One of Google's most high-profile executives in the UK, Vidra was part of Google Ventures' European fund.

He's also behind the Tech Bikers charity effort, started in 2012, where startup founders and employees participate in a long-distance bike race from Paris to London to raise money for charity.
Vidra quit Google Ventures on Christmas Day, weeks after it was announced that the separate fund for European startups would be closed.
The organisation was set up initially to support the thriving startup scene in East London but today it is tasked with supporting startups in tech clusters across the UK, from Edinburgh and Brighton to Manchester and Cambridge.

21-year-old Mustafa Al-Bassam made headlines for all the wrong reasons three years ago — when he was named as one of the individuals involved in the notorious hacking group LulzSec.
LulzSec hit everything from Fox to the NHS, and for his part, Al-Bassam was handed down a 20-month suspended sentence by the UK courts.
He’s now studying computer science at King’s College in London (after a two-year internet ban), and is rising in prominence in the UK tech scene — Forbes recently named him one of its “30 Under 30” to watch in European tech.
Sajid Javid wields considerable power over the UK tech scene: He's the Secretary of State for Business, Innovation and Skills.
The Conservative Party politician is MP for Bromsgrove, and was appointed in the position a little under a year ago, in May 2015.
While some politicians -- like Conservative Party London Mayoral candidate Zac Goldsmith -- have been critical of ride-hailing app Uber's presence in the city, Javid is more positive about the tech, warning about 'heavy handed' crackdowns on the service.
Though he only entered Parliament for the first time in 2010, he's being tipped by some as a potential contender for the Conservative Party leadership when David Cameron stands down.
Holly Brockwell founded technology news site Gadgette in May. It's a gadget and technology news site that's focused on women, an audience that many tech sites struggle to write for.

Total amount raised: $220 million (£152 million)
To most people, emojis are little more than a curiosity -- a way to inject levity, or flirtation, into otherwise dry text messages. But for Jeremy Burge, they're quite literally his livelihood.
The 31-year-Australian is on a mission to catalogue and categorise the pictograms. Over the last three years, he has built a 140-million-pageviews-a-year-business around them almost singlehandedly: Emojipedia, an online encyclopedia of emojis.
Emojipedia began as a side-project, but after interest exploded, Burge went full-time in 2015. He works out of Google Campus in London, and the site also has a developer working for it nearly full-time, as well as a designer who comes on when required.
Entirely self-funded, Emojipedia had six-figure revenues in 2015 -- and that's set to double this year.
Total amount raised: Self-funded, undisclosed
Roland Lamb's startup ROLI wants to revolutionise the piano.
It's behind the 'Seaboard' -- a new kind of musical instrument that looks superficially similar to an electric keyboard, but with far more control and customisability.
The former philosophy student's company launched its third instrument -- the Rise 49 -- in January 2016, and it has bagged $20 million (£14 million) in VC money, with backers including Index Ventures and Balderton Capital.
ROLI has multiple design awards under its belt -- most recently the 'Best of Innovation' award at CES in Las Vegas this year.
Total amount raised: $20 million (£14 million)

For starters, he's a knight. And not just the run-of-the-mill, honoured-by-the-Queen-for-services-to-industry knight. Kingsley is a real knight. He's a keen jouster, breeds warhorses, and spends tens of thousands on custom suits of armour.
When he's not on horseback, he's running Rebellion, an Oxford-based gaming company he cofounded with his brother in 1992.

Total amount raised: $17 billion (£11.7 billion)
The downside to crowdfunding platforms like Kickstarter and Indiegogo is that you don't get any stake in the eventual company your investment helps build. When these companies cash out, it can sometimes leave an bitter taste in supporters' mouths, as was the case for some backers of VR headset Oculus when it sold to Facebook.
That's not the case with Seedrs, a London-based equity crowdfunding platform.
Users invest (as little as £10), and in return, they get a share of the company. It's clearly an attractive prospect: The company recently recently announced that £100 million has been invested through its platform.
It was cofounded by Jeff Lynn, a former corporate lawyer, who serves as CEO. In June 2015, tennis pro Andy Murray joined as an advisor.
The bearded and British Myke Hurley is a professional podcaster who lives 'just outside' of London.

Back in July 2015, Peter Smith was chosen to accompanying British Prime Minister David Cameron on a trade mission in South-East Asia along with a host of other more conventional companies.

