Atlassian's billionaire Co-Founder Scott Farquhar, who quit his Co-CEO job last year, has completed an Ironman triathlon in Germany. "I set myself three goals for the first year. That was to get fit, spend time with my children and...travel aggressively," the 45-year-old said, while speaking at a conference. He, however, said he "misses the energy" of working as a team.
