At 15, animal aficionado Nadav Ossendryver developed a website for crowd-sourcing wildlife sightings in the Kruger National Park. Four years later, Ossendryver has over 500 000 people in his social media community and the Latest Sightings YouTube channel is the most viewed South African YouTube channels in the world, reaching nearly 400 million people.

Ossendryver’s goal is to expand worldwide and make the data he collects more readily available to various research projects, conservation efforts and academic institutions.