Total amount raised: $16.5 million (£11.4 million)

Likely the smartest person on this list, Nick Bostrom is a philosopher who specialises in artificial intelligence, human enhancement, and other topics relating to the future of humanity.
The 42-year-old Swede works as an academic at the University of Oxford, but his writing has mainstream appeal too: Superintelligence, his most recent book, published in 2014, was a New York Times bestseller.

Before joining Darktrace, which is backed by Mike Lynch's invoke capital fund, Palmer was a cyber security technical expert at GCHQ and MI5. During his time at Britain's spy agencies, he was tasked with looking after their IT infrastructure and keeping an eye on their networks.
Total amount raised: $40.5 million (£28 million)
Kieran O'Neill is the CEO of Thread, which helps customers make sense of the world of fashion by matching them up with their own personal stylist through its platform. The stylist learns about users and suggests clothes that they think would suit them. Users can then purchase the items through the site. Thread is free to use, but the company takes a cut of any purchases that you make.
It was announced in August that Thread had raised $8 million (£5.5 million) from investors including Balderton Capital, Google DeepMind cofounders Demis Hassabis and Mustafa Suleyman, and former Saks Fifth Avenue president Andrew Jennings.
CEO Kieran O'Neill started his first online business in 2003 when he founded video streaming website HolyLemon.com while studying for his GCSE. He eventually sold the site for $1.25 million (£814,000).
Total amount raised: $10.5 million (£7.3 million)
Peter Read is a respected London investor who joined the Google Ventures team in Europe when it launched in 2014. Google's European VC fund made a series of investments in companies such as Kobalt and Lost My Name.
However, Read left Google Ventures in July 2015 without announcing why he was departing the high-profile fund. Business Insider reported in August that there had been disagreements within the Google Ventures team in the UK, and that one source of frustration was a reliance on Google's algorithm that helps investors make decisions.
Google ultimately shut down its separate European venture capital fund in December. Out of the five people who launched the team, only two remained. Read jumped ship on his own terms and he's likely to make a return to investing in the future.
Murad Ahmed is the European technology correspondent at The Financial Times. Here he covers tech companies across the UK and Europe, as well as the goings on in Silicon Valley.
In November, he was named 'Tech Journalist of the Year' at the UK Tech Awards, thanks to scoops on Google, Uber, Microsoft, and Europe's startup scene.
After graduating with a degree in law from the University of Cambridge, Ahmed studied journalism at Goldsmith's College. He became a news trainee at The Times, after which he began his focus on the tech sector.
Shami Chakrabarti is a giant of British civil society. She's the director of Liberty, an 82-year-old London human rights organisation.
Liberty's remit extends well beyond the tech sphere -- but in the years since Edward Snowden's revelations about Western governments' surveillance, Liberty has championed digital rights just as it has traditional civil liberties.
A former Home Office barrister, she has honourary degrees from Southampon, Glamorgan, and Middlesex universities, and is the chancellor at the University of Essex. She was even a flag-bearer at the 2012 Olympics in London.
Robin Klein (Saul Klein's father) is a well-known investor in Europe that sits on the boards of several London startups. Klein is also on the Tech City Advisory board and an advisor to Silicon Valley Bank.
During the course of 2015, Robin made a number of investments through Localglobe, the VC fund he set up with his son. For example, he led a £1.1 million investment in online mortgage advisor Trussle earlier this month, alongside Betfair cofounder Ed Wray and former Google UK MD Dan Cobley. He and his son also backed education app Gojimo in a $1.8 million (£1.2 million) seed round in December.
While at Index, Klein invested in Adzuna, Citymapper, EDITED, Farfetch, Geckoboard, MOO, onefinestay, and TransferWise.
Greg Marsh cofounded home swapping service onefinestay in 2009. Marsh, who is CEO of the company, had a busy year in 2015, raising large amounts of funding and bringing in a top hotel executive.
onefinestay, which allows people to stay in expensive, serviced houses in cities around the world raised $40 million (£25.4 million) in June from a range of well-known investors. Marsh also hired InterContinental's chief finance officer, Tom Singer, in a bid to beef up his management team.
Total amount raised: $80.9 million (£55.8 million)
Suranga Chandratillake and Rob Moffat are partners at Balderton Capital, which has raised $2.47 billion (£1.7 billion) in funding to date, making it one of Europe's largest venture capital funds.
Over the last year, Chandratillake made his first Balderton investments into student media title The Tab and online code editing platform Cloud 9.
Moffat, meanwhile, was promoted from principal to partner in January 2015. He led the investment in Carwow when he was a principal investor, and is also a board director or advisor at Qubit, Wooga, Housetrip, Rentify, Nutmeg, Prodigy Finance, and Patients Know Best.
Total amount raised: $2.47 billion (£1.7 billion)
The Tab is a network of student news websites run by editorial teams across the UK and US. It started off as a Cambridge student newspaper, founded in 2009 as the university's first online-only paper. It made headlines after The Sun fell for its April Fool's joke about BNP leader Nick Griffin and for its 'Rear of the Year' competition.
The company announced that it had raised $3 million (£2 million) from Balderton Capital in December, and the money is going towards the expansion of its US site as well as its new general interest site that's not about a specific university.
