Last week I attended the Israeli Venture Association conference in Tel Aviv. Featured was a demonstration pavilion presenting progress on 30 startups seeking venture capital. The big eye catcher (for me) was 'Ticket2Final', an online marketplace where you can purchase options on a ticket to a future sports event. For example, you can buy an option today for a ticket to Stanford in the Final Four. Should your pick be successful, you can buy a ticket at the face price, avoiding the scalpers’ mark-up. However, how does this relate to online gambling? Is it gambling, or is it an 'option' like a stock option? See http://www.ticket2final.com.
Another group is TicTacTi (http://www.tictacti.com), who has technology to overlay interactive video ads over another broadband video stream, although I don't need to see more advertising on the web. Applications are polling and surveys.
Finally, in keeping an eye out for green companies, there is Leviathan Energy (http://www.leviathaneneregy.com) designer of some big (10 meter diameter) wind and wave turbines.
