Today we can reveal the inaugural South West Tech 50 – our ranking of the region’s most innovative technology companies.

YellowDog tops the list of outstanding tech creators after securing backing from both an independent judging panel and our readers.

The Bristol company helps companies harness computing power from underused sources.

Led by Gareth Williams, the firm – which has 2,500 users of its tech in more than 50 countries – once ran so much GPU for a client that it ranked as the eighth fastest supercomputer in the world.

It topped the ranking ahead of fellow Bristol business Ultraleap, which develops virtual touch technology.


“We are surprised and very flattered, given the quality of the other businesses in the South West,” Williams, who explained how the firm has had to adapt in the face of COVID-19, told BusinessCloud. “In Bristol alone you’ve got Graphcore, Ultraleap, Open Bionics, Blu Wireless… some amazing companies.

“We’re really, really, really, really pleased.”

Swindon-based Recycling Technologies, which turns all post-consumer plastics into oil, was third ahead of Filmily, which is based in Totnes and automatically curates films from events based on fan-based content.

Torbay’s Archilime, an architectural visualisation firm which includes a training academy, was fifth. City Science (Exeter), KETS (Bristol), Industrial Phycology (Bristol), (Poole) and DeGould (Exeter) completed the top 10.

BusinessCloud called on its readers to vote for companies from a 90-strong shortlist and saw 1,700 votes pour in.

A combination of these votes and choices from an expert judging panel determined the top 50. BusinessCloud editor Jonathan Symcox, who was among the judges, said: “Our inaugural South West Tech 50 ranking highlights the innovation springing up around the region.

“Bristol is clearly a UK leader in technology, as home to almost half of the top 50, but Plymouth, Exeter, Dorset and Cornwall are also well-represented.

“The South West is a real hotbed of innovation.”

The ranking was not open to large companies in other sectors with internal R&D departments, eCommerce retailers or technology infrastructure businesses such as telecoms. Agencies were required to be developing bespoke innovative solutions using the latest technologies to be considered.

The public vote on the shortlist attracted more than 1,700 votes. A panel of expert judges also made their choices. The final 50 ranking was decided from a combination of these.

The judging panel was comprised of:
•Vicky Hunter, entrepreneur engagement manager (South West), Tech Nation
•Dan Pritchard, co-founder, Tech South West
•Tom Fox, tech growth lead, KPMG
•Rosie Bennett, manager, University of Bath SETsquared Innovation Centre
•Jonathan Symcox, editor, BusinessCloud

South West Tech 50 is one of 11 regional tech innovation rankings from BusinessCloud which shines a light on the companies of all sizes who are doing amazing things with technology.
