The momentum created by the mayor's trip will help create a climate even more favorable to attracting the innovative Israeli companies that command the attention of the world. The Philadelphia region has a core group of venture-capital and private-equity funds that have invested in Israeli companies. We must think of ways to attract more such entities here. These funds typically demand that their portfolio companies be in some proximity to the fund, which is one reason cities like Boston, New York, and San Francisco have been able to attract so many start-ups. If Philadelphia is to attract the most innovative companies, we need a more robust funding ecosystem. The mayor's trip helps to address this need.
