While Strenger makes some good points, I disagree with his overall conclusion. The reason why Israeli tech companies grab the quick "exit" and don't hang in there for the long run is because of the venture capital funds that invest in these companies. VC funds can't afford to wait 10-15 years until the company becomes another Amdocs. The funds exert tremendous pressure on the companies for an early exit so the fund can make 5-10x on their investment for their investors in order for them to then go out and raise their next fund for even more money. That is a much bigger problem for the high-tech industry in Israel.
