"I have always thought there was something potentially magical about tech," Paul Miller tells the Evening Standard.
"If the product doesn't lead to a more equal and sustainable world, Miller isn't interested."
Miller, 44, is the CEO and co-founder of London venture capital firm Bethnal Green Ventures, which backs socially conscious start-ups that tackle complex problems.
It's all part of Miller's mission to make the world a better place.
"If you understand a particular problem really well, and if you can empathise with people, you're in a better position to create a successful product than somebody who's already a millionaire or billionaire," he tells the Standard.
Miller's parents were social activists growing up in Malawi and Romania.
"I didn't think it was unusual at the time, but a lot of my friends and family growing up were proper activists," he says.
"I learned a lot from one man I knew as an early teenager.
It was only later that I realized he was one of the key figures in the Anti-Apartheid movement."
