  • “Even among the hyperactive overachieving techies in his cohort, Martin Varsavsky stands out. He's built more successful businesses--six--than all but the most prolific serial entrepreneurs. He's also fathered more children--six as well--than all but the most prolific dads. Yet at 56, Varsavsky, one of the most recognizable figures in Europe's tech scene, is going for something of a "lucky seven."
