How Israel builds its hi-tech start-ups

Many of the new companies in Israel are founded by individuals who have come out of Unit 8200 - Israel's equivalent of Britain's GCHQ or America's NSA - a "signals intelligence" agency which has moved heavily into cyber-operations.

So how does 8200 feed into the private sector? One man who knows is Nadav Zafrir. He joined 8200 in 2005 and ran the organisation between 2009 and 2013. He is now co-founder and chief executive of Team 8, a company-building platform based around cybersecurity which aims to found and establish five companies in five years.
