OnGreen, a social media platform for green entrepreneurs looking for investors, today announced a $1.4 million first round of financing by China Southern Hong Kong Investment, a cleantech investment fund in Shanghai.

The company launched its web site, in July, which has since been used by nearly 300 entrepreneurs in more than 35 countries. Startup hopefuls use the site to upload a business plan, and investors can contact entrepreneurs directly if they’re interested in investing in the idea.

The company calls itself the “LinkedIn” of cleantech investing. “We don’t just connect people with people, we connect ideas with money,” said CEO Nikhil Jain.

It’s an interesting concept, particularly at this point in time. Cleantech investing has been on the decline, and early-stage cleantech funding has taken the biggest hit. The site says that, according to a survey of users, about half of the startups who used the site were contacted by angel or venture capital investors as a result. About 40 percent of users are outside of the U.S.
