Tech: The 100 coolest people in UK tech

share on:

Business Insider's UK Tech 100.

This is Business Insider's latest ranking of the 100 coolest people in UK tech. We define cool as having done influential and interesting things — whether it's getting a new job, raising money, growing a giant audience on YouTube, or just being really, really good at Fortnite.

It has been an epochal year for the British technology industry, provoking searching questions about protecting people’s privacy and safety, and regulating Silicon Valley’s behemoths.

At the centre of it all was Facebook, humbled by the Cambridge Analytica scandal which took place on British soil. But at the same time there has been cutting edge technological developments, blockbuster funding rounds, and exciting new players entering the space.

Every year, Business insider publishes the UK Tech 100 — a ranking of the 100 coolest people in the UK tech scene. It celebrates the vibrant array of people working to scale companies, develop exciting new research, and shed light on the latest advances (and scandals) in the industry.

We define "cool" as having done influential and interesting things since we last compiled this list in October 2017 — whether that’s getting a new job, raising money, growing a giant audience on YouTube, or just being really, really good at Fortnite.

Scroll on to see the 2018 edition of the UK Tech 100, ranked in ascending order.

100. YouTube’s bolshy British boxer, KSI

KSI is the mouthy YouTuber who has netted millions of pounds by taking on fellow YouTubers in real-life boxing matches.

It’s as much notoriety as it is fame for KSI, who has had to apologise for off-colour remarks in the past, and engaged in bitter vitriol with his most recent opponent: US vlogger Logan Paul.

He is hugely popular with his young fanbase, and this new form of entertainment is highly lucrative. It's a revolution in terms of how YouTubers can parlay their digital fame into offline events.

99. Martin Lewis, the millionaire suing Facebook over scam bitcoin ads

Martin Lewis is best known as the man who helps people save money through MoneySavingExpert.com. But this year, the millionaire made headlines for launching legal action against Facebook over bitcoin ads bearing his name, which scammed people out of cash.

He promised to take Facebook to the High Court, but proceedings have gone quiet as the two parties discuss the possibility of a settlement. Sources close to Lewis think they rattled Facebook, and as a mark of how seriously the company is treating the issue, US executives joined a meeting a 4.30 a.m. to help reach a resolution.

98. Sharon White, Ofcom CEO has tech in her sights

Sharon White is a regulator who commands respect in the media industry. She has taken BT to task over improving the UK’s high-speed broadband network, as well as taking on a huge new role in keeping the BBC in check.

And it looks like firms like Facebook, Twitter, and Google are now in her sights. In an article for The Times in July, White said the "argument for independent regulatory oversight" over these firms "has never been stronger."

She followed this up with a speech last month, in which she outlined a proposal to impose financial penalties on social media firms that fail to remove offensive content in a timely manner.

With the government poised to set out its position on internet safety in a white paper this year, Ofcom could well be handed even more powers.

97. The union thorn in Uber’s side, Steve McNamara

Steve McNamara, head of taxi trade body the LTDA, has been one of the key critical voices holding Uber to account in London.

While the traditional taxi trade was initially divided when Uber first launched in the UK’s capital, it has become laser-like in its criticism, flagging weaknesses in Uber's safety procedures and lobbying City Hall.

As a result, the LTDA played a part in the trial over Uber's London licence, and is even threatening to take the firm to court over lost earnings.

96. Allister Heath, the Sunday Telegraph editor revitalising tech

Under the leadership of Sunday Telegraph editor and head of business Allister Heath, The Telegraph has built up an impressive team of reporters and editors focused on covering technology and startups.

It's testament to the maturation of the UK startup scene that a national newspaper has dedicated an entire new unit to cover it, but also speaks to the expansion of all things technology to the mainstream.

94. Doug Gurr, growing Amazon in the UK — despite Brexit

Amazon's UK country manager reportedly issued a stark warning about Brexit during a meeting between business chiefs and the government earlier this year. Doug Gurr said a no-deal Brexit could spark "civil unrest" within weeks.

The warning, and indeed Brexit itself, is not stopping Amazon from investing in the UK. In June, Gurr said Amazon will create 2,500 jobs in Britain this year, taking its total workforce in the country to 27,500. This includes 650 head office roles.

93. Sir Tim Berners-Lee, invented the world wide web and lives to regret it

Tim Berners-Lee may have invented the web as we know it today, but he's not thrilled at how his creation has turned out. Berners-Lee told Vanity Fair in July that he has been "devastated" to watch the abuse of the web, including high-profile scandals like Cambridge Analytica.