Editor-in-chief Jack Rivlin told The Guardian that The Tab's had 3.2 million unique visitors in November 2015.
Total amount raised: $3 million (£2 million)
Stephen Hawking is the acclaimed theoretical physicist at Cambridge University who has weighed in on the artificial intelligence debate on multiple occasions over the last year.
For example, Hawking, who has the motor neurone disease amyotrophic lateral sclerosis (ALS), signed an open letter in July calling for a ban on autonomous weapons.
He also revealed in an interview with the BBC that he believes AI could end mankind. 'The development of full artificial intelligence could spell the end of the human race,' he said.
In February 2015, Google appointed Matt Brittin, formerly head of its Northern/Central European operations, its President of EMEA Business and Operations -- the first person to hold the role. In short, he's Google's most senior employee on the continent -- giving him serious influence in tech circles.
Brittin has taken the helm of Google in Europe during a turbulent time for the company: It is being investigated by the European Commission over antitrust allegations due to its dominance of the European search market. More recently Google has come under fire over a £130 million UK tax bill, which critics say is too little.
He originally studied at Cambridge University, where he was a keen rower -- even competing in the Olympics. He subsequently worked for McKinsey & Co., then Trinity Mirror, before joining the search giant.
Headcount: 4,000 (in the UK)
Mike Lynch has been busy reinvesting the money he made from selling Autonomy to HP for over £7 billion in 2011 through his new investment fund, Invoke Capital.
One of his most exciting investments is cybersecurity company Darktrace, which employs former MI5 and GCHQ worker Dave Palmer as its chief technology officer, who also features on this list.
Darktrace, which shares an office with Invoke Capital on Pall Mall in London, was backed to the tune of $18 million (£12.5 million) last March, with Invoke among the main investors.
Jimmy Wales is best known as one of the cofounders of online encyclopedia Wikipedia -- and that recently passed a significant milestone recently, turning 15 years old in January 2016.
But the 49-year-old Alabama-born Londoner has had other accomplishments to note over the last months. In July, his latest project, The People's Operator (TPO), launched in the US.
For those not in the know, TPO is an 'ethical' mobile network that gives a cut of its proceeds to charities of its users' choosing. It also launched social networking functionality in 2015, now framing itself as 'a social network with a unique business model' -- 'an ad-free social space that is supported by a one-of-a-kind mobile network.'
Wales also has a personal charity under his belt -- The Jimmy Wales Foundation, which focuses on championing freedom of speech causes worldwide.
Blomfield is the CEO and cofounder of Mondo, a new London fintech startup that's building a branchless bank using its debit card and accompanying app. Mondo cards are controlled through the app, and show users information about the purchases they make.
Mondo hasn't fully launched yet, but it has released a version of its card to alpha testers (you can see how we got on with it here).
Before founding Mondo, Blomfield was a cofounder of another London fintech startup: GoCardless. He left the company in 2013, and started Mondo in 2015.
Total amount raised: $3.1 million (£2.1 million)
Everledger is a startup that wants to make diamond theft a thing of the past.
It uses the blockchain -- the ledger of all bitcoin transactions -- to make a public record that valuable diamonds can be registered to, recording their unique characteristics. This should make it harder to pawn stolen diamonds, and help cut down on fraud.
The company was created by the Australian Leanne Kemp in 2015, and took part in the Barclays Techstars accelerator in June.
Nearly 900,000 diamonds have been registered to Everledger's platform already, and another 900,000 are queued up. Later down the line, it intends to start registering other luxury goods.
Total amount raised: $118,000 (£81,000)
Zoella is the well-known British YouTube vlogger who shares updates about fashion, make-up, and her life. Earlier in February 2016 it was announced that she has reached 10 million YouTube subscribers, and her videos have been watched over 1 billion times.
Zoella has also released two books, the first of which had the highest first-week sales for a novelist since records began in 1998. And her second book was named one of the highest-selling books of 2015.
Nicola Mendelsohn is Facebook's most senior executive outside of the US, and runs the social network's presence in Europe, the Middle East, and Africa.
Facebook opened its first office in Africa in July, and Mendelsohn was there to oversee the company's expansion.
Mendelsohn was given a CBE in the Queen's birthday honours list in June for her work in creative industries. Aside from her work at Facebook, she's also co-chair of the Creative Industries Council, a joint forum between the creative industry and the UK government.
Mendelsohn joined Facebook in July 2013, having previously served as executive chairman of advertising agency Karamarama. She spent 20 years working for advertising agencies before making the move to the social-networking giant.
Klein is a well-known investor in Europe, formerly of Index Ventures. He joined Index in 2007, and invested in successful tech companies such as Songkick, Chartbeat, and MyHeritage. He left the VC firm in May 2015 to focus on his personal investments.
Klein is also known for cofounding movie rental service LoveFilm and serving as its CEO, being one of Skype's original executives, and cofounding the Seedcamp startup accelerator program. He cofounded DIY computer company Kano with his cousin Alex Klein back in 2013.
In 2016 Klein is planning to work more closely with his father, venture capitalist Robin Klein, to invest in early stage technology companies. He's also calling on the government to support technology 'zebras' (growing technology companies,) not just big-name, billion-dollar 'unicorns.'
