Indie Fund's first title, Q.U.B.E, has sold over 12,000 copies after 4 days on Steam, allowing developer Toxic Games to repay the investment of $90,000.
Indie Fund offers independent developers flexible investments. Toxic Games approached the fund about a $42,000 investment in August 2010. In January 2011 Indie Fund added another $37,500 to the project.
"We are very happy that we were able to fully fund the game, as it was important to us, and to Toxic's future as independent developers, that the team shipped the best game they could," said Indie Fund, a collective that include Braid's Jonathan Blow and Kellee Santiago of thatgamecompany.
"Our goal is to help developers get and stay independent and it will take some time to see if we've achieved it. With the investment already paid off and discussions in progress about bringing Q.U.B.E beyond PC, we're feeling pretty hopeful."
Other Indie Fund titles currently include Dear Esther, Faraway and Monaco. While the project doesn't accept direct submissions, it encourages developers to catch its attention at conferences and through the games industry press.