He currently heads up the World Wide Web Consortium, which endeavours to make the web serve humanity, and in late September announced his intentions to decentralise the internet through his open-source project Solid.

Emily Spaven is a veteran British technology journalist — from working as managing editor of cryptocurrency news site CoinDesk to calling the shots at UKTN, a UK-focused tech outlet.

But a little over a year ago she took on a new challenge, and became the UK News Editor for LinkedIn, the Microsoft-owned professional network, where she now works on the UK Daily Rundown news service and is, in her words, "on a mission to increase the amount of quality content and conversations on LinkedIn."

91. Alex Lovén, the richest young entrepreneur in Britain

You’ve probably never heard of Alex Lovén, but this year he quietly became the richest young entrepreneur in Britain after amassing a fortune of £55 million.

Lovén runs online retailer Net World Sports, which he has built from selling sports gear on Ebay and Amazon — all from his modest home in Wrexham, north Wales.

What started as a hobby hawking cricket bats to his friends is now a £20 million business, which manufactures its own products, including one of the best-selling football goals in the world.

The 30-year-old owns 98% of the Net World Sports and runs the company with a single-mindedness that means he counts no-one, not even Jeff Bezos, as his business idol.

"Game of Thrones" star Maisie Williams has partnered with her director friend Dom Santry to create an app with noble ambitions.

Available on iOS, Daisie aims to combat a "who-you-know" culture in the creative industries by connecting people and hosting interviews with big name actors, musicians, and designers. And evidence suggests it’s popular, with a long waiting list to join the app.

Williams was in San Francisco in July talking to investors about the app and has already secured funding from undisclosed venture capital firms. Talks with other backers continue.

87. Andy Serkis, Britain's motion-capture trailblazer

Serkis has stunned the world with his motion-capture performances — from Gollum to King Kong. But Serkis doesn't just perform in motion capture, he pioneers it.

Serkis cofounded The Imaginarium Studios in 2012, specialising in capture technologies. The Imaginarium has worked on films, music videos, and even video games.

The company announced in September that it was partnering with buzzy US augmented-reality company Magic Leap to create digital characters for its augmented reality experiences. Serkis himself will appear as a disgruntled orc.

Serkis's upcoming film "Mowgli" (in which he will star as Baloo the bear) is also an Imaginarium production, and was sold to Netflix in July.

Once a Google product strategist, James Williams is now a research associate at the Digital Ethics Lab of the Oxford Internet Institute.

Williams released his book "Stand Out of Our Light" in May, which argues that social media is hijacking our ability to focus on our broader goals. He believes distraction is the result of tech companies not being upfront about their advertising-based business models.

81. Transport for London’s legal bulldog, Martin Chamberlain QC

Martin Chamberlain represented Transport for London this summer during Uber’s appeal to win back its operator's licence in London.

Laying out the regulator’s arguments, Chamberlain was remarkably cogent and even entertaining in court. In one episode that provoked laughter from the gallery, he relayed how Uber had sent out DIY medical tests to its drivers, which they could easily cheat.

While Uber is the most highly valued and well-funded startup in the world, it was humbled by Chamberlain in a very British fashion.

80. Damian Collins, the lawmaker feared by big tech

It’s safe to say there are few lawmakers in the world who have grasped the complexity of Facebook’s data scandal and the issue of fake news more than Conservative politician Damian Collins.

As chair of the Digital, Culture, Media, and Sport Committee, he has sought to investigate the Cambridge Analytica data breach and all of the rabbit holes it opened up. Such was his committee’s attention to detail, and patient, precise questioning of witnesses, some felt that this was why Facebook CEO Mark Zuckerberg evaded giving evidence to the MPs.

To help with his efforts, Collins took a crash course in coding and has shared information and evidence with lawmakers around the world. Collins truly immersed himself in his task.

In an interim report, his committee said tech firms should be held responsible for the content on their platforms, they should be regulated more tightly, and their algorithms and data usage should be audited.

Appearing in court during Uber’s appeal this summer, and after her maternity leave, Chapman was forthright about the ride-hailing firm’s "appalling" behaviour. Uber was since granted a temporary licence, but the firm knows it has to tow the regulatory line.

Andrew Fisher was at the helm of Shazam when it sold to Apple in December 2017 for a reported $400 million, instantly making it the most valuable UK music app ever made and Apple’s biggest acquisition since it bought Beats for $3 billion.

Apple’s acquisition of Shazam was approved by the European Commission in September, following an investigation into whether it would damage competition.

Documents filed with Companies House in the UK show that Shazam made £40.3 million in revenues in 2016 as it increased sales by 14%.

