Companies that make everything from solar panels to renewable-crude oil continue to be big draws for funding from the venture-capital community.But a company that rewards consumers for recycling led The Wall Street Journal’s second-annual ranking of venture-backed clean-tech companies.
The Top 10 Clean-Tech ranking, announced Wednesday at the Journal’s ECO:nomics Executive Conference in Santa Barbara, Calif., seeks to identify green companies with the greatest potential to succeed in an increasingly competitive sector.
A team from venture-industry tracker VentureSource calculated the rankings based on a strict set of criteria applied to 516 U.S.-based venture-backed businesses in clean technology. On March 10, the Journal plans to publish its 2011 Next Big Thing ranking of the top 50 US venture-backed companies across all industries, drawn from more than 5,700 firms. (VentureSource is owned by News Corp., which also owns Dow Jones & Co., publisher of the Wall Street Journal.)Candidates were analyzed on the amount of capital raised in the past three years; the track records of each company’s founders, managers and investors; and the percentage change in its valuation in the 12 months ended Nov. 30.Recyclebank, which provides recycling-rewards programs in 29 states and the U.K., has had a growth spurt since its 2004 launch. In October, the New York-based company brought on Jonathan Hsu, former head of onliine ad firm 24/7 Real Media, as its chief executive.Here is the WSJ Top 10 Clean-Tech Companies
