Rewarder Closes $7 Million Round to Build a Social Marketplace

San Francisco-based Rewarder, which is building an online marketplace where people hire each other for their knowledge, has raised $7 million in capital. The company’s first round was led by Granite Ventures and Radar Partners, with other angels participating, including Ron Conway, David Lee, and Kenny Lerer. While in private beta, more than 100,000 people used the platform for a variety of activities, like paying someone to build a travel itinerary, or posting a reward for anyone who can find a rare pair of shoes.
