Throughout 2019, the British technology and startup scene has been roiled by powerful forces.

Political uncertainty, the the distorting financial impact of mega-funders like SoftBank, and increased public skepticism about tech's utopian promises have all left a mark.

It would be easy to feel gloomy. But the technology industry remains a major bright spot for the UK economically, bringing in £184 billion in revenue last year. And the sector is full to the brim of exciting entrepreneurs chasing world-changing ideas, hitting new milestones and breaking new ground.

Every year, Business Insider publishes the UK Tech 100 - our list of the 100 most interesting, innovative, and influential people shaping the UK tech scene, whether that's visionary founders building global firms out of Britain, or regulators grappling with Silicon Valley titans.

This year's constellation of entrepreneurs, technologists, investors, scientists, and critics demonstrates that the UK is easily capable of building a wide range of fast-growing, global businesses that attract serious investment both here and abroad - while also leading the pack on grappling with tech's social impacts.

Our ranking focuses on those who have done cool or impactful work since last year's UK Tech 100 in October 2018- whether that's building a fascinating and fast-growing company, having a good eye for red-hot investments, or riding the mercurial wave of internet virality.
