Graphcore was the "Office in Bristol".
In September 2015, hardware veterans Nigel Toon and Simon
Knowles were doing the rounds of venture capital offices in Silicon
Valley and London, touting their latest startup. The pair had a dazzling
track record – among other achievements they’d sold their previous
semiconductor company Icera to NVIDIA for $435 million (£346 million)
four years earlier. And their vision for Graphcore – a new Bristol-based
venture – was bold: they were building a new generation of microchips
known as intelligence processing units (IPUs), designed for the rapidly
approaching artificial intelligence age.
Yet early
reactions to their pitch for series A financing were distinctly muted.
“In many cases we were laughed out of court,” recalls Toon, Graphcore’s
CEO.
Typically, Toon says, they’d find a partner in
a VC firm who was excited by what they were doing. “But then they’d go
to their partner meeting, where the first question would be: ‘What’s
AI?’ It’s stunning to think that was a conversation that was happening
[as recently as] 2015.” From there, it was an uphill struggle. “Even if
they got the fact that AI might be interesting, they’d then say: ‘Your
business model is to build a chip for this AI thing? Well, nobody’s made
money from chip investments in the last 10 years.’”
Toon, who is 55 and has the mellifluous voice of an
old-school BBC continuity announcer, says that chip development, in the
eyes of most investors at the time, was considered highly capital
intensive, with returns failing to justify the upfront financing
required. “It’s not more capital intensive than software,” says Knowles,
Graphcore’s co-founder and CTO. “But software has this joyful property
that you can try it out in small scale first, whereas with a chip you’re
all in. If it doesn’t work, you’ve spent all your money.”
That
was 2015. Fast forward to today and, of course, AI hardware is a
white-hot category for investors, with VC funding for US AI companies
jumping by 72 per cent in 2018 to a record $9.3 billion (£7.4 billion), a
fifth straight year of growth, according to a report by CB Insights and
PwC.
What changed over those three years? Toon points to two
things. First, in 2016 traditional chip giant Intel acquired an AI
software and hardware startup called Nervana for $350 million (£280
million), raising eyebrows all over the Valley. Second, Google announced
it was going to build its own chips – evidence, Toon says, that
existing chips weren’t up to the task.
Knowles
describes the impact of Google’s decision as “seismic”. The fact that
Google thought AI was going to be a sufficiently big deal to justify the
pain and expense of building its own chip team helped make the
Graphcore founders’ case for them. He and Toon had been arguing that it
was worth digging deep financially to develop new processor hardware
because existing graphics processing units (GPUs) – used, for example,
in mobile phones, games consoles and personal computers – weren’t
designed for AI workloads such as machine learning and deep learning.
By
then, their startup was already ahead of the pack in developing a new
processor architecture. Soon top-tier investors – including Atomico, one
of Europe’s best-known VCs – were beating a path to their door.
Atomico, which went on to lead Graphcore’s $30 million (£24 million)
Series B round in July 2017, was followed six months later by one of the
Valley’s biggest guns, Sequoia Capital. At the time, Graphcore, having
recently closed its Series B, didn’t need investment – but the west
coast investor wasn't taking "No thanks" for an answer. “They came to
see us here in Bristol and said, ‘No, you don’t understand, we want to
invest in your business,’” laughs Toon. “So we work out terms and they
invest $50m into the company. And that’s one of the very few investments
they’ve made in the UK, because they’ve got so much opportunity on
their doorstep.”
Sequoia partner Matt Miller, who
now sits on Graphcore’s board, admits he was somewhat bemused to find
himself chasing down a company based in Bristol. “We knew there was an
opportunity for a new architecture that would be designed from the
ground up that could massively accelerate our entry into this AI age,
and we were trying to landscape all of these companies in China, the US
and Europe,” he says. “But our references were all pointing to this one
company in Bristol, whom we hadn’t met yet.”
A roar
of laughter distorts the line from the Valley. “Lemme tell you, if you’d
asked me a month prior if I’d ever [sit on] a board in Bristol I’d have
said ‘No way!’ It’s not your typical destination on your tour of
Europe. But to be honest, it’s been surprising for us in the Bay Area
because the quality of talent in the UK, and particularly in Bristol in
the semiconductor space, is very strong. The team they’ve been able to
build there is on a par with the best in the world.”
Following a $200 million (£160 million) Series D round in December 2018,
Graphcore was most recently valued at $1.7 billion (£1.36 billion),
with investors, innovators and large corporates now seemingly convinced
it will be the company to power the AI era in much the same way as
Cambridge-born chip giant ARM dominated mobile devices, shipping over
130 billion chips and reaching 70 per cent of the global population. The
opportunity at stake is nothing less than the future of AI, with
applications ranging from medical advances to autonomous vehicles, space
exploration and just about everything in between....