She works as Snapchat's general manager of UK sales, overseeing the company's first office outside the US. The company has made a series of hires for its European team from rival digital media and tech businesses over the past year.
Total amount raised: $1.2 billion (£830 million)
Somali-born Ismail Ahmed worked for the UN to help crackdown on money laundering before setting up WorldRemit in 2010. The startup offers an app that lets migrants send money back to family in places like Africa, India, and Latin America, known as remittance.
The company was valued at $500 million (£345 million) in a $100 million (£69 million) funding round last year, led by Silicon Valley venture capital firm Technology Crossover Ventures (TCV), which has also backed the likes of Facebook, Spotify, and Netflix. WorldRemit recently secured a further $45 million (£31 million) line of credit to fund growth and is processing 400,000 transactions a month.
Total amount raised: $147 million (£101 million)
Is Julian Assange part of the British tech scene -- or the Ecuadorian?
Because while the WikiLeaks founder is geographically located in London, he remains under Ecuador's jurisdiction: In 2012, he took refuge in the Ecuadorian Embassy in Knightsbridge to avoid extradition to Sweden for questioning over allegations of sexual assault and rape, and has remained there ever since.
WikiLeaks, his whistleblowing organisation, has kept busy during his unconventional asylum. Over the last year, it has published drafts of the controversial Trans-Pacific Partnership trade agreement, as well as documents from the Saudi Foreign Ministry and details on covert NSA spying.
In January, the pair of artificial intelligence (AI) experts pitched their AlphaGo agent against the European champion of board game Go and won. They're planning to take on the world champion in March.
Over the course of the last year, both Hassabis and Suleyman have acknowledged the potential impact AI could have on humanity. To ensure they get their message across, they have attended several conferences and given talks about the ethics of AI.
Rob Whitehead (CTO) and Herman Narula (CEO) are the two-man founder team behind Improbable, a London startup that wants to be the 'Google of simulation.'
The duo went to the University of Cambridge together, and in 2012 founded Improbable, which builds software that can power sophisticated simulations done by others. It provides the engine to do the heavy lifting, so you can get on with the business of actually modelling whatever it is you want to model.
The company's original focus was on gaming -- massive multiplayer game-worlds -- but it has applications in science, research, defence, and more.
It landed a $20 million (£14 million) in venture capital funding from well-respected US firm Andreessen Horowitz in 2015 -- its second ever investment in the UK.
In November 2015, it officially launched SpatialOS, its operating system. Alongside the launch, it announced an ambitious flagship project -- a virtual city run in collaboration with academics to answer questions about modern urban life. 'We're going to have an oracle for an entire city,' Narula told Business Insider. 'We'll be able to answer questions like 'what happens when we introduce autonomous vehicles,' or look at interactions between different things that have just been (previously) impossible.'
Total amount raised: $22 million (£15 million)
Eben Upton is the man behind the Raspberry Pi, the wildly popular -- and crazily cheap -- single-board computer used to promote computer science education and beloved by hobbyists.
The company launched its smallest and cheapest computer yet in November 2015: The Raspberry Pi Zero, which retails for just £3.30, or $5. Predictably, it sold out immediately.
In February 2016, British astronaut Tim Peake notched up a new first for the Upton's company -- using the 'AstroPi' in space at the International Space Station.
Former Googler Azmat Yusuf founded Citymapper in 2011 as a guide for Londoners to navigate the city's bus network. The app evolved into a multimodal travel platform and today it is used by millions of people worldwide.
In January, Citymapper raised $40 million (£28 million) from Index Ventures, Benchmark Capital, and a number of angel investors.
Citymapper is now available in 31 cities, including Hong Kong, Sydney, New York, Istanbul, Brussels, Tokyo, and San Francisco.
Total amount raised: $50 million (£34 million)
Silva is the former government technology advisor who was part of the team that created the Tech City UK initiative. He worked closely with George Osborne since 2006, and oversaw the growth of the UK's startup scene, playing a key role in the government's relationship with the growing tech cluster.
It was announced in January that Second Home had raised £7.5 million from investors including Yuri Milner, Tencent chairman Martin Lau, and venture capital firm Index Ventures, and that it would use the money to expand to Lisbon.
Silva is also planning to double the size of Second Home, and his plans include a 'huge indoor lake.'
Total amount raised: $10.7 million (£7.4 million)
Janine Gibson was appointed editor-in-chief of BuzzFeed UK in summer 2015. She started in the role last September after losing out to Katharine Viner in the race to replace Alan Rusbridger at the helm of The Guardian. Previously she was deputy editor at The Guardian. Prior to that, she was responsible for launching Guardian US, where she was editor-in-chief.
While leading Guardian US, Gibson played a key role in the Pulitzer Prize-winning coverage of the Edward Snowden leaks. The Oxford graduate began as a reporter in the media trade press, before becoming a media reporter at the Guardian in 1998 and rising within the organisation.
Total amount raised: $296 million (£204 million)
Gareth Williams is the CEO and cofounder of Skyscanner, the Edinburgh-based company behind one of the world's most popular flight comparison sites.

