Rubicon, the so-called “Uber” for trash, is about to raise a fresh $50 million, according to Breakingviews columnist, Jeffrey Goldfarb. This comes barely six months after the company closed on a $30 million funding round, which included funds from Salesforce.com’s Chief Executive Marc Benioff. The story, which is behind the evil Breakingviews paywall, also notes that Brent Callinicos , Uber’s former CFO, will be joining Rubicon’s board in his first job since leaving the ride sharing app.
