Mosaic is a solar project finance company based in Oakland, California. Founded in 2010, Mosaic enables crowdfunding of loans for solar development projects. For that reason, GigaOM referred to the company as "the Kickstarter for Solar". Through this model, the company aims to democratize the social and environmental benefits of clean energy. Mosaic is a certified benefit corporation.
In initial tests, Mosaic has facilitated about $1.1 million in private investments from 400 people to finance 12 rooftop solar plants in California, New Jersey and Arizona.
In Spring 2012, Mosaic financed five solar power plants through their zero-interest investment model. 400 people invested over $350,000 in these projects which created 73 kW of clean solar energy for local community organizations—saving the organizations more than $600,000 on their utility bills while producing over 2,700 job hours for local workers.
In September 2012, Mosaic financed its first solar power plant that also offered a return on investment for investors. 51 people raised over $40,000 in just six days to finance this 47 kW project for the Youth Employment Partnership in Oakland, California. With a 6.38% annual return over a 5 year loan period, a $200 investment would yield $272 by the end of the 5 years.
On January 7, 2013, Mosaic launched an online platform to let individuals invest as little as US$25 in specific solar projects while earning a 4.5% annual return on their money. Mosaic provided capital to developers at a 5.5% interest rate, took a 1% fee, and investors could expect a full return of their investment in nine years. Mosaic sold out its first public projects in less than 24 hours, with over 400 investors putting in $300,000+ and an average investment of $700.
On April 8, 2013, Mosaic announced that it had received approval to sell $100M worth of solar investments to the California public. As part of the announcement, Mosaic released another project on the Ronald McDonald House in San Diego, which promptly sold out in just a few hours.
On March 6, 2014, Mosaic announced that it would begin offering crowdfunded loans to homeowners who would like to install solar. 
As of May 2014, Mosaic charges a .5% platform fee, down from 1%.
Mosaic raised $3.4 million in Series A funding in 2012 to grow their solar investment marketplace. Mosaic was awarded an additional $2 million grant from the US Department of Energy as part of the SunShot Initiative.
