Bear Grylls is today's most intricate hiker, who at 23 became the youngest Briton to conquer Mount Everest, a TV presenter, writer, former special forces man and author of several world records.
Grylls has supported Ukraine since the early days of the full-scale war.
His educational company BecomingX is partnering with Amazon and Accenture to develop the BecomingX Ukraine learning platform for Ukrainians.
In December 2022, the famous traveller visited Ukraine with a film crew. The result of that visit was the film "War Zone: Bear Grylls meets President Zelensky", which was released in the UK and the US on 28 March. The next day it became known that Grylls was joining UNITED24 and would promote the "Rebuilding Ukraine" strand.
He will also become the fundraising platform's first British ambassador.
