Early in the era of environmental awareness, Hughes was combating climate change and global warming, developing carbon-trading models. As the UN targeted global poverty, Hughes enabled financial inclusion for millions of Africans, creating the highly innovative M-Pesa mobile payments system.

So successful has he been in finding sustainable solutions to those problems that he was awarded an OBE in 2017 for services to innovation in Africa (although, in keeping with a man who lists humility as an important value, you are unlikely to hear it from him).

Now, as Co-founder and Chief Product Officer at M-KOPA, Hughes is not just providing affordable, clean energy, but brightening the lives of millions of people in emerging markets by empowering them with access to financial credit as a means to fulfil their potential. He is also an Executive Fellow at London Business School’s Wheeler Institute for Business and Development, leading on its Digital for Development initiative.

After a degree in veterinary medicine and surgery at Edinburgh University, Reddy headed for New Zealand and established a service specifically for exotic pets, the first in the country’s capital. “I often like things that are quite contrarian, that other people don’t like,” she says. “I saw an opportunity in a niche area that was really underserved.”

Six years later, she was heading back to the UK to do an MBA at London Business School, which she finished in 2016, and the next stage of her career. “I always had that real need to innovate, to take risks, to be excited about something and then move as fast as you can to seize the opportunity. I wanted to know what else I could do.

“LBS challenged my thinking on how to build a business. It increased my expectations of what was possible, so now I think bigger and aim higher. It was great to be surrounded by people who think global, who would say yes to crazy ideas because they share the same huge ambition. Knowing I had that network helped me to make some bold decisions.”
