Sergey Petrossov

Private aviation entrepreuner, Florida

When Sergey Petrossov first began  flying on private jets back in 2009, the drawbacks of the rigid, almost antediluvian booking system quickly became apparent, so he began working on an app that would streamline the process. In 2013, he launched JetSmarter, which allows users to scroll through the network of more than 800 air carriers, all of which can be rented by individuals or, in true Uber-style, shared with strangers. The app has since been downloaded by more than 800,000 users. jetsmarter.com

Ha Lam

Entrepreneur, Ho Chi Minh City

Lam is the co-founder of triip.me, a web-based platform that enables travellers to book tours directly with approved local experts. Lam's idea stemmed from her initial job giving free tours to improve her English. A mother of three, she sold her family home to focus on the fledgling company while surmounting Vietnam’s embedded gender bias. The company now boasts a presence in 655 cities and 98 countries, with New York at the top of the list. ‘We knew from first hand experience, the challenges people face in exploring a culture in a truly authentic way,’ she says. ‘The platform allows anybody with an idea, the ability to create a limitless number of one-off tours, rooted in local knowledge.’ www.triip.me
