Mark Major is a kiwi tech entrepreneur from Wellington whose back-breaking injury was instrumental in his first success, Plummet Free Fall. He can't code, and isn't great at drawing. Instead he used his experiences of freefalling - losing his job, and falling down a construction shaft, as inspiration to create a slapstick mobile iphone game. Plummet Free Fall, has now been downloaded more than 350,000 times and was number one on iTunes in four countries: New Zealand, Russia, Ukraine, and Belarus. His latest project is, Plunge Free Dive, which he's developing in tandem with the world record freediver, William Trubridge, to raise awareness of the plight of Maui's dolphins.