51. Laurel Powers-Freeling, the banker whipping Uber’s UK business into shape

Veteran banker Laurel Powers-Freeling became Uber's first UK chair last November two months after the ride hailing company lost its operating licence in London.

Powers-Freeling proved to be influential, introducing governance changes internally that helped Uber to get its licence back.

Prior to Uber, the Michigan-born businesswoman was CEO of Marks & Spencer's banking division, M&S Money, and a senior adviser at the Bank of England. She's also worked at American Express, McKinsey, Morgan Stanley, and UK fintech startup, Atom Bank.

50. Jimmy Wales, Wikipedia founder turned campaigner

Wikipedia founder Jimmy Wales was on this last year for WikiTribune, his journalism venture aimed a debunking fake news. Wales says the project remains in its infancy, but he is hopeful about its potential.

This year, Wales features for turning his hand to campaigning. Using his own influence and the power of Wikipedia, he has lobbied against sweeping changes to EU copyright laws. It resulted in the European Parliament sending the plans back to the drawing board, before an updated version was approved last month.

If given final sign-off in January 2019, it could require the likes of Reddit to censor content that breaks copyright laws and impose a so-called link tax on firms such as Google. Judging by Wales' activity on Twitter, he intends to carry on campaigning.

49. Charlie Brooker, the creator of "Black Mirror"

Charlie Brooker is an unusual quality in this list. He is someone who has not done anything particularly fresh or different in the past 12 months, but warrants a place because his work just oozes cool.

His Netflix show "Black Mirror" has become shorthand for tech dystopia. Nearly everything Brooker writes is grounded in his real-word anxieties, which he plays out on screen to an often terrifying conclusion. From robot dogs that turn murderous, to an implant that allows a mother to spy on her daughter’s every move, his stories strike a chord because they feel so likely.

Brooker and his cowriter William Bridges won an Emmy for best writing for a limited series or movie for season four episode "USS Callister."

40. Sadiq Khan, the London mayor holding Uber to account

Mayor of London Sadiq Khan played a leading role in Transport for London's fight with Uber over the past year, which resulted in Uber being granted a 15-month licence on condition that it clean up its act.

But that doesn't mean that Khan is done holding Uber to task. He has said the company still has a lot to prove and is seeking powers to limit the number of Uber drivers permitted to operate within the city.

Khan was also vocal about hate speech this year. Appearing at SXSW festival in Austin, Texas he read out hateful, Islamophobic comments that he had received online and urged platforms like Twitter and Facebook do more to fight online abuse.

In a statement sent to Business Insider, Khan said he wants London to remain at the "forefront of global tech." He added: "I want London to be the world’s leading smart city and it’s by working with the kind of fantastic talent found in the UK Tech 100 that we can make this ambition a reality."

Alex Klein is the cofounder and CEO of London startup Kano, which encourages people to get into computing and coding with its brightly coloured DIY computer kits. He's the cousin of Saul Klein, an investor who also appears on this list.

So far, 1.5 million people have created more than 500,000 apps, artworks, games, and more in Kano World (the online home of all Kano creations) in the past year, sharing more than 50 million lines of code in the process.

The company doubled its sales in 2017 thanks in part to the fact that its products were stocked in Apple Stores worldwide and 1,100 Walmart stores. The growth in sales has continued in the first half of 2018, according to Klein.

In July, Kano announced plans to launch a Harry Potter wand that turns physical wand gestures into onscreen spells. The Bluetooth-enabled wand connects to a computer, iOS or Android device before allowing users to attempt a number of Hogwarts-themed coding challenges.

It’s been an eventful year for Britain’s information commissioner, who has taken a leading role in investigating Cambridge Analytica and Facebook over a data breach that impacted 87 million users.

The 18-month probe culminated in her office slapping Facebook with a maximum fine of £500,000 for failing to ensure Cambridge Analytica deleted user data. It may be paltry in the context of Facebook’s giant revenues of $40 billion, but it was a chastening day for the tech giant, and led to calls for Denham to be handed greater powers.

Denham is also the woman in charge of enforcing the EU’s wide-ranging new GDPR data laws, which is also likely to bring the Canadian into contact with Silicon Valley. She told The Observer that her job basically boils down to a simple truth: "Data crimes are real crimes."

From scrappy beginnings in a North London home to raising $500 million from Japanese tech giant Softbank, simulation startup Improbable has come a long way and its SpatialOS platform is starting to find use cases in the gaming world.

Founded by Cambridge graduates Herman Narula and Rob Whitehead, Improbable’s SpatialOS is sold as a platform that allows game developers to "go beyond the design limitations of traditional server architectures." SpatialOS is being used by gaming studio Midwinter Entertainment for its "Scavengers" game, while Automaton Games is using it to underpin a game called "Mavericks."

