Five startups took home prizes worth half a million dollars Tuesday at the California Clean Tech Open awards ceremony at San Francisco City Hall.
The business plan competition, sponsored by Silicon Valley venture capitalists, entrepreneurs, academics and environmental groups, is designed to jump-start clean technology innovation. A day before California Governor Arnold Schwarzenegger signed into law the state’s landmark global warming legislation, several hundred people gathered in city hall to hear San Francisco Mayor Gavin Newsom, VC and clean tech money man Vinod Khosla and other speakers hail California’s green revolution. “We don’t need to wait for permission from the president of the United States” to fight global warming, Newsom told the crowd.
Each winner scored a “startup in a box” package worth $50,000 in cash and $50,000 worth of legal, accounting, public relation and executive search services. Check out the winners after the jump.
