Diaspora describes itself as a "privacy-aware, personally-controlled" social network.
The open-source project made headlines earlier this year when Facebook was forced to simplify its privacy settings, after they were criticised for being overly complex and confusing.
The team turned to the fundraising site Kickstarter to raise the $10,000 they thought they would need to build the network.
In the end the team raised $200,642 from nearly 6,500 people.
Mark Zuckerberg, the founder of Facebook, reportedly donated to the project.