Improbable raised $50 million from Chinese internet company NetEase in July and, in August, NetEase Games previewed a SpatialOS game called Nostos, which is an open-world survival game built for VR and PC.

Total amount raised: $604.1 million (£464.1 million)

5. Anne Boden, the digital bank CEO who hammered out a partnership with RBS

Anne Boden founded Starling Bank in 2014, and while it’s not as big as rivals Monzo and Revolut, it could be catching up.

It is reportedly looking to raise £80 million, and Boden told the Financial Times in August that Starling had grown almost fivefold since the start of the year, with 210,000 users.

That still puts Starling behind Monzo in raw users, but Boden said that the average Starling account balance is much higher than at Monzo.

Boden also forged a partnership with RBS/Natwest to help build its standalone digital bank, and was awarded an MBE in the Queen’s Birthday Honours List. All in all, she’s had a good year.

Total amount raised: £58 million

4. Samir Desai, overseeing the next big UK tech IPO

Samir Desai is cofounder and CEO at Funding Circle, a peer-to-peer loan provider which has now leant more than £5 billion to over 80,000 UK businesses.

Funding Circle went public in September at a £1.5 billion valuation.

Total amount raised: £250 million
Headcount: 1,000

3. Demis Hassabis, Mustafa Suleyman, and Shane Legg, DeepMind founders

Some of the world’s most sophisticated artificial intelligence agents are being developed by UK-headquartered DeepMind, which was acquired by Google in 2014 for a reported £400 million.

The company's self-learning algorithms have successfully mastered several complex games, including the ancient Chinese board Go, which famously has more moves than there are atoms in the universe. But the next step is to see how these clever algorithms can be used to aid scientific advances in fields like climate change and healthcare.

DeepMind announced in August that it has taught its algorithms to detect over 50 eye diseases with 94% accuracy and it has several other projects with the NHS underway.

The company has grown significantly over the past year to over 700 staff. It has bolstered its London office and opened up new outposts in Paris and Canada.

2. Will Shu, the ex-banker at the helm of Deliveroo

Deliveroo cofounder and CEO Will Shu is competing with tech giants like Uber and Amazon in the increasingly competitive takeaway delivery market. And it's doing pretty well, given reports that both Uber and Amazon have held talks to buy the $2 billion business.

This year, Deliveroo continued to expand into towns and cities around the world and it now has a network of 35,000 riders, with 15,000 of those in the UK, where it has become profitable.

Deliveroo Editions, shipping containers with delivery only restaurant kitchens inside, were launched in new UK cities such as Reading and Brighton, allowing more restaurants to reach new customers without having to rely on high street premises. There are now around 200 Deliveroo Editions kitchens in the UK.

Deliveroo’s relationship with its riders has been a rocky one but this year the company gave them free accident insurance and provided many with first aid training so that they can react to an emergency situation on the roads. They get several other perks, but the pay remains an issue for some.

Total amount raised: $859.6 million (£647 million)

1. Christopher Wylie, the data scientist who humbled Facebook

On March 17, 2018, Christopher Wylie changed the discourse around data and privacy forever.

After months of secret work, the whistleblower went public with claims that the shadowy political consultancy Cambridge Analytica had weaponised the information of 50 million Facebook users during the 2016 US presidential election.

Wylie's claims, made to the Observer newspaper, triggered the most intense scrutiny of Facebook and its hold on the world's data to date. His exposé of Cambridge Analytica, combined with subsequent revelations around Facebook's privacy practices, wiped $60 billion off the social network's value. Facebook CEO Mark Zuckerberg, usually reluctant to give press interviews, felt obliged to go on a media apology tour, which evolved into a global advertising campaign.

Wylie's emergence as a poster boy for data security was timely, coinciding with the EU's new privacy regulation, the GDPR. His shock of pink hair, nose ring, and eloquent turn of phrase have made him TV dynamite, while The Observer's Carole Cadwalladr dubbed him "the millennials' first great whistleblower."

Wylie is not without critics, thanks to his own role at Cambridge Analytica. As a former employee, he helped build what he came to describe as "Steve Bannon’s psychological warfare mindf–k tool," which exploited Facebook data. BuzzFeed also reported on his efforts to set up another political consultancy while he was still in possession of the same controversial Facebook data set.

But his actions humbled one of the biggest companies in the world and turned the usually arcane issue of online security into an urgent, mainstream topic of discussion. Thanks to his decision to blow the whistle, Silicon Valley firms are going through a serious period of introspection.
