There’s something special about the number 100. In sports, the American football field is 100 yards long. In science, 100 degrees Celsius is the boiling temperature of water at sea level. In finance, most currencies are divided into 100 subunits.  So, when a high growth start-up I invested in five years ago increases in value by 100 times, for me, it is a special moment…and worth pausing to write about.
