Background
Aaron Leitner is a seasoned investment professional with a career spanning nearly four decades in global financial markets. He launched his career on Wall Street in 1986 as a Financial Consultant at Shearson Lehman Brothers, one of the era's most prominent investment banks. He subsequently served as a Portfolio Manager at Prudential Securities before relocating to Israel in 1995. Over the years, he also held portfolio management roles at Wells Fargo Advisors and positions at Lehman Brothers Tel Aviv and Robertson Stephens Evergreen.
Aaron currently serves as Deputy Chief Executive Officer & Partner and Global Investment Strategist at Tandem Capital Asset Management, a privately owned investment house headquartered in Ramat Gan, Israel. Tandem Capital has operated for over 50 years, specializing in global portfolio management for private, corporate, and institutional clients. The firm offers a range of services including personalized asset management, institutional investment solutions, alternative investments (notably Israel's first open-ended fund providing loans against U.S. real estate assets), and international account opening services across Switzerland, the United States, and Luxembourg.
In addition to his institutional role, Aaron is identified as an angel investor with an interest in seed-stage opportunities. His extensive cross-border experience spanning Wall Street and Israeli capital markets gives him a distinctive vantage point for evaluating early-stage companies and global investment opportunities.
