Bristol is one of the UK’s foremost tech ecosystems, with some amazing young companies that have the potential to become global brands.

The most recent Tech Nation report identified Bristol as the most productive digital cluster in the UK, with more than 35,924 digital jobs and 225 start-ups, and accounting for 17pc of the UK’s high-growth firms.

As mentioned in our Bristol focus series, the city has an impressive concentration of international tech firms including supercomputer player Cray as well as Just Eat, Sony, Amazon and Oracle.

Bolstered by a strong university ecosystem that includes the University of Bristol and the University of the West of England, as well as the nearby University of Bath and Bath Spa University, the city is a magnet for tech investment and skills.

The University of Bristol sees more than 5,000 software engineers and other computer science-related students graduate every year.

Notable workspaces include Engine Shed, SETsquared and Webstart.

Useful meet-ups include Venturefest, TechSpark, and High Tech Bristol and Bath.

Bristol has also been chosen by Oracle to host one of its new global Startup Cloud Accelerators. A new lab space and science incubator, Unit DX, has also been established in Bristol.

The city’s heritage in the aviation industry was acknowledged by Airbus’ decision to launch a £40m Wing of the Future centre while Bristol Robotics Laboratory is now the UK’s leading academic centre for robotics research.

Here are 17 start-ups we believe are worth watching.
