The new chief of the CIA's venture capital organization, In-Q-Tel, has resigned after just four months on the job.

Amit Yoran, who was the government's cybersecurity chief until he left that job in 2004, said Monday he stepped down for personal reasons.

The role of In-Q-Tel's chief executive requires significant travel, and Yoran and his wife — a U.S. government lawyer — have three young daughters.

Yoran said he agreed with In-Q-Tel's board to continue working as a consultant and adviser.

In-Q-Tel — named for "Q," the fictional inventor of spy tools and toys for James Bond — makes about a dozen such investments annually with roughly $60 million it receives from the CIA's Directorate of Science and Technology, the Defense Intelligence Agency, the FBI and the National Geospatial-Intelligence Agency.
