In a mushrooming sexual discrimination scandal, CEO Travis Kalanick has been forced to take a "leave of absence" from the company, following the resignation of his head of business development Emil Michael. A full report of Eric Holder's recommendations for the company includes widespread changes in hiring and pay practices, board independence, management training, internal controls and a rewriting of it's official corporate values. However, the one thing the report doesn't address is the potential impact on—and from—Uber's largest investors.

In addition to Wall Street's biggest banks like Goldman Sachs, Morgan Stanley, and BlackRock, many 'angel' investors, who were early backers of Uber, helped launch the company. Co-founders Travis Kalanick and Garrett Camp also provided seed money.

Notable names, according to Crunchbase, include Adam Leber, who was a talent manager for Britney Spears and Miley Cyrus, among others. Also on the list, Babak Nivi, founder of Angel List and Venture Hacks. Woman-run Bechtel Ventures also provided $1.3 million in Uber's first money-raising round. Bechtel was founded by Robin Sloan Bechtel, a new media executive credited with marrying Hollywood and the Internet by fostering partnerships with studios and YouTube and Facebook. Another exception to the male-heavy investor list is angel investor Cyan Banister. Gary Vaynerchuk, founder of Vayner Media, was an early stage investor, according to Crunchbase, along with Jason Calacanis, Josh Spear, Alfred Lin, Bobby Yazdani, David Sachs, Dror Berman, Jeremy Stoppelman, Josh Spear, Kevin Hartz, Khaled Helioui, Mike Walsh, and others. The full list on Crunchbase can be seen here.

Other notable investors, albeit at later rounds, include Shawn 'Jay Z' Carter, Jeff Bezos, the founder and CEO of Amazon.com, Fidelity Investments, and Axel Springer, the parent company of The Business Insider. Uber has raised more than $12 billion over fifteen rounds and has been valued as high as $70 billion, making it the #1 unicorn.

Of the 25 board members and advisors, 4 are women according to Crunchbase, including Arianna Huffington, founder of The Huffington Post.