Skyscanner also has offices in Shenzhen, Beijing, Barcelona, Glasgow, Miami, Singapore, and Sofia. During 2015, the company grew the size of its workforce to approximately 800 people.
Total amount raised: $197 million (£136 million)
Sir Martin Sorrell is the CEO of the world's largest advertising agency holding group, WPP.
WPP's agencies spend a huge amount on tech platforms, on behalf of their clients. Sorrell told us in January that WPP agencies spent around $4 billion (£2.8 billion) with Google (up 38% from 2014) and $1 billion (£693 million) with Facebook (up 56% on 2014) last year. WPP predict digital advertising will account for 40-45% of its revenue by 2019.
Over the past 12 months, WPP has struck a number of technology partnership deals and acquisitions including: acquiring Google's digital media agency Essence; striking a year-long partnership deal between BuzzFeed and WPP's media-buying arm GroupM; launching an ad agency called Truffle Pig in partnership with Snapchat and The Daily Mail; and taking an equity stake in internet audience measurement company comScore.
WPP was the most prolific acquirer in the media and marketing industry in 2015, according to corporate advisory firm Ciesco.
José Neves launched Farfetch in 2008 as a way to marry boutique fashion retailers with customers, many of whom likely didn't know the products existed. The company has taken over $190 million (£130 million) in funding and is now worth over $1 billion (£690 million), making it a 'Unicorn.'
The company's investors include Conde Nast and Index Ventures. It's headquartered in London but has offices in New York, Los Angeles, Guimarães, Porto, São Paulo, Shanghai and Tokyo.
The average users spend over $600 (£400) on Farfetch in a single session and the company is doing over $160 million (£110 million) in revenue per year.
Total amount raised: $194.5 million (£135 million)
Button and Wood, Unruly co-CEOs, sold their video ad tech company to Rupert Murdoch's News Corp in September last year for $90 million (£62.4 million) in cash, plus up to a further $86 million (£59.6 million) if the London-based startup meets its performance targets.
Unruly specialises in serving and analysing video advertising and brand videos that appear outside the confines of YouTube and Facebook. Its technology allows marketers to buy 'native' video ad formats using automated technologies and track their performance across social. The company also offers an analytics tool that predicts whether videos are likely to viral.
Total amount raised: $25 million (£17.4 million)
Jon Reynolds started SwiftKey straight out of Cambridge University. The mission, according to Reynolds, is 'to make it easy for everyone to create and communicate on mobile.' The app, which is available on iPhone and Android, is used by more than 300 million people and relies heavily on artificial intelligence to predict what, exactly, the user is trying to say.
Microsoft was interested and acquired SwiftKey for $250 million (£175 million) in early 2016. The team will be incorporated into the company, meaning that Reynolds is now an employee of Microsoft who will work on AI, an area that Microsoft is intensely focused on.
Total amount raised: $21.6 million (£15 million)
Sean Murray is the CEO of Hello Games, a Guildford company that is building one of the most ambitious video games ever made. 'No Man's Sky' is an attempt to create an entire universe in an online video game environment, which will contain 18,446,744,073,709,551,616 planets.
And the game now has an official launch date: June 2016.
Nigel Eccles is the founder and CEO of Edinburgh-based FanDuel, which is a fantasy sports platform that allows people in North America to create one-day fantasy teams and enter them into leagues with cash prizes.
High-profile investors such as Google Capital, Time Warner Investments and Turner Sports backed FanDuel last summer in a $275 million (£176 million) round, which brought total investment in the company up to $361 million (£234 million).
FanDuel is perhaps the only British unicorn company not to offer its product to people in Britain. But that could be about to change as Eccles has hinted at the possibility of launching FanDuel in the UK for Premier League fans in the near future.
Total amount raised: $361 million (£250 million)
You have, of course, heard of 'Candy Crush.' You can't not. It's the insanely popular candy-swiping mobile app made by King Digital Entertainment.
Riccardo Zacconi is the man at the wheel at King, and he's had a very good year: In November 2015, Activision Blizzard (the gaming megacompany behind 'Call of Duty,' 'Starcraft,'' World of Warcraft,' and more) acquired King for a massive $5.9 billion (£4.1 billion).
Zacconi, who is Italian and lives in London, cofounded King in 2003, and is its CEO. At the time of the acquisition, the company boasted 330 million monthly active users.
Samir Desai is the founder of peer-to-peer business loan platform Funding Circle. The platform lets savers lend directly to businesses and over £1 billion has been lent over the platform since it launched in 2010. The company was valued at $1 billion (£690 million) last year.
Former management consultant Desai moved to the role of Global CEO last year to oversee expansion into new markets and in October Funding Circle entered Germany, Spain, and the Netherlands with the acquisition of Zencap. Desai had the idea for the business while working on a project at Northern Rock.

