GoFundMe is a generosity powerhouse – it's helped people raise a total of more than 5 billion dollars for all kinds of causes and pet projects. Rob Solomon is its CEO. Late last year, Solomon made a bold move – GoFundMe no longer takes an automatic cut of the money people raise. Now GoFundMe itself runs purely on donations. 

Solomon didn't think he wanted to be the CEO of GoFundMe when he first got the offer – he saw people using it to raise money for cat toys – but he soon changed his tune. I talked to him about the future of using tech to do good, the primacy of trust in today's landscape, and his advice for Facebook's Mark Zuckerberg, who's facing his own trust crisis.
