You may not have heard of Zenobe, but it is working on technology that could change the world. Zenobe is a British unicorn - a company valued at $1 billion or more - that is developing technology that will benefit our children and our grandchildren's generations, according to co-founder James Basden. Donald Trump, the US president, may have caused uncertainty for fast-growing technology businesses, but he won't stop the energy revolution.

In this episode of the Business Leader Podcast, James Basden joins Graham Ruddick to talk us through the story behind one of the UK's fastest-growing companies and one that could be key to driving long-term economic growth.

Zenobe is on Business Leader's list of Great British Billion-Pound Businesses. Here is the full list, brought to you in association with Deutsche Bank Wealth Management.