Other investors include Sir Richard Branson and Paypal founder Peter Thiel. Before TransferWise, Hinrikus was Skype's first employee. TransferWise went global in 2015 and has already passed the $1 billion transferred mark in the US.
Total amount raised: $90 million (£62 million)
The tech world was abruptly introduced to 27-year-old Londoner Julie Adenuga in June 2015, when she was announced as one of three global presenters for Beats 1.
Along with veteran BBC radio DJ Zane Lowe and New Yorker Ebro Darden, Adenuga is the face of Apple's flagship new internet radio station -- broadcasting from her London studio.
She may be a new face to techies, but she has strong roots in London's music scene. In 2010, she joined the city's underground radio station Rinse FM. 'We had no DJ experience, but we just played the music and were talking rubbish,' she said. 'It worked. Luckily.'
And let's not forget her family: Alongside Julie, there's also Joseph and Jamie Adenuga -- better known as London grime artists Skepta and JME.
William Shu launched his restaurant food delivery company in London in 2012 after realising it was hard to get good quality food delivered to your home or office.
The former investment banker has subsequently expanded Deliveroo to more than 30 UK cities and over 20 international cities. The growth has been fuelled with $200 million (£138 million) in venture capital funding, half of which was raised last November.
Shu has managed to attract popular London restaurants such as Dishoom, Ping Pong, and Dirty Burger to Deliveroo, where they can access an even larger customer base in exchange for approximately 30% of every transaction.
Total amount raised: $200 million (£138 million)
Eileen Burbidge founded investment fund Passion Capital in 2011 with Stefan Glaenzer and Robert Dighero. Since then, Passion Capital has invested in a series of successful London companies including DueDil, GoCardless, GoSquared, and Smarkets.
Burbidge was given an MBE in the Queen's birthday honours list in June for her services to business. And in July, Burbidge was named the UK Treasury's special envoy for fintech, a type of technology that London is particularly good at due to the tech sector's close proximity with banks and politics. She was also named as one of Prime Minister David Cameron's group of business advisors.
But the biggest news of 2015 for Burbidge was when she took the job of Chair of Tech City UK, the organisation that works to promote the UK's tech startups, in September. She's the new public figurehead for the organisation.
Prior to founding Passion Capital, Burbidge worked at Apple, Yahoo, Skype, and Sun Microsystems.
Total amount raised: $129 million (£89.5 million)
