Less than 24 hours after Oakland-based Mosaic allowed crowdfunding campaigns in January 2013 in which investors could pitch as little as $25, they raised enough money to fund four clean energy projects in California for affordable housing projects. More than 400 investors raised $313,000. The investors, on average, paid about $670 each.

Last week, Mosaic launched a new platform on their site, allowing people to finance solar arrays on homes, in addition to the commercial projects already being funded.

In its seed rounds, Mosaic raised $3.4 million from venture capitalists. In 2012, Mosaic received a $2 million grant from the Department of Energy.
