DataKind is a non-profit that connects data scientists with social organizations. Many non-profits and NGO's cannot afford data scientists, but DataKind is hoping to change this.
I attached a great Ted Talk by the founder, Jake Porway. For those of you don't watch the whole thing...he talks about the importance of data science and how non-profits can use data to make a greater impact on humanity. He also mentions some projects that have come out of this, such as analyzing if NYPD police was using racial discrimination.
