Meet 2019's Rising Stars of Wall Street from firms like Goldman Sachs, Blackstone, and Apollo shaking up investing, trading, and dealmaking

Feinberg started at the University of Pennsylvania with plans to be a lawyer and had no idea what investment banking even was. It took only a year for him to transfer into the Wharton business program, and the rest is history.

Feinberg worked at Morgan Stanley during the summer of the financial crisis and joined Silver Lake Capital, a private-equity firm in New York, after he graduated. He joined Tiger Global six years ago as the hedge fund run by the billionaire Chase Coleman decided to expand more into the private markets.

In that time, Feinberg estimates he has been a part of 40 to 50 different investments Tiger Global's private-investing team has made, including co-leading the firm's investments in the Brazilian financial-technology unicorn Nubank and the buzzy workout company Peloton. Both the investments were made earlier on in the companies' histories — series B for Nubank and series A for Peloton — a fact Feinberg is proud of.

Feinberg is looking for founders that are inspirational but also grounded, so they don't let their vision get the best of them, while also being able to get employees and investors to buy into the potential of the company.
