Jan Hammer has a knack for finding promising startups that others miss. He was the first institutional investor in Adyen (a payments company that went public in 2018) and even believed in Robinhood (a stock trading app) when over 70 other investors rejected them (Robinhood IPO'd in 2021). His investment eye extends beyond these two examples, with involvement in Wise (international money transfer), SafetyCulture (operations management app), and Capitolis (capital markets app). Hammer joined the investment firm Index in 2010, bringing his experience from working at a private equity firm and an investment bank. This Czech-born investor has been recognized for his talents, ranking fourth on the Midas List Europe in 2023.
