Yoav Andrew Leitersdorf was among the first VCs to focus almost exclusively on very-early-stage Israeli cybersecurity companies selling into the U.S. enterprise market, building a bridge between Israeli technical talent and U.S. customers well before this became a mainstream VC theme. He deliberately runs a small number of portfolio companies per fund so he can be closely involved in product strategy and U.S. market entry, operating more like a co-founder than a traditional financial investor.

Notable Investments
YL Ventures is a seed-only cybersecurity fund that makes only a handful of concentrated investments per fund and maintains a formal network of 100+ CISOs from Fortune 100 companies who actively help portfolio companies find customers and shape products from day one. The firm operates as an Israel-US bridge, systematically connecting Israeli technical founding teams with U.S. enterprise buyers and global capital, with partners who are former CISOs running hands-on go-to-market programs rather than just providing financial investment.
