Ryan Graves has resigned from Uber's board

Uber's first employee, Ryan Graves, has resigned from the board of directors just two weeks after the company went public. Graves was one of the only remaining allies of Travis Kalanick who was ousted as CEO in 2017 following multiple scandals related to Uber's poor corporate culture. Graves left Uber in 2017 after serving as senior vice president of global operations but remained on the board alongside Kalanick. It is likely that the new leadership under CEO Dara Khosrowshahi is looking to reduce the power of Kalanick on the board. According to Business Insider, Graves' personal stake in Uber is worth $1.4 billion.

Lime's co-Founder Brad Bao takes over as CEO

Scooter startup Lime is changing CEO as Brad Bao takes over the role from his co-founder Toby Sun. Sun has been the founding CEO since November 2017 and led the company through multiple rounds of financing reaching a valuation of $2.4 billion. Sun will now report to Bao and focus on future research and development, as well as company culture. Before Lime, Sun held a variety of consultant roles and worked at an investment firm.

Andersen was previously employed at Amazon from March 2011 to June 2018, serving in a variety of roles, most recently as Vice President of Finance supporting Amazon's digital video business.
