1. Jon Reynolds
29, SwiftKey, British
Jon Reynolds’ mission at SwiftKey, the London-based start-up he founded with fellow Cambridge student Ben Medlock, has been to make technology adapt to human needs, not the other way round.
After completing a physics degree and working in the civil service, Reynolds observed that people were hammering out an increasing amount of work on their mobiles but struggling with the limitations of a shrunken keyboard. He and Medlock set about solving the problem — not as a matter of typing but of language — by developing a predictive algorithm that allows users to swipe fluidly across the screen instead of jabbing.
The technology works by analysing the context of what you are typing and anticipating your words according to your language patterns. It is in use on more than 250 million devices worldwide — including the computer attached to Stephen Hawking’s wheelchair, for which the company developed a special language model to assist him in speaking and writing his lectures and articles.
“Mobile phones are set to evolve from being the most ubiquitous technology in our lives — always with us, always switched on — to the most human technology — always understanding, always pre-empting,” Reynolds told the FT last year.
“This is the change we’re part of and, in some ways, leading.”

19, Summly, British
While many students are forlornly counting their pennies, D’Aloisio, an undergraduate at Oxford university, is already sitting on a self-made fortune. In 2011, when he was just 16, he founded Summly, an app that algorithmically summarises the news for the smartphone generation. It was snapped up by Yahoo for $30m in 2013.
Today, D’Aloisio splits his time between his studies in the UK and working in California as a project manager at Yahoo.
4. Emily Brooke
29, Blaze, British
The greatest cause of cyclist fatalities is being caught in the “blind spot” as a vehicle cuts across an unseen bike. Blaze’s “Laserlight” device aims to prevent this by projecting a beam of light up to six metres in front of the bike. Brooke developed the idea during a product design degree at the University of Brighton.
Blaze has raised $500,000 from, among others, serial entrepreneur Richard Branson and Index Ventures, one of Europe’s leading tech investors.
