009, the company has attracted more than 150,000 local businesses to its website and continues to expand rapidly. Growth was slow at first, but when the economy cratered, hundreds of businesses reached out to Thumbtack as a way to market their services on the cheap. After the site hit critical mass, largely thanks to a 100-plus-strong team in the Philippines that has been vetting and integrating new additions to the site, letters of interest poured in.

The 11-person U.S.-based team works out of a converted industrial building in downtown San Francisco.
