Bristol is the sixth most active city in the UK by number of high-growth technology companies—behind London, Edinburgh, Cambridge, Manchester, and Glasgow—and fifth by total equity investment raised into these tech companies since 2011.

Technology is at the centre of Bristol’s startup scene: 216 of Bristol’s 596 tracked high-growth companies are in the tech sector. These 216 companies have raised £804m since 2011, employ over 3,600 people, and report a combined revenue turnover of £220m. 

Bristol is home to many notable high-growth tech successes, including semiconductor unicorn company Graphcore, acquired biotech spinout Ziylo, and haptic technology startup Ultraleap. The ecosystem is also heavily intertwined with the University of Bristol: 33 ambitious tech companies have been spun out of the institution since 2011. SETsquared—a business incubator launched by the University of Bristol—also plays a key role in the ecosystem, currently providing incubation services to over 80 ventures.

Graphcore has developed a semiconductor processing chip, optimised for running machine learning and artificial intelligence tasks faster. Its technology accelerates these applications both in servers and in the Cloud. It also provides an open source, machine learning framework in C++ and Python available to all developers to use and improve. 

The company was founded in 2016 and only moved from development to commercial production in 2019, but already supplies chips to large-scale partners such as Microsoft and Dell Technologies. Both of these partners are also investors into Graphcore. 

Graphcore has raised £365m across six rounds, reaching an impressive pre-money valuation of £1.13b this year. It raised £116m in February 2020, contributed by Ahren Innovation Capital, Amadeus Capital Partners, Baillie Gifford, Mayfair Equity Partners, Merian Chrysalis Investment Company, M&G Investments, and Sofina.

Rumours have been circulating of a Graphcore float as early as 2022, and potentially on the US Nasdaq exchange rather than the London Stock Exchange (like The Hut Group’s recent £4.5b float). This move is expected to value the company at at least $2b, but could rise to $10b (£7.5b).
