"No wind, no problem" could be the motto for two of Australia's latest sports tech entrepreneurs, with Andrew Ross and David Trewern reshaping surfing one wave at a time.

From something that can only be done in the right weather conditions at  beaches with waves, surfing will become a year-round sport thanks to innovations from Ross, who founded wave park Urbnsurf, and Trewern, whose Fliteboard already has a growing clientele of business and pop culture identities including Katy Perry, Mike Cannon-Brookes, Rod Drury and Shopify founder Tobias Lutke.
