Uber filed regulatory documents Thursday for its highly anticipated public offering. Menlo Ventures, a prominent Silicon Valley venture capital firm, led Uber’s $32 million Series B fundraise in 2011. Shawn Carolan, who co-led Menlo's original investment, says that he's confident Uber is on the right track, citing its willingness to experiment with new lines of business like UberEats. He says that founder and ousted CEO Travis Kalanick played an undeniably crucial role in the success of Uber, but also acknowledges that his management style led to big problems at the company.
