The business sector began to understand the hidden potential of these investments only in the late 1990s. In 2006 the private investment was four times greater that invested by the OCS (US-Israel Science and Technology Foundation, 2008). Other incubators include NGT in Nazareth, Yokneam in Naiot, Yoznok Haemek in the Jezreel Valley and Kinarot in the Jordan Valley.
